Ariko-Security has discovered multiple vulnerabilities in Oxwall, which can be exploited by malicious people to conduct cross-site scripting attacks.
1) Input passed via the "month" parameter to blogs/user/username (when "username" is a valid username) is not properly sanitised 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.
Successful exploitation of this vulnerability requires that the Blogs module is enabled.
2) Input passed via the "email", "username", "repeatPassword", "password", "realname", and "captchaField" POST parameters to join is not properly sanitised 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.
3) Input passed via the "form_name" POST parameter to join is not properly sanitised 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 vulnerabilities are confirmed in version 1.4.0. Other versions may also be affected.
