AI-suggested
Immediate upgrade to Faction version 1.7.1 or later is the primary mitigation step to remediate this vulnerability. Until patching is possible, organizations should restrict network access to the /portal/AppStoreDashboard endpoint using firewalls or web application firewalls (WAFs) to prevent unauthenticated access. Implement strict access controls and network segmentation to isolate systems running Faction from untrusted networks. Monitor logs and network traffic for unusual activity related to extension uploads or lifecycle hook invocations. Employ application-layer intrusion detection systems to detect attempts to exploit this vulnerability. Conduct regular audits of installed extensions to identify and remove any unauthorized or suspicious components. Educate security teams about this vulnerability to ensure rapid detection and response. Finally, consider deploying endpoint detection and response (EDR) solutions on servers hosting Faction to detect and contain potential exploitation attempts.
Description
FACTION is a PenTesting Report Generation and Collaboration Framework. Prior to version 1.7.1, an extension execution path in Faction’s extension framework permits untrusted extension code to execute arbitrary system commands on the server when a lifecycle hook is invoked, resulting in remote code execution (RCE) on the host running Faction. Due to a missing authentication check on the /portal/AppStoreDashboard endpoint, an attacker can access the extension management UI and upload a malicious extension without any authentication, making this vulnerability exploitable by unauthenticated users. This issue has been patched in version 1.7.1.
