CVE-2016-8856: Foxit Reader for Mac 2.1.0.0804 and earlier and Foxit Reader for Linux 2.1.0.0805 and earlier suffered from...

Foxit Reader for Mac 2.1.0.0804 and earlier and Foxit Reader for Linux 2.1.0.0805 and earlier suffered from a vulnerability where weak file permissions could be exploited by attackers to execute arbitrary code. After the installation, Foxit Reader's core files were world-writable by default, allowing an attacker to overwrite them with backdoor code, which when executed by privileged user would result in Privilege Escalation, Code Execution, or both.

Security readout for executives and security teams

This issue affects older Foxit Reader installs on macOS and Linux. The application installed important files with permissions that allowed any local user to modify them. If a privileged user later ran Foxit Reader, tampered files could execute attacker-controlled code with higher privileges. Exposure is most likely on legacy macOS or Linux endpoints still running the affected Foxit Reader versions. The source bundle does not identify Windows exposure, supported fixed versions, package names, or default install paths. Treat this as a legacy endpoint hygiene risk with privilege escalation potential. Prioritize removal or upgrade where affected Foxit Reader versions remain on shared workstations, administrator systems, or Linux desktops used for sensitive operations. Mitigation focus: Check Foxit security bulletins for the vendor-confirmed fixed or supported version.; Remove or upgrade affected Foxit Reader for Mac and Linux installations.; Avoid privileged execution of affected Foxit Reader builds..
