GoAhead WebServer Multiple Script Insertion Vulnerabilities


Description   Multiple vulnerabilities have been discovered in GoAhead WebServer, which can be exploited by malicious people to conduct script insertion attacks.
1) Input passed via the "group" POST parameter to goform/AddGroup (when "ok" is set to "OK") when adding a group is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.
2) Input passed via the "url" POST parameter to goform/AddAccessLimit (when "ok" is set to "OK") when adding an access limit is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.
3) Input passed via the "user" POST parameter to goform/AddUser (when "ok" is set to "OK") when adding a user is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.
The vulnerabilities are confirmed in version 2.1.8. Prior versions may also be affected.
