AnalysisAI
Stored cross-site scripting in Apache Roller 6.1.5 lets an unauthenticated remote attacker post a comment containing a javascript: URI that survives HTML comment formatting and executes in the browser of any visitor who clicks the crafted link. Exploitation is gated by a non-default configuration - the site must enable HTML in comments (users.comments.htmlenabled=true) and use the HTMLSubset comment formatter - and by required user interaction, while comment moderation, where enabled, delays publication of the malicious comment. …
