CVE-2025-23171

Estado: AnalizadaAlta (7.2)—

The Versa Director SD-WAN orchestration platform provides an option to upload various types of files. The Versa Director does not correctly limit file upload permissions. The UI appears not to allow file uploads but uploads still succeed. In addition, the Versa Director discloses the full filename of uploaded temporary files, including the UUID prefix. Insecure UCPE image upload in Versa Director allows an authenticated attacker to upload a webshell.

Exploitation Status:

Versa Networks is not aware of any reported instance where this vulnerability was exploited. Proof of concept for this vulnerability has been disclosed by third party security researchers.

La interfaz de usuario parece no permitir la carga de archivos, pero aun así se carga correctamente. Además, Versa Director revela el nombre completo de los archivos temporales cargados, incluido el prefijo UUID. La carga insegura de imágenes UCPE en Versa Director permite que un atacante autenticado cargue un webshell.

Soluciones alternativas o mitigación: No existen soluciones alternativas para deshabilitar la opción de la interfaz gráfica de usuario. Versa recomienda actualizar Director a una de las versiones de software corregidas."
