Summary

In Firefox Developer Tools it is possible that pasting the result of the 'Copy as cURL' command into a command shell on macOS will cause the execution of unintended additional bash script commands if the URL was maliciously crafted. This is the result of an issue with the native version of Bash on macOS. *Note: This issue only affects macOS. Other operating systems are unaffected.*. This vulnerability affects Firefox < 66.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.
  • Command Delimiters
    An attack of this type exploits a programs' vulnerabilities that allows an attacker's commands to be concatenated onto a legitimate command with the intent of targeting other resources such as the file system or database. The system that uses a filter or a blacklist input validation, as opposed to whitelist validation is vulnerable to an attacker who predicts delimiters (or combinations of delimiters) not present in the filter or blacklist. As with other injection attacks, the attacker uses the command delimiter payload as an entry point to tunnel through the application and activate additional attacks through SQL queries, shell commands, network scanning, and so on.
  • Exploiting Multiple Input Interpretation Layers
    An attacker supplies the target software with input data that contains sequences of special characters designed to bypass input validation logic. This exploit relies on the target making multiples passes over the input data and processing a "layer" of special characters with each pass. In this manner, the attacker can disguise input that would otherwise be rejected as invalid by concealing it with layers of special/escape characters that are stripped off by subsequent processing steps. The goal is to first discover cases where the input validation layer executes before one or more parsing layers. That is, user input may go through the following logic in an application: In such cases, the attacker will need to provide input that will pass through the input validator, but after passing through parser2, will be converted into something that the input validator was supposed to stop.
  • Argument Injection
    An attacker changes the behavior or state of a targeted application through injecting data or command syntax through the targets use of non-validated and non-filtered arguments of exposed services or methods.
  • OS Command Injection
    In this type of an attack, an adversary injects operating system commands into existing application functions. An application that uses untrusted input to build command strings is vulnerable. An adversary can leverage OS command injection in an application to elevate privileges, execute arbitrary commands and compromise the underlying operating system.

    descriptionThe version of Firefox installed on the remote macOS or Mac OS X host is prior to 66.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-07 advisory. - A use-after-free vulnerability can occur when a raw pointer to a DOM element on a page is obtained using JavaScript and the element is then removed while still in use. This results in a potentially exploitable crash. (CVE-2019-9790) - The type inference system allows the compilation of functions that can cause type confusions between arbitrary objects when compiled through the IonMonkey just-in-time (JIT) compiler and when the constructor function is entered through on-stack replacement (OSR). This allows for possible arbitrary reading and writing of objects during an exploitable crash. (CVE-2019-9791) - The IonMonkey just-in-time (JIT) compiler can leak an internal JSOPTIMIZEDOUT magic value to the running script during a bailout. This magic value can then be used by JavaScript to achieve memory corruption, which results in a potentially exploitable crash. (CVE-2019-9792) - A mechanism was discovered that removes some bounds checking for string, array, or typed array accesses if Spectre mitigations have been disabled. This vulnerability could allow an attacker to create an arbitrary value in compiled JavaScript, for which the range analysis will infer a fully controlled, incorrect range in circumstances where users have explicitly disabled Spectre mitigations. Note: Spectre mitigations are currently enabled for all users by default settings. (CVE-2019-9793) - A vulnerability was discovered where specific command line arguments are not properly discarded during Firefox invocation as a shell handler for URLs. This could be used to retrieve and execute files whose location is supplied through these command line arguments if Firefox is configured as the default URI handler for a given URI scheme in third party applications and these applications insufficiently sanitize URL data. Note: This issue only affects Windows operating systems. Other operating systems are unaffected. (CVE-2019-9794) - A vulnerability where type-confusion in the IonMonkey just-in-time (JIT) compiler could potentially be used by malicious JavaScript to trigger a potentially exploitable crash. (CVE-2019-9795) - A use-after-free vulnerability can occur when the SMIL animation controller incorrectly registers with the refresh driver twice when only a single registration is expected. When a registration is later freed with the removal of the animation controller element, the refresh driver incorrectly leaves a dangling pointer to the driver

