CVE-2023-37177Public exploitNetwork attack vector

Unauthenticated code execution via injected export query

Published Feb 21, 2024 · Updated Aug 15, 2024

SQL injection in PMB 7.4.7 and earlier allows remote attackers to execute arbitrary code through export_z3950.php's query parameter. The endpoint accepts the untrusted query value without adequate SQL neutralization, but public sources do not identify the exact database function or statement. No authentication or user interaction is required, and successful injection can compromise application data and execute code in the server context.
