Stack-based buffer overflow in CA Anti-Virus engine CAB processing

IdentifiersCVE-2007-2864CWE-121

CVE-2007-2864 is a stack-based buffer overflow in the CA (formerly Computer Associates) Anti-Virus engine's processing of CAB archives. The flaw exists before content update 30.6 and is triggered when the engine parses a .CAB file containing a large invalid value in the coffFiles field. A remote attacker can supply a crafted CAB archive to the vulnerable scanning engine, causing memory corruption on the stack and potentially achieving arbitrary code execution.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation may allow a remote, unauthenticated attacker to execute arbitrary code in the security context of the affected anti-virus engine. Where code execution is not achieved, the vulnerability can still cause a denial-of-service condition by crashing the scanning process or affected service.

Mitigation

If you can’t patch tonight, do this now.

Ensure the latest available content update is installed, with a minimum of version 30.6. Until patching is complete, reduce exposure by limiting delivery or processing of untrusted CAB files and restricting access to affected services or workflows that automatically scan attacker-supplied archives where possible.

Remediation

Patch, then assume compromise.

Apply CA Anti-Virus engine content update 30.6 or later. Verify that affected CA products using the vulnerable anti-virus engine have been updated and that engine/signature content is current across all deployed systems.

ca_cab.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit exploit module targeting a stack buffer overflow vulnerability in CA eTrust Antivirus 8.1.637 (CVE-2007-2864). The exploit works by generating a specially crafted CAB file ('msf.cab' by default) that, when scanned or opened by the vulnerable antivirus engine on Windows 2000 or Windows XP SP0/SP1, triggers a buffer overflow and allows arbitrary code execution. The module is written in Ruby and leverages Metasploit's FILEFORMAT exploit mixin. The payload is customizable, with a maximum size of 250 bytes, and is inserted into the CAB file at the appropriate offset to gain control of execution flow. The exploit does not require network interaction; the attack vector is local, relying on the target system processing the malicious file. The repository structure is typical for a Metasploit module, with all logic contained in a single Ruby file.
