CVE-2022-23192 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Illustrator versions 25.4.3 and earlier, as well as 26.0.2 and earlier. This vulnerability allows an attacker to read memory outside the intended buffer boundaries when processing specially crafted Illustrator files. The out-of-bounds read can lead to disclosure of sensitive memory contents, potentially exposing confidential information such as cryptographic keys, user data, or internal application state. A significant consequence of this vulnerability is that it can be leveraged to bypass security mitigations like Address Space Layout Randomization (ASLR), which is designed to prevent exploitation by randomizing memory addresses. Exploitation requires user interaction, specifically that the victim opens a maliciously crafted Illustrator file, which triggers the out-of-bounds read. There are no known exploits in the wild at the time of this report, and no official patches have been linked or released yet. The vulnerability does not allow direct code execution or privilege escalation but can be a stepping stone in a multi-stage attack by leaking memory layout information to facilitate further exploitation. The vulnerability affects a widely used creative software product, Adobe Illustrator, which is prevalent in graphic design, publishing, and marketing sectors.

For European organizations, the impact of CVE-2022-23192 primarily revolves around confidentiality breaches and potential facilitation of more advanced attacks. Organizations in sectors relying heavily on Adobe Illustrator, such as advertising agencies, media companies, and design studios, could have sensitive intellectual property or client data exposed if malicious files are opened. The ability to bypass ASLR increases the risk that attackers could chain this vulnerability with others to achieve remote code execution or persistent compromise. Although the vulnerability requires user interaction, targeted spear-phishing or supply chain attacks distributing malicious Illustrator files could lead to significant data leaks or compromise of internal networks. The impact on integrity and availability is limited directly but could be consequential if leveraged in broader attack campaigns. Given the lack of known exploits, immediate widespread damage is unlikely, but the vulnerability represents a medium-term risk, especially in environments with high exposure to untrusted files or insufficient endpoint protections.

1. Implement strict email and file filtering policies to block or quarantine unsolicited or suspicious Illustrator files, especially from unknown sources. 2. Educate users in creative and marketing departments about the risks of opening files from untrusted origins and encourage verification of file sources. 3. Use endpoint detection and response (EDR) solutions capable of monitoring Adobe Illustrator processes for anomalous behavior indicative of exploitation attempts. 4. Apply application whitelisting and sandboxing techniques to isolate Illustrator processes, limiting the impact of potential memory disclosure. 5. Monitor Adobe’s security advisories closely and prioritize patch deployment once an official fix is released. 6. Employ network segmentation to restrict access to sensitive data repositories from workstations running Illustrator, reducing the risk of lateral movement. 7. Consider disabling or restricting the use of Illustrator on systems that do not require it, minimizing the attack surface. 8. Use memory protection tools and enhanced logging to detect attempts to exploit memory corruption vulnerabilities.
