CVE-2025-20359 is a medium-severity vulnerability affecting multiple Cisco products utilizing the Snort 3 HTTP Decoder. It stems from a buffer under-read during HTTP header MIME field parsing, allowing an unauthenticated, remote attacker to trigger a denial of service (DoS) or sensitive information disclosure. The vulnerability has a CVSS score of 6.5, indicating a network-based attack with low complexity and no user interaction required, potentially leading to a partial loss of confidentiality and availability. Currently, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), and it is not listed on the KEV catalog, suggesting limited active exploitation. Community discussion and media coverage are minimal, with only one mention and one article identified.
