CVE-2023-23749Network attack vector

LDAP directory disclosure via unsanitized username

Published Jan 17, 2023 · Updated Apr 4, 2025

LDAP injection in miniOrange LDAP Integration 5.0.2 allows remote attackers to read arbitrary LDAP data via a crafted username. The extension fails to sanitize the username POST parameter before using it in an LDAP query, so injected filter syntax changes the query scope. No authentication or user interaction is required, and successful exploitation discloses directory entries without altering them.
