Description Preview

Adobe Illustrator versions 26.5.2 (and earlier) and 27.2.0 (and earlier) contain an out-of-bounds write vulnerability (CWE-787) that could allow an attacker to execute arbitrary code in the context of the current user. The vulnerability requires user interaction, as the victim must open a specially crafted malicious file to trigger the exploit. This security flaw could potentially lead to complete system compromise if the affected user has elevated privileges.

Overview

This vulnerability (CVE-2023-25861) affects Adobe Illustrator software and is classified as an out-of-bounds write vulnerability (CWE-787). When exploited, an attacker could cause the application to write data past the end of the intended buffer, potentially leading to memory corruption and arbitrary code execution. The attack vector requires social engineering to convince a user to open a malicious file in Illustrator. Once executed, the malicious code would run with the same privileges as the current user, potentially allowing an attacker to take control of the affected system, access sensitive information, or install additional malware.

Remediation

Users should immediately update to the latest version of Adobe Illustrator that contains fixes for this vulnerability. Adobe has addressed this issue in their security bulletin APSB23-19. General security best practices that should also be followed include:

  1. Keep all software updated to the latest versions
  2. Exercise caution when opening files from untrusted sources
  3. Implement the principle of least privilege for user accounts
  4. Use endpoint protection solutions that can detect and block exploitation attempts
  5. Consider application sandboxing technologies to limit the impact of potential exploits
