EUVDB-ID: #VU44204

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2012-0770

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Adobe ColdFusion 8.0, 8.0.1, 9.0, and 9.0.1 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. Per: http://cwe.mitre.org/data/definitions/407.html 'CWE-407: Algorithmic Complexity'

Mitigation

Install update from vendor's website.

Vulnerable software versions

ColdFusion: 8.0 - 9.0.1
