A vulnerability was found in OpenSSL 0.9.8h/0.9.8i/0.9.8j (Network Encryption Software). It has been declared as problematic. This vulnerability affects the function CMS_verify
. The manipulation with an unknown input leads to a improper authentication vulnerability. The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. As an impact it is known to affect integrity. CVE summarizes:
The CMS_verify function in OpenSSL 0.9.8h through 0.9.8j, when CMS is enabled, does not properly handle errors associated with malformed signed attributes, which allows remote attackers to repudiate a signature that originally appeared to be valid but was actually invalid.
The bug was discovered 03/25/2009. The weakness was shared 03/25/2009 (Website). The advisory is available at kb.bluecoat.com. This vulnerability was named CVE-2009-0591 since 02/13/2009. The exploitation appears to be difficult. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit.
It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 301 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 17764 (OpenSSL < 0.9.8k Signature Repudiation), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Web Servers and running in the context r. The commercial vulnerability scanner Qualys is able to test this issue with plugin 185073 (HP-UX Running OpenSSL Remote Denial of Service Vulnerability (HPSBUX02435)).
Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.
The vulnerability is also documented in the databases at X-Force (49432) and Tenable (17764). The entries 47384 and 47373 are related to this item.
