Summary

The printing process can bypass local access protections to read files available through symlinks, bypassing local file restrictions. The printing process requires files in a specific format so arbitrary data cannot be read but it is possible that some local file information could be exposed. This vulnerability affects Firefox < 58.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Symlink Attack
    An attacker positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name. The endpoint file may be either output or input. If the file is output, the result is that the endpoint is modified, instead of a file at the intended location. Modifications to the endpoint file may include appending, overwriting, corrupting, changing permissions, or other modifications. In some variants of this attack the attacker may be able to control the change to a file while in other cases they cannot. The former is especially damaging since the attacker may be able to grant themselves increased privileges or insert false information, but the latter can also be damaging as it can expose sensitive information or corrupt or destroy vital system or application files. Alternatively, the endpoint file may serve as input to the targeted application. This can be used to feed malformed input into the target or to cause the target to process different information, possibly allowing the attacker to control the actions of the target or to cause the target to expose information to the attacker. Moreover, the actions taken on the endpoint file are undertaken with the permissions of the targeted user or application, which may exceed the permissions that the attacker would normally have.
  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

    descriptionMultiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, spoof the origin in audio capture prompts, trick the user in to providing HTTP credentials for another origin, spoof the addressbar contents, or execute arbitrary code. (CVE-2018-5089, CVE-2018-5090, CVE-2018-5091, CVE-2018-5092, CVE-2018-5093, CVE-2018-5094, CVE-2018-5095, CVE-2018-5097, CVE-2018-5098, CVE-2018-5099, CVE-2018-5100, CVE-2018-5101, CVE-2018-5102, CVE-2018-5103, CVE-2018-5104, CVE-2018-5109, CVE-2018-5114, CVE-2018-5115, CVE-2018-5117, CVE-2018-5122) Multiple security issues were discovered in WebExtensions. If a user were tricked in to installing a specially crafted extension, an attacker could potentially exploit these to gain additional privileges, bypass same-origin restrictions, or execute arbitrary code. (CVE-2018-5105, CVE-2018-5113, CVE-2018-5116) A security issue was discovered with the developer tools. If a user were tricked in to opening a specially crafted website with the developer tools open, an attacker could potentially exploit this to obtain sensitive information from other origins. (CVE-2018-5106) A security issue was discovered with printing. An attacker could potentially exploit this to obtain sensitive information from local files. (CVE-2018-5107) It was discovered that manually entered blob URLs could be accessed by subsequent private browsing tabs. If a user were tricked in to entering a blob URL, an attacker could potentially exploit this to obtain sensitive information from a private browsing context. (CVE-2018-5108) It was discovered that dragging certain specially formatted URLs to the addressbar could cause the wrong URL to be displayed. If a user were tricked in to opening a specially crafted website and dragging a URL to the addressbar, an attacker could potentially exploit this to spoof the addressbar contents. (CVE-2018-5111) It was discovered that WebExtension developer tools panels could open non-relative URLs. If a user were tricked in to installing a specially crafted extension and running the developer tools, an attacker could potentially exploit this to gain additional privileges. (CVE-2018-5112) It was discovered that ActivityStream images can attempt to load local content through file: URLs. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this in combination with another vulnerability that allowed sandbox protections to be bypassed, in order to obtain sensitive information from local files. (CVE-2018-5118) It was discovered that the reader view will load cross-origin content in violation of CORS headers. An attacker could exploit this to bypass CORS restrictions. (CVE-2018-5119). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

CVE-2018-5117, CVE-2018-5122)

Multiple security issues were discovered in WebExtensions.
If a user were tricked in to installing a specially crafted
extension, an attacker could potentially exploit these to
gain additional privileges, bypass same-origin restrictions,
or execute arbitrary code. (CVE-2018-5105, CVE-2018-5113,
CVE-2018-5116)

A security issue was discovered with the developer tools. If
a user were tricked in to opening a specially crafted
website with the developer tools open, an attacker could
potentially exploit this to obtain sensitive information
from other origins. (CVE-2018-5106)

A security issue was discovered with printing. An attacker
could potentially exploit this to obtain sensitive
information from local files. (CVE-2018-5107)

It was discovered that manually entered blob URLs could be
accessed by subsequent private browsing tabs. If a user were
tricked in to entering a blob URL, an attacker could
potentially exploit this to obtain sensitive information
from a private browsing context. (CVE-2018-5108)

It was discovered that dragging certain specially formatted

crafted website and dragging a URL to the addressbar, an
attacker could potentially exploit this to spoof the
addressbar contents. (CVE-2018-5111)

It was discovered that WebExtension developer tools panels
could open non-relative URLs. If a user were tricked in to
installing a specially crafted extension and running the
developer tools, an attacker could potentially exploit this
to gain additional privileges. (CVE-2018-5112)

It was discovered that ActivityStream images can attempt to
load local content through file: URLs. If a user were
tricked in to opening a specially crafted website, an
attacker could potentially exploit this in combination with
another vulnerability that allowed sandbox protections to be
bypassed, in order to obtain sensitive information from
