CVE-2022-30652 is an out-of-bounds write vulnerability (CWE-787) affecting Adobe InCopy versions 17.2 and earlier, as well as 16.4.1 and earlier. This vulnerability arises when the software improperly handles memory boundaries, allowing an attacker to write data outside the intended buffer limits. Such memory corruption can lead to arbitrary code execution within the context of the current user. Exploitation requires user interaction, specifically the victim opening a maliciously crafted InCopy file. Once opened, the malicious file triggers the out-of-bounds write, potentially enabling an attacker to execute arbitrary code, modify data, or cause application crashes. There are no known exploits in the wild as of the published date, and no official patches or updates have been linked in the provided information. The vulnerability is classified as medium severity by the vendor, reflecting the requirement for user interaction and the scope limited to the current user context rather than system-wide privileges.

For European organizations, the impact of CVE-2022-30652 primarily concerns confidentiality and integrity risks at the user level. Adobe InCopy is widely used in publishing, media, and creative industries, sectors that are significant in countries like Germany, France, the UK, and the Netherlands. Successful exploitation could allow attackers to execute arbitrary code, potentially leading to data theft, unauthorized modification of documents, or lateral movement within a compromised environment if combined with other vulnerabilities. However, since exploitation requires user interaction and the current user context limits privilege escalation, the threat is less severe than vulnerabilities allowing remote or privilege-escalated execution. Still, targeted attacks on media companies or creative agencies could disrupt workflows, cause reputational damage, or lead to intellectual property theft. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks, especially as threat actors often develop exploits for publicly disclosed vulnerabilities.

1. Immediate mitigation should focus on user awareness training to recognize and avoid opening suspicious or unsolicited InCopy files, especially from untrusted sources. 2. Implement strict email filtering and attachment scanning to reduce the likelihood of malicious files reaching end users. 3. Employ application whitelisting and sandboxing techniques for Adobe InCopy to limit the impact of any successful exploit. 4. Monitor for unusual application behavior or crashes that could indicate exploitation attempts. 5. Maintain up-to-date backups of critical documents to enable recovery in case of data corruption. 6. Regularly check Adobe’s official security advisories for patches or updates addressing this vulnerability and apply them promptly once available. 7. Consider network segmentation to isolate systems running Adobe InCopy from sensitive infrastructure to limit lateral movement potential. 8. Use endpoint detection and response (EDR) tools to detect anomalous code execution patterns related to this vulnerability.
