CVE-2021-33580 (GCVE-0-2021-33580)

Vulnerability from cvelistv5

Severity ?

CWE

CWE-400 - Uncontrolled Resource Consumption

Summary

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.
