CVE-2022-30651 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe InCopy versions 17.2 and earlier, as well as 16.4.1 and earlier. The vulnerability arises when Adobe InCopy parses a specially crafted file, leading to a read operation beyond the allocated memory boundary. This memory corruption flaw can potentially be leveraged by an attacker to execute arbitrary code within the security context of the current user. Exploitation requires user interaction, specifically that the victim opens a maliciously crafted InCopy file. The vulnerability does not appear to have been exploited in the wild as of the published date. The flaw is significant because it can lead to arbitrary code execution, which may allow attackers to compromise the affected system, steal sensitive data, or perform unauthorized actions. However, the attack vector is limited by the need for user interaction and the requirement that the victim opens a malicious file, which somewhat reduces the likelihood of widespread exploitation. No official patch links were provided in the source information, indicating that remediation may require updating to a newer, unaffected version once available or applying vendor-supplied patches. The vulnerability affects a widely used Adobe product in publishing and content creation workflows, making it relevant for organizations relying on Adobe InCopy for document collaboration and editorial processes.

For European organizations, the impact of CVE-2022-30651 could be significant in sectors that heavily utilize Adobe InCopy, such as media, publishing, advertising, and creative agencies. Successful exploitation could lead to unauthorized code execution, resulting in data breaches, intellectual property theft, or disruption of editorial workflows. Given that Adobe InCopy is often used in collaborative environments, a compromised user account could serve as a pivot point for lateral movement within an organization's network. Confidentiality and integrity of sensitive editorial content could be at risk. However, the requirement for user interaction and opening a malicious file limits the attack surface primarily to targeted phishing or social engineering campaigns rather than widespread automated attacks. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation. Organizations with remote or hybrid workforces may face increased risk if users handle InCopy files from untrusted sources. Overall, the threat is medium but should be taken seriously due to the potential for code execution and the strategic importance of affected industries in Europe.

1. Immediate mitigation should focus on user awareness and training to recognize and avoid opening suspicious or unexpected InCopy files, especially from untrusted sources. 2. Implement strict email filtering and attachment scanning to detect and quarantine potentially malicious InCopy files before they reach end users. 3. Enforce the principle of least privilege for users running Adobe InCopy to limit the impact of potential code execution. 4. Monitor and restrict file sharing channels where InCopy files are exchanged to reduce exposure to crafted malicious files. 5. Maintain up-to-date backups of critical editorial and content files to enable recovery in case of compromise. 6. Regularly check Adobe’s security advisories for patches or updates addressing this vulnerability and apply them promptly once available. 7. Employ endpoint detection and response (EDR) solutions to detect anomalous behavior indicative of exploitation attempts. 8. Consider sandboxing or application whitelisting for Adobe InCopy to prevent unauthorized code execution. These measures go beyond generic advice by focusing on the specific attack vector (malicious file opening) and the operational context of Adobe InCopy usage.
