CVE-2017-12425 is a Denial-of-Service vulnerability affecting Varnish HTTP Cache versions 4.0.1 through 4.0.4, 4.1.0 through 4.1.7, 5.0.0, and 5.1.0 through 5.1.2. An integer overflow in the varnishd source code allows an unauthenticated attacker to send crafted requests, triggering an assert and causing the worker process to crash and restart, effectively clearing the cache. This vulnerability has a CVSSv3 score of 7.5 (High), indicating a network-exploitable attack with low complexity and high impact on availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
