CVE-2007-2165
NVD-CWE-OtherPublished: April 22, 2007· Updated: Jun 16, 2026
5.1
CVSS v3.1
Official Description
The Auth API in ProFTPD before 20070417, when multiple simultaneous authentication modules are configured, does not require that the module that checks authentication is the same as the module that retrieves authentication data, which might allow remote attackers to bypass authentication, as demonstrated by use of SQLAuthTypes Plaintext in mod_sql, with data retrieved from /etc/passwd.
Technical Analysis
CVE-2007-2165 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
