CVE-2022-23187 is a buffer overflow vulnerability (CWE-120) found in Adobe Illustrator version 26.0.3 and earlier. The vulnerability arises from insecure handling of crafted files, which can cause a buffer overflow condition when such a file is opened in Illustrator. This overflow can potentially allow an attacker to execute arbitrary code within the context of the current user. Exploitation requires user interaction, specifically the victim must open a maliciously crafted Illustrator file. There are no known exploits in the wild as of the published date. The vulnerability affects the confidentiality, integrity, and availability of the system by enabling code execution, which could lead to data compromise or system manipulation. However, the attack vector is limited by the need for user action and the scope is confined to systems running vulnerable versions of Adobe Illustrator. No patches or updates are linked in the provided information, indicating that mitigation may rely on vendor updates or workarounds. The vulnerability is classified as medium severity by the vendor, reflecting the balance between potential impact and exploitation complexity.

For European organizations, the impact of CVE-2022-23187 could be significant in environments where Adobe Illustrator is widely used, such as graphic design firms, marketing agencies, publishing houses, and corporate communications departments. Successful exploitation could lead to unauthorized code execution, potentially allowing attackers to steal sensitive intellectual property, manipulate design files, or establish footholds for further network intrusion. Given that Illustrator files are commonly exchanged via email or shared drives, the risk of social engineering attacks leveraging this vulnerability is notable. However, the requirement for user interaction reduces the likelihood of automated widespread exploitation. Organizations handling sensitive or proprietary design data may face confidentiality breaches, while integrity and availability could be compromised if attackers deploy malware or ransomware post-exploitation. The absence of known exploits in the wild suggests a lower immediate threat but does not eliminate future risk, especially as threat actors may develop exploits over time.

To mitigate this vulnerability, European organizations should prioritize the following measures: 1) Update Adobe Illustrator to the latest version once a patch is released by Adobe, as this is the most effective mitigation. 2) Implement strict email and file-sharing policies to limit the receipt and opening of unsolicited or suspicious Illustrator files, including the use of sandboxing or file scanning solutions that can detect malformed files. 3) Educate users about the risks of opening files from untrusted sources and encourage verification of file origins before opening. 4) Employ endpoint protection solutions capable of detecting anomalous behavior indicative of exploitation attempts. 5) Restrict user privileges to minimize the impact of potential code execution, ensuring users operate with least privilege necessary. 6) Monitor network and host logs for unusual activity that could indicate exploitation attempts. These targeted actions go beyond generic advice by focusing on controlling the attack vector (crafted files) and limiting user exposure.
