CVE-2025-62786

Full vulnerability record from the local CVENow database.

Description

Wazuh is a free and open source platform used for threat prevention, detection, and response. A heap-based out-of-bounds WRITE occurs in decode_win_permissions, resulting in writing a NULL byte 2 bytes before the start of the buffer allocated to decoded_it. A compromised agent can potentially leverage this issue to perform remote code execution, by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can leverage this issue to potentially achieve remote code execution on the wazuh manager (the exploitability of this vulnerability depends on the specifics of the respective heap allocator). This vulnerability is fixed in 4.10.2.

Una escritura fuera de límites basada en el heap ocurre en decode_win_permissions, resultando en la escritura de un byte NULL 2 bytes antes del inicio del búfer asignado a decoded_it. Un agente comprometido puede potencialmente aprovechar este problema para realizar ejecución remota de código, enviando un mensaje especialmente diseñado al gestor de Wazuh. Un atacante que sea capaz de diseñar y enviar un mensaje de agente al gestor de Wazuh puede aprovechar este problema para potencialmente lograr ejecución remota de código en el gestor de Wazuh (la explotabilidad de esta vulnerabilidad depende de las especificidades del asignador de heap respectivo). Esta vulnerabilidad está corregida en 4.10.2."
