Description

Adobe Illustrator versions 26.3.1 (and earlier) and 25.4.6 (and earlier) are affected by a Use After Free vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Technical Analysis

CVE-2022-34263 is a Use After Free (CWE-416) vulnerability affecting Adobe Illustrator versions 26.3.1 and earlier, as well as 25.4.6 and earlier. This vulnerability arises when the application improperly manages memory, specifically freeing memory that is still in use, which can lead to arbitrary code execution within the context of the current user. Exploitation requires the victim to open a maliciously crafted Illustrator file, triggering the vulnerability. This means that user interaction is necessary for the attack to succeed, limiting the attack vector to scenarios where a user is tricked into opening a compromised file, such as via phishing or malicious downloads. The vulnerability does not require elevated privileges or authentication, but the impact is constrained to the permissions of the user running Illustrator. No known exploits are currently reported in the wild, and Adobe has not provided patch links in the provided data, indicating that remediation may require updating to newer versions beyond those specified or applying vendor advisories. The vulnerability's medium severity rating reflects the balance between the potential for arbitrary code execution and the requirement for user interaction and limited scope of impact to the current user context.

Potential Impact

For European organizations, the impact of CVE-2022-34263 can be significant, particularly for those heavily reliant on Adobe Illustrator for graphic design, marketing, and creative workflows. Successful exploitation could allow attackers to execute arbitrary code, potentially leading to data theft, installation of malware, or lateral movement within the network if the compromised user has elevated access. However, since the vulnerability requires user interaction and affects only the current user's privileges, the risk is somewhat mitigated compared to remote code execution vulnerabilities that do not require user action. Organizations in sectors such as media, advertising, publishing, and design agencies are at higher risk due to frequent use of Illustrator and the likelihood of receiving files from external sources. Additionally, if Illustrator is used on systems with access to sensitive data or critical infrastructure, the compromise could have broader implications. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as threat actors may develop exploits over time.

Mitigation Recommendations

To mitigate CVE-2022-34263 effectively, European organizations should: 1) Ensure all Adobe Illustrator installations are updated to the latest available versions beyond 26.3.1 and 25.4.6, as vendors typically release patches addressing such vulnerabilities. 2) Implement strict email and file filtering policies to detect and block malicious Illustrator files, including sandboxing attachments to observe behavior before delivery. 3) Educate users on the risks of opening unsolicited or suspicious files, emphasizing verification of file sources, especially in creative departments. 4) Employ application whitelisting and endpoint detection and response (EDR) solutions to monitor and block unauthorized code execution attempts. 5) Restrict Illustrator usage to users with the minimum necessary privileges to limit the impact of potential exploitation. 6) Regularly audit and monitor systems for unusual activity that could indicate exploitation attempts. 7) Coordinate with Adobe support channels to obtain and apply official patches or workarounds as they become available.
