Module Overview

Name: Firefox MCallGetProperty Write Side Effects Use After Free Exploit
Module: exploit/multi/browser/firefox_jit_use_after_free
Source code: modules/exploits/multi/browser/firefox_jit_use_after_free.rb
Disclosure date: 2020-11-18
Last modification time: 2022-02-26 12:35:38 +0000
Supported architecture(s): x64
Supported platform(s): Linux, Windows
Target service / protocol: -
Target network port(s): -
List of CVEs: CVE-2020-26950

This modules exploits CVE-2020-26950, a use after free exploit in Firefox. The MCallGetProperty opcode can be emitted with unmet assumptions resulting in an exploitable use-after-free condition. This exploit uses a somewhat novel technique of spraying ArgumentsData structures in order to construct primitives. The shellcode is forced into executable memory via the JIT compiler, and executed by writing to the JIT region pointer. This exploit does not contain a sandbox escape, so firefox must be run with the MOZ_DISABLE_CONTENT_SANDBOX environment variable set, in order for the shellcode to run successfully. This vulnerability affects Firefox < 82.0.3, Firefox ESR < 78.4.1, and Thunderbird < 78.4.2, however only Firefox <= 79 is supported as a target. Additional work may be needed to support other versions such as Firefox 82.0.1.

Module Ranking and Traits

Module Ranking:

  • manual: The exploit is unstable or difficult to exploit and is basically a DoS. This ranking is also used when the module has no use unless specifically configured by the user (e.g.: exploit/windows/smb/psexec). More information about ranking can be found here.

Reliability:

  • repeatable-session: The module is expected to get a shell every time it runs.

Stability:

  • crash-safe: Module should not crash the service.

Side Effects:

  • ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).

Knowledge Base

Vulnerable Application

This modules exploits CVE-2020-26950, a use after free exploit in Firefox. The MCallGetProperty opcode can be emitted with unmet assumptions resulting in an exploitable use-after-free condition.

This exploit uses a somewhat novel technique of spraying ArgumentsData structures in order to construct primitives. The shellcode is forced into executable memory via the JIT compiler, and executed by writing to the JIT region pointer.

This exploit does not contain a sandbox escape, so firefox must be run with the MOZ_DISABLE_CONTENT_SANDBOX environment variable set, in order for the shellcode to run successfully.

This vulnerability affects Firefox < 82.0.3, Firefox ESR < 78.4.1, and Thunderbird < 78.4.2, however only Firefox < 82 is supported as a target. Additional work may be needed to support other versions such as Firefox 82.0.1.

Vulnerable Application Installation Steps

You can download and run a vulnerable firefox version on Linux with the following commands: wget https://ftp.mozilla.org/pub/firefox/releases/79.0/linux-x86_64/en-US/firefox-79.0.tar.bz2 tar xvf firefox-79.0.tar.bz2 cd firefox MOZ_DISABLE_CONTENT_SANDBOX=1 ./firefox

You can also download a vulnerable firefox version for Windows from the following location: https://ftp.mozilla.org/pub/firefox/releases/79.0/win64/en-US/

Verification Steps

  1. Do: use exploit/multi/browser/firefox_jit_use_after_free
  2. Do: set payload [PAYLOAD]
  3. Do: set URIPATH /
  4. Do: set LHOST [IP]
  5. Do: set SRVHOST [IP]
  6. Do: exploit

Options

DEBUG_EXPLOIT

Show debug information during exploitation. This will display details of the exploit during exploitation, which is useful for debugging.
