CVE-2022-29155· NVD / CVE Program· CNA mitre

In OpenLDAP 2.x before 2.5.12 and 2.6.x before 2.6.2, a SQL injection vulnerability exists in the experimental back-sql backend to slapd, vi

Noroxi assessment

Priority: Plan (action score 58/100)

  • 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: 64.4% (FIRST EPSS); higher than 99.2% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: openldap (Alpine:v3.15) 2.6.2-r0; openldap (Debian:10) 2.4.47+dfsg-3+deb10u7; openldap (Debian:11) 2.4.57+dfsg-3+deb11u1.

Add it to your regular patch cycle. Upgrade to openldap (Alpine:v3.15) 2.6.2-r0; openldap (Debian:10) 2.4.47+dfsg-3+deb10u7; openldap (Debian:11) 2.4.57+dfsg-3+deb11u1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In OpenLDAP 2.x before 2.5.12 and 2.6.x before 2.6.2, a SQL injection vulnerability exists in the experimental back-sql backend to slapd, via a SQL statement within an LDAP query. This can occur during an LDAP search operation when the search filter is processed, due to a lack of proper escaping.

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.
