Movable Type Prior to Version 4.23 Unspecified Cross-Site Scripting Vulnerability

Movable Type Prior to Version 4.23 Unspecified Cross-Site Scripting Vulnerability

Movable Type is prone to an unspecified cross-site scripting vulnerability because the application fails to sufficiently sanitize user-supplied data.

An attacker can leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie-based authentication credentials and launch other attacks.

NOTE: This issue is different from the one described in BID 32604.

Versions prior to Movable Type 4.23 are affected.
