GHSA-v3h8-rw48-h4gr · Severity: high · Ecosystem: maven — Apache Geronimo Hash Collisions Cause DoS
Apache Geronimo 2.2.1 and earlier computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters. NOTE: this might overlap CVE-2011-4461.
Conclusion & alert: CVE-2011-5034 is rated High Exploit Risk (82.8/100): CVSS High severity, with high exploitation likelihood (EPSS 73.34%, 99th percentile). Core evidence: 1 public exploit reference(s) are indexed (Exploit-DB). EPSS rose +2.03% over the last day, indicating growing attacker interest. Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
