CVE-2025-48057 is a critical certificate validation vulnerability affecting Icinga 2 versions prior to 2.12.12, 2.13.12, and 2.14.6, specifically when built with OpenSSL older than 1.1.0. An attacker can exploit a flaw in the VerifyCertificate() function to trick Icinga 2 into accepting a malicious certificate request as a valid renewal, thereby obtaining a legitimate certificate for impersonation. This vulnerability carries a CVSS score of 9.8 (CRITICAL) due to its network-based attack vector, low complexity, and high impact on confidentiality, integrity, and availability. While there is no known active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered some community discussion, indicating awareness within the cybersecurity community.