        Note: This issue only affects Windows operating systems.
        Other operating systems are unaffected. (CVE-2019-9794)
    
      - A vulnerability where type-confusion in the IonMonkey
        just-in-time (JIT) compiler could potentially be used by
        malicious JavaScript to trigger a potentially
        exploitable crash. (CVE-2019-9795)
    
      - A use-after-free vulnerability can occur when the SMIL
        animation controller incorrectly registers with the
        refresh driver twice when only a single registration is
        expected. When a registration is later freed with the
        removal of the animation controller element, the refresh
        driver incorrectly leaves a dangling pointer to the
        driver's observer array. (CVE-2019-9796)
    
      - Cross-origin images can be read in violation of the
        same-origin policy by exporting an image after using
        createImageBitmap to read the image and
        then rendering the resulting bitmap image within a
        canvas element. (CVE-2019-9797)
    
      - On Android systems, Firefox can load a library from
        APITRACELIB, which is writable by all users
        and applications. This could allow malicious third party
        applications to execute a man-in-the-middle attack if a
        malicious code was written to that location and loaded.
         Note: This issue only affects Android. Other
        operating systems are unaffected. (CVE-2019-9798)
    
      - Insufficient bounds checking of data during inter-
        process communication might allow a compromised content
        process to be able to read memory from the parent
        process under certain conditions. (CVE-2019-9799)
    
      - Firefox will accept any registered Program ID as an
        external protocol handler and offer to launch this local
        application when given a matching URL on Windows
        operating systems. This should only happen if the
        program has specifically registered itself as a URL
        Handler in the Windows registry.  Note: This issue
        only affects Windows operating systems. Other operating
        systems are unaffected. (CVE-2019-9801)
    
      - If a Sandbox content process is compromised, it can
        initiate an FTP download which will then use a child
        process to render the downloaded data. The downloaded
        data can then be passed to the Chrome process with an
        arbitrary file length supplied by an attacker, bypassing
        sandbox protections and allow for a potential memory
        read of adjacent data from the privileged Chrome
        process, which may include sensitive data.
        (CVE-2019-9802)
    
      - The Upgrade-Insecure-Requests (UIR) specification states
        that if UIR is enabled through Content Security Policy
        (CSP), navigation to a same-origin URL must be upgraded
        to HTTPS. Firefox will incorrectly navigate to an HTTP
        URL rather than perform the security upgrade requested
        by the CSP in some circumstances, allowing for potential
        man-in-the-middle attacks on the linked resources.
        (CVE-2019-9803)
    
      - In Firefox Developer Tools it is possible that pasting
        the result of the 'Copy as cURL'  command into a command
        shell on macOS will cause the execution of unintended
        additional bash script commands if the URL was
        maliciously crafted. This is the result of an issue with
        the native version of Bash on macOS.  Note: This
        issue only affects macOS. Other operating systems are
        unaffected. (CVE-2019-9804)
    
      - A latent vulnerability exists in the Prio library where
        data may be read from uninitialized memory for some
        functions, leading to potential memory corruption.
        (CVE-2019-9805)
    
      - A vulnerability exists during authorization prompting
        for FTP transaction where successive modal prompts are
        displayed and cannot be immediately dismissed. This
        allows for a denial of service (DOS) attack.
        (CVE-2019-9806)
    
      - When arbitrary text is sent over an FTP connection and a
        page reload is initiated, it is possible to create a
        modal alert message with this text as the content. This
        could potentially be used for social engineering
        attacks. (CVE-2019-9807)
    
      - If the source for resources on a page is through an FTP
        connection, it is possible to trigger a series of modal
        alert messages for these resources through invalid
        credentials or locations. These messages cannot be
        immediately dismissed, allowing for a denial of service
        (DOS) attack. (CVE-2019-9809)
    
