Summary
In OpenLDAP 2.x before 2.5.12 and 2.6.x before 2.6.2, there is a SQL injection vulnerability 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.
Risk Assessment
An attacker could exploit this vulnerability to execute unauthorized SQL queries, potentially leading to confidentiality or integrity breaches of the database.
Recommendation
It is recommended to immediately upgrade OpenLDAP to version 2.5.12 or later (for the 2.5 series) and 2.6.2 or later (for the 2.6 series).
