CyberRota Analysis
AI-GeneratedThe vulnerability in Apache CXF's FIQL query parser allows an attacker to craft a query that can exhaust CPU resources by causing the parser to process excessively long strings without operators. This can lead to degraded performance or denial of service, impacting the availability of the application. Organizations using affected versions should prioritize upgrading to versions 4.2.4, 4.1.9, or 3.6.13 to mitigate this risk.
Original NVD Description
Apache CXF's FIQL query parser has a vulnerability in how it searches for operators in query expressions. The search pattern can get stuck trying many combinations when it encounters a long string without an operator, causing the parser to consume excessive CPU time. An attacker can send a crafted query to make the server use up CPU resources, potentially slowing down or stopping other requests. The fix was to limit FIQL expressions to 4 KiB by default, preventing attackers from sending extremely long inputs while still allowing normal queries. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.
