YesWiki versions before 4.6.7 have a reflected cross-site scripting (XSS) vulnerability in the mail handler's field parameter. This flaw allows unauthenticated attackers to inject malicious scripts by crafting links that manipulate the ajax-mail-form action attribute, potentially executing JavaScript in the browsers of users who click these links.
AI Analysis
Technical Summary
The vulnerability in YesWiki prior to version 4.6.7 is a reflected XSS issue where the 'field' parameter in the mail handler is not properly sanitized. Attackers can exploit this by sending crafted URLs that break out of the ajax-mail-form action attribute, causing arbitrary JavaScript execution in victims' browsers. This vulnerability requires user interaction (clicking a malicious link) and does not require authentication.
Potential Impact
Successful exploitation can lead to limited confidentiality and integrity impacts by executing arbitrary JavaScript in the context of the victim's browser session. This could allow attackers to steal session tokens, perform actions on behalf of the user, or manipulate the user interface. There is no impact on availability reported.
Mitigation Recommendations
A fix is available in YesWiki version 4.6.7. Users should upgrade to version 4.6.7 or later to remediate this vulnerability. No vendor advisory or patch link was provided, so verify the upgrade availability from official YesWiki sources.
