FKIE_CVE-2025-43960

Vulnerability from fkie_nvd - Published: 2025-08-25 14:15 - Updated: 2025-09-12 20:16
Severity ?
8.6 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L
Summary
Adminer 4.8.1, when using Monolog for logging, allows a Denial of Service (memory consumption) via a crafted serialized payload (e.g., using s:1000000000), leading to a PHP Object Injection issue. Remote, unauthenticated attackers can trigger this by sending a malicious serialized object, which forces excessive memory usage, rendering Adminer’s interface unresponsive and causing a server-level DoS. While the server may recover after several minutes, multiple simultaneous requests can cause a complete crash requiring manual intervention.

Atacantes remotos no autenticados pueden desencadenar esto enviando un objeto serializado malicioso, lo que fuerza un uso excesivo de memoria, bloqueando la interfaz de Adminer y provocando un ataque de denegaci\u00f3n de servicio (DoS) a nivel de servidor. Si bien el servidor puede recuperarse despu\u00e9s de varios minutos, m\u00faltiples solicitudes simult\u00e1neas pueden provocar un bloqueo completo que requiera intervenci\u00f3n manual."
