SurgeFTP weak password encryption could allow attackers to obtain passwords
|surgeftp-weak-password-encryption (6961)||Low Risk|
NetWin SurgeFTP could allow a remote attacker to obtain user passwords. The SurgeFTP password hashing algorithm uses a single fixed salting method, which limits the number of has values and causes some hashes to correspond to multiple passwords. A remote attacker can use this vulnerability to obtain user passwords, including the administrator password, using brute force password cracking techniques.
Upgrade to the latest version of SurgeFTP (2.0i or later), available from the SurgeFTP Web site. See References.
