Multiple vulnerabilities have been discovered in Collabtive, which can be exploited by malicious users to conduct script insertion and SQL injection attacks.
1) Input passed via the "name" POST parameter to managetask.php, managemilestone.php, and manageproject.php (when "action" is set to "edit" and "id" is set) 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 if malicious data is viewed.
2) Input passed via the "name", "company", "web", "tel1", "tel2", "address1", "country", and "state" POST parameters to managemilestone.php (when "action" is set to "add" and "id" is set) 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 if malicious data is viewed.
3) Input passed via the "id" parameter to managetimetracker.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The vulnerabilities are confirmed in version 1.1. Prior versions may also be affected.
