CVE-2022-23188 is a buffer overflow vulnerability (CWE-120) identified in Adobe Illustrator versions 25.4.3 and earlier, as well as 26.0.2 and earlier. The vulnerability arises from insecure handling of crafted malicious files by Illustrator, which can lead to a buffer overflow condition. This flaw allows an attacker to potentially execute arbitrary code within the context of the current user. Exploitation requires that the victim opens a specifically crafted malicious file in Adobe Illustrator, meaning user interaction is necessary. The vulnerability affects the confidentiality, integrity, and availability of the affected system by enabling code execution, which could lead to data theft, system compromise, or disruption of normal operations. No public exploits have been reported in the wild to date, and Adobe has not published official patches or updates addressing this vulnerability at the time of this analysis. The vulnerability was reserved in January 2022 and publicly disclosed in February 2022. Given the nature of Adobe Illustrator as a widely used professional graphic design tool, this vulnerability could be leveraged in targeted attacks, especially in environments where Illustrator files are exchanged frequently, such as creative agencies, marketing departments, and media companies.

For European organizations, the impact of CVE-2022-23188 can be significant, particularly for sectors relying heavily on Adobe Illustrator for design and creative workflows. Successful exploitation could lead to unauthorized code execution, enabling attackers to steal sensitive intellectual property, deploy malware, or move laterally within corporate networks. This could disrupt business continuity and damage reputations. Organizations in industries such as advertising, publishing, media production, and digital marketing are at higher risk due to frequent handling of Illustrator files. Additionally, government agencies and educational institutions using Adobe Illustrator could face risks related to data breaches or espionage. The requirement for user interaction limits mass exploitation but does not eliminate risk, especially in environments where users may open files from untrusted sources. The absence of known exploits in the wild reduces immediate threat levels but does not preclude future exploitation attempts. Given the medium severity rating and the potential for arbitrary code execution, organizations should treat this vulnerability seriously to prevent targeted attacks.

1. Implement strict email and file filtering policies to block or quarantine unsolicited or suspicious Illustrator files, especially from unknown sources. 2. Educate users on the risks of opening files from untrusted or unexpected senders, emphasizing caution with Illustrator files. 3. Employ application whitelisting and sandboxing techniques to limit the execution context of Adobe Illustrator, reducing the impact of potential exploitation. 4. Monitor network and endpoint logs for unusual behavior indicative of exploitation attempts, such as unexpected process launches or network connections originating from Illustrator. 5. Maintain up-to-date backups of critical data to enable recovery in case of compromise. 6. Regularly check Adobe’s official channels for patches or updates addressing this vulnerability and apply them promptly once available. 7. Consider deploying endpoint detection and response (EDR) tools capable of identifying exploitation behaviors related to buffer overflows and code execution. 8. Limit user privileges to reduce the impact scope if exploitation occurs, ensuring users operate with least privilege necessary.
