CVE-2023-31421 describes a critical vulnerability affecting Elastic products including Beats, Elastic Agent, APM Server, and Fleet Server when acting as TLS clients. The flaw allows these clients to connect to a server without fully validating its certificate if connecting via an IP address, specifically failing to check IP Subject Alternative Name (SAN) values, despite signature validation still occurring. This vulnerability carries a CVSS score of 7.5 (HIGH), indicating a network-based attack with low complexity that could lead to high confidentiality impact. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
