Name of the Vulnerable Software and Affected Versions: Foxit PhantomPDF version 9.7.0.29478

Description: This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the handling of the DuplicatePages command of the communication API, resulting from the lack of proper validation of user-supplied data, which can lead to a type confusion condition. An attacker can leverage this to execute code in the context of the current process.

Recommendations: For Foxit PhantomPDF version 9.7.0.29478, as a temporary workaround, consider disabling the DuplicatePages command until a patch is available. Restrict access to the communication API to minimize the risk of exploitation. Avoid using the DuplicatePages command in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
