The random-number generator on Cisco Small Business RV routers 4.x and SA500 security appliances 2.2.07 does not have sufficient entropy, which makes it easier for remote attackers to determine a TLS key pair via unspecified computations upon handshake key-exchange data, aka Bug ID CSCus15224.
CVE-2015-6418 is a security vulnerability that . Impacting 7 products from cisco, from cisco, from cisco and 4 others, organizations running these solutions should prioritize assessment and patching.
First disclosed in 2015, this vulnerability was reported during a period defined by widespread IoT adoption challenges, mobile security concerns, and the emergence of advanced persistent threat (APT) techniques. Contemporary mitigation strategies focused on secure development practices and third-party component vetting.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For cisco's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
