Vulnerability CVE-2011-4462 - CERT Civis.Net

Vulnerability Name:

CVE-2011-4462 (CCN-72018)

Assigned:

2011-12-28

Published:

2011-12-28

Updated:

2017-08-29

Summary:

Plone 4.1.3 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.

CVSS v3 Severity:
