AI-suggested
Until Adobe releases an official patch, organizations should implement several specific mitigations: 1) Enforce strict email and file attachment filtering to block or quarantine suspicious InCopy files from untrusted sources. 2) Educate users about the risks of opening unsolicited or unexpected InCopy documents, emphasizing caution with files from unknown senders. 3) Employ application whitelisting and sandboxing to restrict InCopy’s ability to execute arbitrary code or access critical system resources. 4) Monitor endpoint behavior for unusual activity related to InCopy processes, such as unexpected network connections or file modifications. 5) Use endpoint detection and response (EDR) tools to detect exploitation attempts and respond rapidly. 6) Limit user privileges to the minimum necessary to reduce the impact of potential exploitation. 7) Regularly back up critical data to enable recovery in case of compromise. Once Adobe releases patches, prioritize immediate deployment across all affected systems.
Description
InCopy versions 20.4, 19.5.4 and earlier are affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
