Ajenti URL "respond_error()" Cross-Site Scripting Vulnerability


Description   Omar Kurt has reported a vulnerability in Ajenti, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input appended to the URL after e.g. ajenti:static/resources.js or ajenti:static/resources.css is not properly sanitised in the "respond_error()" function (ajenti/routing.py) before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerability is reported in version 1.2.21.6. Prior versions may also be affected.
