CVE-2009-2166· NVD / CVE Program· CNA mitre

Absolute path traversal vulnerability in cvs.php in OCS Inventory NG before 1.02.1 on Unix allows remote attackers to read arbitrary files v

Noroxi assessment

Priority: Monitor (action score 21/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 3.1% (FIRST EPSS); higher than 87.7% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: ocsinventory-server (Debian:12) 1.02.1-1.

Low priority for now. Upgrade to ocsinventory-server (Debian:12) 1.02.1-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Absolute path traversal vulnerability in cvs.php in OCS Inventory NG before 1.02.1 on Unix allows remote attackers to read arbitrary files via a full pathname in the log parameter.

No credits in the CNA record.

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

CVSS vector

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

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

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

Fixed

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