EUVDB-ID: #VU44781

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2011-3189

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The crypt function in PHP 5.3.7, when the MD5 hash type is used, returns the value of the salt argument instead of the hashed string, which might allow remote attackers to bypass authentication via an arbitrary password, a different vulnerability than CVE-2011-2483.
