Detailsinfo

A vulnerability, which was classified as critical, has been found in OpenSSL FIPS Object Module 1.1.1 (Network Encryption Software). This issue affects some unknown processing of the component OpenSSL. The manipulation with an unknown input leads to a cryptographic issue vulnerability. Using CWE to declare the problem leads to CWE-310. Impacted is confidentiality, and integrity. The summary by CVE is:

The PRNG implementation for the OpenSSL FIPS Object Module 1.1.1 does not perform auto-seeding during the FIPS self-test, which generates random data that is more predictable than expected and makes it easier for attackers to bypass protection mechanisms that rely on the randomness.

The weakness was shared 12/01/2007 by Geoff as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org. The identification of this vulnerability is CVE-2007-5502 since 10/17/2007. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1600 according to MITRE ATT&CK.

It is declared as proof-of-concept.

Applying a patch is able to eliminate this problem.

The vulnerability is also documented in the databases at X-Force (38796), SecurityFocus (BID 26652†), Secunia (SA27859†) and SecurityTracker (ID 1019029†). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
