Priority: Monitor (action score 25/100)

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: 1.9% (FIRST EPSS); higher than 80.6% of all records.
Fixed version: python-django (Debian:12) 1.6.6-1; python-django (Debian:6.0) 1.2.3-3+squeeze11; python-django (Debian:7) 1.4.5-1+deb7u8.

Low priority for now. Upgrade to python-django (Debian:12) 1.6.6-1; python-django (Debian:6.0) 1.2.3-3+squeeze11; python-django (Debian:7) 1.4.5-1+deb7u8 or later.

Weakness class (CWE)

CWE-287 · Improper Authentication

CVSS vector

AV:N/AC:M/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

1app.use("/admin", requireSession, adminRouter);
2

3// Route added later skips the middleware
4app.post("/admin-api/config", updateConfig);

Fixed

1const admin = express.Router();
2admin.use(requireSession, requireRole("admin"));
3

4admin.post("/config", updateConfig);
5app.use("/admin", admin);
