CVE-2011-5034
HIGHEPSS 100th pctlDescription
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.
CVSS v2 Vector
No CVSS vector data available.
Exploit Intelligence
Very high risk: more likely to be exploited than 100% of all known CVEs.
