Cisco Bug: CSCtb70849 - MARS uses MD5 signed certificate instead of SHA1
Jun 30, 2015
- Cisco Security Monitoring, Analysis and Response System
Known Affected Releases
Symptom: The remote service uses an SSL certificate that has been signed using a cryptographically weak hashing algorithm - MD2, MD4, or MD5. These algorithms are known to be vulnerable to collision attacks. In theory, an attacker could leverage this weakness to generate another certificate with the same digital signature, which could allow him to masquerade as the affected service. Conditions: Mars devices running 6.x. The SSL certificate of the CSMARS application was signed using weak hash algorithms i.e. MD5 instead of SHA1 causing risk of possible security breach due to the inherent weaknesses of an MD5 RSA signed certificate.
