CVE-2011-4858
Overview
CVE-2011-4858 is a known-severity vulnerability affecting apache tomcat. It was published on January 5, 2012.
Technical Description
Apache Tomcat before 5.5.35, 6.x before 6.0.35, and 7.x before 7.0.23 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.
Remediation
Check the references section for vendor advisories and patches from apache. Update tomcat to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
