Summary
CVE-2025-66022 is a critical-severity Improper Authentication (CWE-287) vulnerability in Owasp Faction. Its CVSS base score is 9.6 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Supply Chain Compromise (T1195); ranked at the 49th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-24 (Access Control Decisions) and AC-25 (Reference Monitor) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-66022 is a remote code execution (RCE) vulnerability in FACTION, a PenTesting Report Generation and Collaboration Framework. Prior to version 1.7.1, the extension execution path in Faction's extension framework allows untrusted extension code to execute arbitrary system commands on the server hosting Faction when a lifecycle hook is invoked. This flaw stems from improper authentication and access controls, specifically a missing authentication check on the /portal/AppStoreDashboard endpoint, which exposes the extension management UI.
Unauthenticated attackers can exploit this vulnerability over the network by accessing the unauthenticated endpoint to upload a malicious extension. Once uploaded, invoking a lifecycle hook triggers the execution of arbitrary system commands, achieving full RCE on the Faction host. The CVSS v3.1 base score of 9.6 (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H) reflects its high severity, with low attack complexity, no privileges required, user interaction needed, and changed scope impacting confidentiality, integrity, and availability. Associated CWEs include CWE-287 (Improper Authentication), CWE-829 (Inclusion of Functionality from Untrusted Control Sphere), and CWE-862 (Missing Authorization).
The issue has been addressed in FACTION version 1.7.1, as detailed in the project's GitHub security advisory (GHSA-xr72-2g43-586w) and the patching commit (c6389f1c76175b7c1c68d1a87b389311b16c62c3). Security practitioners should upgrade to 1.7.1 or later and review access to extension management endpoints.

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…
more
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.

Mitigating Controls (NIST 800-53 r5) AI
AC-3 directly requires enforcement of authorization decisions on every access request, structurally eliminating missing authorization checks.
Mandates unique identification and authentication of organizational users before access, directly stopping improper authentication.
Requires unique identification and authentication of devices before establishing connections, preventing unauthenticated device claims.
Mandates unique identification and authentication of non-organizational users, directly addressing the weakness for external actors.
AC-24 mandates that access control decisions are applied to each request, preventing bypass of authorization logic.
AC-25 requires a tamperproof, always-invoked reference monitor that ensures authorization checks cannot be omitted.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Requiring authentication methods whose strength matches the sensitivity of the data and mandating multi-factor authentication directly blocks attempts to access resources without proving identity.
Verifying user identity before issuing replacement credentials and forcing changes after compromise reduces the likelihood that authentication bypass can be achieved through stolen or weak credentials.
By requiring suppliers to propagate security requirements and to disclose component provenance, the control limits the inclusion of functionality obtained from untrusted third-party sources without oversight.
Requiring authentication and credentials before any access occurs eliminates the absence of authorization checks that would otherwise allow an unauthenticated actor to reach protected resources.
Requiring formal authorization of every access request before rights are granted ensures that checks for required permissions are performed, preventing missing authorization checks from being introduced.
Mandating segregated approval and oversight for non-human identities reduces the chance that weak or orphaned credentials can be exploited for unauthorized authentication.
