CVE-2021-41139 Information

Description

Anuko Time Tracker is an open source web-based time tracking application written in PHP. When a logged on user selects a date in Time Tracker it is being passed on via the date parameter in URI. Because of not checking this parameter for sanity in versions prior to 1.19.30.5600 it was possible to craft the URI with malicious JavaScript use social engineering to convince logged on user to click on such link and have the attacker-supplied JavaScript to be executed in user’s browser. This issue is patched in version 1.19.30.5600. As a workaround one may introduce ttValidDbDateFormatDate function as in the latest version and add a call to it within the access checks block in time.php.