      - If WebRTC permission is requested from documents with
        data: or blob: URLs, the permission notifications do not
        properly display the originating domain. The
        notification states Unknown origin as the requestee,
        leading to user confusion about which site is asking for
        this permission. (CVE-2019-9808)

    descriptionThe version of Firefox installed on the remote Windows host is prior to 66.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-07 advisory. - A use-after-free vulnerability can occur when a raw pointer to a DOM element on a page is obtained using JavaScript and the element is then removed while still in use. This results in a potentially exploitable crash. (CVE-2019-9790) - The type inference system allows the compilation of functions that can cause type confusions between arbitrary objects when compiled through the IonMonkey just-in-time (JIT) compiler and when the constructor function is entered through on-stack replacement (OSR). This allows for possible arbitrary reading and writing of objects during an exploitable crash. (CVE-2019-9791) - The IonMonkey just-in-time (JIT) compiler can leak an internal JSOPTIMIZEDOUT magic value to the running script during a bailout. This magic value can then be used by JavaScript to achieve memory corruption, which results in a potentially exploitable crash. (CVE-2019-9792) - A mechanism was discovered that removes some bounds checking for string, array, or typed array accesses if Spectre mitigations have been disabled. This vulnerability could allow an attacker to create an arbitrary value in compiled JavaScript, for which the range analysis will infer a fully controlled, incorrect range in circumstances where users have explicitly disabled Spectre mitigations. Note: Spectre mitigations are currently enabled for all users by default settings. (CVE-2019-9793) - A vulnerability was discovered where specific command line arguments are not properly discarded during Firefox invocation as a shell handler for URLs. This could be used to retrieve and execute files whose location is supplied through these command line arguments if Firefox is configured as the default URI handler for a given URI scheme in third party applications and these applications insufficiently sanitize URL data. Note: This issue only affects Windows operating systems. Other operating systems are unaffected. (CVE-2019-9794) - A vulnerability where type-confusion in the IonMonkey just-in-time (JIT) compiler could potentially be used by malicious JavaScript to trigger a potentially exploitable crash. (CVE-2019-9795) - A use-after-free vulnerability can occur when the SMIL animation controller incorrectly registers with the refresh driver twice when only a single registration is expected. When a registration is later freed with the removal of the animation controller element, the refresh driver incorrectly leaves a dangling pointer to the driver

        animation controller incorrectly registers with the
        refresh driver twice when only a single registration is
        expected. When a registration is later freed with the
        removal of the animation controller element, the refresh
        driver incorrectly leaves a dangling pointer to the
        driver's observer array. (CVE-2019-9796)
    
      - Cross-origin images can be read in violation of the
        same-origin policy by exporting an image after using
        createImageBitmap to read the image and
        then rendering the resulting bitmap image within a
        canvas element. (CVE-2019-9797)
    
      - On Android systems, Firefox can load a library from
        APITRACELIB, which is writable by all users
        and applications. This could allow malicious third party
        applications to execute a man-in-the-middle attack if a
        malicious code was written to that location and loaded.
         Note: This issue only affects Android. Other
        operating systems are unaffected. (CVE-2019-9798)
    
      - Insufficient bounds checking of data during inter-
        process communication might allow a compromised content
        process to be able to read memory from the parent
        process under certain conditions. (CVE-2019-9799)
    
      - Firefox will accept any registered Program ID as an
        external protocol handler and offer to launch this local
        application when given a matching URL on Windows
        operating systems. This should only happen if the
        program has specifically registered itself as a URL
        Handler in the Windows registry.  Note: This issue
        only affects Windows operating systems. Other operating
        systems are unaffected. (CVE-2019-9801)
    
      - If a Sandbox content process is compromised, it can
        initiate an FTP download which will then use a child
        process to render the downloaded data. The downloaded
        data can then be passed to the Chrome process with an
        arbitrary file length supplied by an attacker, bypassing
        sandbox protections and allow for a potential memory
        read of adjacent data from the privileged Chrome
