Deeper analysis
CVE-2022-29155 is a SQL injection vulnerability in the experimental back-sql backend of OpenLDAP slapd, affecting versions 2.x prior to 2.5.12 and 2.6.x prior to 2.6.2. The flaw arises from insufficient escaping of LDAP search filters, allowing a SQL statement to be injected during query processing and executed against the backend database.
An unauthenticated remote attacker can exploit the issue over the network by submitting a crafted LDAP search operation. Successful exploitation can result in full compromise of the confidentiality, integrity, and availability of the underlying data, consistent with the CVSS 9.8 rating and CWE-89 classification.
Advisories from Debian, NetApp, and OpenLDAP project references indicate that the issue is resolved by upgrading to the fixed releases 2.5.12 or 2.6.2, with corresponding package updates distributed through operating-system security channels.
The EPSS score rose from a low baseline to a peak of 0.2341, indicating that exploitation interest emerged after public disclosure and that the vulnerability warrants renewed attention.
