CVE-2022-30653 is a security vulnerability identified in Adobe InCopy, specifically affecting versions 17.2 and earlier, as well as 16.4.1 and earlier. The vulnerability is classified as an out-of-bounds write (CWE-787), which occurs when a program writes data outside the boundaries of allocated memory. This can lead to memory corruption, potentially allowing an attacker to execute arbitrary code within the context of the current user. The exploitation vector requires user interaction, specifically the opening of a maliciously crafted InCopy file. When such a file is opened, the vulnerability can be triggered, enabling code execution that could compromise the confidentiality, integrity, and availability of the affected system. No public exploits have been reported in the wild to date, and no official patches or updates have been linked in the provided information. The vulnerability was reserved in May 2022 and publicly disclosed in June 2022. Given that Adobe InCopy is a professional writing and editing software widely used in publishing and media industries, the vulnerability poses a risk primarily to users in those sectors who handle untrusted or externally sourced InCopy files.

For European organizations, the impact of CVE-2022-30653 can be significant, particularly for those in the media, publishing, and creative industries where Adobe InCopy is commonly used. Successful exploitation could allow attackers to execute arbitrary code with the privileges of the current user, potentially leading to data theft, unauthorized modification of documents, or further network compromise if the user has elevated privileges. Since the vulnerability requires user interaction, social engineering or phishing campaigns could be leveraged to deliver malicious files. This could disrupt business operations, damage intellectual property, and lead to reputational harm. Additionally, organizations with weak endpoint security or insufficient user awareness training may be more vulnerable. The medium severity rating reflects the need for user action and the limited scope of impact to the current user context rather than system-wide compromise. However, in environments where users have administrative rights or where InCopy is integrated into larger workflows, the risk could be amplified.

To mitigate this vulnerability effectively, European organizations should: 1) Immediately verify and apply any available Adobe patches or updates for InCopy as soon as they are released. 2) Implement strict file handling policies that restrict opening InCopy files from untrusted or unknown sources. 3) Enhance user awareness training focused on recognizing phishing attempts and the risks of opening unsolicited files. 4) Employ endpoint protection solutions capable of detecting anomalous behavior related to memory corruption exploits. 5) Use application whitelisting to limit execution of unauthorized code. 6) Where possible, run Adobe InCopy with the least privilege necessary to reduce the impact of potential exploitation. 7) Monitor network and endpoint logs for unusual activity that could indicate exploitation attempts. 8) Consider sandboxing or isolating the InCopy application environment to contain potential exploits. These steps go beyond generic advice by focusing on operational controls tailored to the nature of the vulnerability and the typical usage patterns of Adobe InCopy.
