CVE-2024-37393Public exploitNetwork attack vector

Active Directory data exfiltration via LDAP injection

Published Jun 10, 2024 · Updated Aug 2, 2024

LDAP injection in SecurEnvoy MFA before 9.4.514 allows remote attackers to exfiltrate Active Directory data through /secserver. The DESKTOP service passes improperly validated HTTP input into LDAP queries, allowing crafted filter syntax to change directory lookups. No authentication or user interaction is required, and exposed attributes can include the cleartext ms-Mcs-AdmPwd LAPS password.
