CVE-2024-33868Network attack vector

LDAP query manipulation via unsanitized control characters

Published May 14, 2024 · Updated Feb 13, 2025

LDAP injection in linqi before 1.4.0.1 on Windows allows remote attackers to manipulate directory queries through user input. The Windows LDAP query handling fails to sufficiently sanitize special LDAP control characters before processing user-supplied values. Reachability requires enabled LDAP integration and a configured Active Directory connection; published material does not identify the exposed input or resulting directory operation.
