Vulnerability from github – Published: 2022-05-24 19:11 – Updated: 2022-05-24 19:11

Details

User controlled request.getHeader("Referer"), request.getRequestURL() and request.getQueryString() are used to build and run a regex expression. The attacker doesn't have to use a browser and may send a specially crafted Referer header programmatically. Since the attacker controls the string and the regex pattern he may cause a ReDoS by regex catastrophic backtracking on the server side. This problem has been fixed in Roller 6.0.2.
