Vulnerabilities > CVE-2017-7768 - Information Exposure vulnerability in Mozilla Firefox
Summary
The Mozilla Maintenance Service can be invoked by an unprivileged user to read 32 bytes of any arbitrary file on the local system by convincing the service that it is reading a status file provided by the Mozilla Windows Updater. The Mozilla Maintenance Service executes with privileged access, bypassing system protections against unprivileged users. Note: This attack requires local system access and only affects Windows. Other operating systems are not affected. This vulnerability affects Firefox ESR < 52.2 and Firefox < 54.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Subverting Environment Variable Values The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
- Footprinting An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
- Exploiting Trust in Client (aka Make the Client Invisible) An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
- Browser Fingerprinting An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
- Session Credential Falsification through Prediction This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

It is, therefore, affected by multiple vulnerabilities : - Multiple memory corruption issues exist that allow an unauthenticated, remote attacker to execute arbitrary code by convincing a user to visit a specially crafted website. (CVE-2017-5470) - A use-after-free error exists in the EndUpdate() function in nsCSSFrameConstructor.cpp that is triggered when reconstructing trees during regeneration of CSS layouts. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted website, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-5472) - A use-after-free error exists in the Reload() function in nsDocShell.cpp that is triggered when using an incorrect URL during the reload of a docshell. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7749) - A use-after-free error exists in the Hide() function in nsDocumentViewer.cpp that is triggered when handling track elements. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7750) - A use-after-free error exists in the nsDocumentViewer class in nsDocumentViewer.cpp that is triggered when handling content viewer listeners. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7751) - A use-after-free error exists that is triggered when handling events while specific user interaction occurs with the input method editor (IME). An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7752) - An out-of-bounds read error exists in the IsComplete() function in WebGLTexture.cpp that is triggered when handling textures. An unauthenticated, remote attacker can exploit this to disclose memory contents. (CVE-2017-7754) - A privilege escalation vulnerability exists due to improper loading of dynamic-link library (DLL) files. A local attacker can exploit this, via a specially crafted DLL file in the installation path, to inject and execute arbitrary code. (CVE-2017-7755) - A use-after-free error exists in the SetRequestHead() function in XMLHttpRequestMainThread.cpp that is triggered when logging XML HTTP Requests (XHR). An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7756) - A use-after-free error exists in ActorsParent.cpp due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7757) - An out-of-bounds read error exists in the AppendAudioSegment() function in TrackEncoder.cpp that is triggered when the number of channels in an audio stream changes while the Opus encoder is in use. An unauthenticated, remote attacker can exploit this to disclose sensitive information. (CVE-2017-7758) - A flaw exists in the NS_main() function in updater.cpp due to improper validation of input when handling callback file path parameters. A local attacker can exploit this to manipulate files in the installation directory. (CVE-2017-7760) - A flaw exists in the Maintenance Service helper.exe application that is triggered as permissions for a temporary directory are set to writable by non-privileged users. A local attacker can exploit this to delete arbitrary files on the system. (CVE-2017-7761) - A flaw exists in the isLabelSafe() function in nsIDNService.cpp that is triggered when handling characters from different unicode blocks. An unauthenticated, remote attacker can exploit this, via a specially crafted IDN domain, to spoof a valid URL and conduct phishing attacks. (CVE-2017-7764) - A flaw exists that is triggered due to improper parsing of long filenames when handling downloaded files.
