Vulnerability CVE-2012-0193 - CERT Civis.Net

Vulnerability Name:

CVE-2012-0193 (CCN-72298)

Assigned:

2011-12-14

Published:

2012-01-17

Updated:

2012-01-27

Summary:

IBM WebSphere Application Server (WAS) 6.0 through 6.0.2.43, 6.1 before 6.1.0.43, 7.0 before 7.0.0.23, and 8.0 before 8.0.0.3 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:
