CVE-2022-24851: Stored XSS and path traversal in LDAPAccountManager/lam

Noroxi assessment

Priority: Monitor (action score 19/100)

  • 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: 1.1% (FIRST EPSS); higher than 65.8% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: LDAPAccountManager lam 7.9.1.
  • Severity is disputed: the assigning authority (CNA) scores it 8.1, NVD 4.8.

Low priority for now. Upgrade to LDAPAccountManager lam 7.9.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

LDAP Account Manager (LAM) is an open source web frontend for managing entries stored in an LDAP directory. The profile editor tool has an edit profile functionality, the parameters on this page are not properly sanitized and hence leads to stored XSS attacks. An authenticated user can store XSS payloads in the profiles, which gets triggered when any other user try to access the edit profile page. The pdf editor tool has an edit pdf profile functionality, the logoFile parameter in it is not properly sanitized and an user can enter relative paths like ../../../../../../../../../../../../../usr/share/icons/hicolor/48x48/apps/gvim.png via tools like burpsuite. Later when a pdf is exported using the edited profile the pdf icon has the image on that path(if image is present). Both issues require an attacker to be able to login to LAM admin interface. The issue is fixed in version 7.9.1.

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.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

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.

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.

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

Vulnerable

Fixed

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