Pukiwiki MT4i Plugin is prone to multiple unspecified cross-site-scripting vulnerabilities because it fails to properly sanitize user-supplied input.
An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and to launch other attacks.
MT4i Plugin 3.0 is vulnerable; other versions may also be affected.
Proof of Concept and Security Exploits
Attackers can exploit these issues by enticing an unsuspecting victim to follow a malicious URI.
