A vulnerability in the RADIUS authentication module of Cisco Policy Suite could allow an unauthenticated, remote attacker to be authorized a

A vulnerability in the RADIUS authentication module of Cisco Policy Suite could allow an unauthenticated, remote attacker to be authorized as a subscriber without providing a valid password; however, the attacker must provide a valid username. The vulnerability is due to incorrect RADIUS user credential validation. An attacker could exploit this vulnerability by attempting to access a Cisco Policy Suite domain configured with RADIUS authentication. An exploit could allow the attacker to be authorized as a subscriber without providing a valid password. This vulnerability affects the Cisco Policy Suite application running a release prior to 13.1.0 with Hotfix Patch 1 when RADIUS authentication is configured for a domain. Cisco Policy Suite Release 14.0.0 is also affected, as it includes vulnerable code, but RADIUS authentication is not officially supported in Cisco Policy Suite Releases 14.0.0 and later. Cisco Bug IDs: CSCvg40124.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Weakness class (CWE)

CWE-287 · Improper Authentication

CVSS vector

CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N

nvd-primary

Root cause

Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.

The bug in code

The whole CWE-287 class

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

Vulnerable

ts
app.use("/admin", requireSession, adminRouter);
// Route added later skips the middlewareapp.post("/admin-api/config", updateConfig);

Fixed

ts
const admin = express.Router();admin.use(requireSession, requireRole("admin"));
admin.post("/config", updateConfig);app.use("/admin", admin);
