CVE-2022-29158Network attack vector

Service interruption via backtracking URL regex

Published Sep 2, 2022 · Updated Aug 3, 2024

Regular expression denial of service in Apache OFBiz 18.12.05 and earlier allows remote attackers to interrupt service via crafted URLs. UtilHttp.extractUrls applies Java's backtracking regular-expression engine to attacker-controlled URL text, permitting excessive processing; the fix substitutes linear-time RE2J matching. No authentication or user interaction is required, and the documented consequence is availability loss rather than data access or modification.
