HighCVSS 7.5 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

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: 4% (FIRST EPSS); higher than 90.7% of all records.
No special conditions are required; it is repeatable.
Fixed version: php5 (Debian:4.0) 5.2.0+dfsg-8+etch15; php5 (Debian:5.0) 5.2.6.dfsg.1-1+lenny3, 5.2.6.dfsg.1-1+lenny2; php (Red Hat:rhel_application_stack:2) 0:5.2.6-4.el5s2.

Low priority for now. Upgrade to php5 (Debian:4.0) 5.2.0+dfsg-8+etch15; php5 (Debian:5.0) 5.2.6.dfsg.1-1+lenny3, 5.2.6.dfsg.1-1+lenny2; php (Red Hat:rhel_application_stack:2) 0:5.2.6-4.el5s2 or later.

Weakness class (CWE)

CWE-22 · Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSS vector

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

nvd-primary

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.

The bug in code

The whole CWE-22 class

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

Vulnerable

1const file = path.join(ROOT, req.query.name);
2res.sendFile(file);

Fixed

1const file = path.resolve(ROOT, req.query.name);
2if (!file.startsWith(ROOT + path.sep)) {
3  return res.sendStatus(400);
4}
5res.sendFile(file);
