A certain Red Hat patch for SquirrelMail 1.4.8 sets the same SQMSESSID cookie value for all sessions, which allows remote authenticated user

Noroxi assessment

Priority: Monitor (action score 27/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.6% (FIRST EPSS); higher than 76.4% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: squirrelmail (Red Hat:enterprise_linux:3::as) 0:1.4.8-9.el3; squirrelmail (Red Hat:enterprise_linux:4::as) 0:1.4.8-5.el4_7.3; squirrelmail (Red Hat:enterprise_linux:5::client_workstation) 0:1.4.8-5.el5_2.3.

Low priority for now. Upgrade to squirrelmail (Red Hat:enterprise_linux:3::as) 0:1.4.8-9.el3; squirrelmail (Red Hat:enterprise_linux:4::as) 0:1.4.8-5.el4_7.3; squirrelmail (Red Hat:enterprise_linux:5::client_workstation) 0:1.4.8-5.el5_2.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A certain Red Hat patch for SquirrelMail 1.4.8 sets the same SQMSESSID cookie value for all sessions, which allows remote authenticated users to access other users' folder lists and configuration data in opportunistic circumstances by using the standard webmail.php interface. NOTE: this vulnerability exists because of an incorrect fix for CVE-2008-3663.

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.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Weakness class (CWE)

CWE-287 · Improper Authentication

CVSS vector

AV:N/AC:L/Au:S/C:P/I:P/A:P

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);

Attack context

MITRE CAPEC attack patterns and ATT&CK techniques for this weakness class (CWE). A starting point for detection rules and threat hunting.
