Browse all 3365 CVE security advisories affecting Cisco. AI-powered Chinese analysis, POCs, and references for each vulnerability.

Cisco Systems operates as a global leader in networking hardware, software, and telecommunications services, providing critical infrastructure for enterprise connectivity and cloud security. With over 3,000 recorded CVEs, the company’s attack surface is extensive, reflecting the complexity of its diverse product portfolio. Historically, vulnerabilities frequently involve remote code execution (RCE), cross-site scripting (XSS), and privilege escalation flaws, often stemming from legacy protocols or complex configuration interfaces. Notable incidents include the 2023 supply chain compromise affecting the Cisco AnyConnect Secure Mobility Client, which allowed attackers to bypass authentication mechanisms. These breaches highlight risks associated with widely deployed endpoint security agents. The sheer volume of disclosed issues underscores the challenges inherent in maintaining security across such a vast ecosystem of interconnected devices and software solutions, requiring rigorous patch management and continuous monitoring to mitigate potential exploitation by threat actors targeting critical network infrastructure.
