CVE-2023-34132Public exploitNetwork attack vector

Account takeover via client-side pass-the-hash authentication

Published Jul 13, 2023 · Updated Feb 13, 2025

Authentication weakness in SonicWall GMS 9.3.2-SP1 and earlier and Analytics 2.5.0.4-R7 and earlier allows pass-the-hash login. The client-side logon hashing algorithm accepts a stored password hash as sufficient authentication instead of requiring the underlying plaintext password. Remote attackers must first obtain a user hash; successful use grants that account's application privileges without revealing its password.
