CVE-2026-57878

Full vulnerability record from the local CVENow database.

Description

An unauthenticated stack-based buffer overflow vulnerability exists in thttpd in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when processing web request parameters in a specific request path. A remote attacker may exploit this vulnerability by sending a crafted HTTP request with overly long input, resulting in memory corruption, denial of service, or potentially arbitrary code execution.

La vulnerabilidad es causada por una comprobación de límites insuficiente al procesar parámetros de solicitud web en una ruta de solicitud específica. Un atacante remoto puede explotar esta vulnerabilidad al enviar una solicitud HTTP manipulada con una entrada excesivamente larga, lo que resulta en corrupción de memoria, denegación de servicio o potencialmente ejecución de código arbitrario."
