Title: ikiwiki Blank Password Authentication Bypass Vulnerability
Severity: MODERATE
Description:
The 'ikiwiki' program is a wiki compiler.
The software is prone to an authentication-bypass vulnerability that occurs when it is configured to use the 'openid' and 'passwordauth' plugins. Specifically, the vulnerability occurs when processing login requests with a blank password.
An attacker can exploit this issue to gain access to accounts that are associated with an 'openid'.
Successfully exploiting this issue will allow attackers to gain unauthorized access to the affected application.
Versions between ikiwiki 1.34 and 2.47 are vulnerable.
