CVE-2024-21793Public exploitNetwork attack vector

Password-hash disclosure via injectable OData login filter

Published May 8, 2024 · Updated Sep 18, 2025

OData injection in F5 BIG-IP Next Central Manager 20.0.1 through 20.1.0 allows remote attackers to disclose administrator password hashes. The unauthenticated /api/login handler inserts the username value into an OData filter, allowing crafted Boolean expressions and startswith() tests to act as an error oracle over stored password hashes. The management API must be reachable and LDAP authentication enabled; exploitation discloses hashes but does not directly alter data or interrupt service.
