Summary

anuko/timetracker is an, open source time tracking system. In affected versions Time Tracker uses browser_today hidden control on a few pages to collect the today's date from user browsers. Because of not checking this parameter for sanity in versions prior to 1.19.30.5601, it was possible to craft an html form with malicious JavaScript, use social engineering to convince logged on users to execute a POST from such form, and have the attacker-supplied JavaScript to be executed in user's browser. This has been patched in version 1.19.30.5600. Upgrade is recommended. If it is not practical, introduce ttValidDbDateFormatDate function as in the latest version and add a call to it within the access checks block.
