CVE-2026-5463
pymetasploit3 - Command Injection via Newline Injection in console.run_module_with_output()
Description
Command injection vulnerability in console.run_module_with_output() in pymetasploit3 through version 1.0.6 allows attackers to inject newline characters into module options such as RHOSTS. This breaks the intended command structure and causes the Metasploit console to execute additional unintended commands, potentially leading to arbitrary command execution and manipulation of Metasploit sessions.

Action Type Old Value New Value Added Translation Title: pymetasploit3 de Dan McInerney, Description: Vulnerabilidad de inyección de comandos en console.run_module_with_output() en pymetasploit3 hasta la versión 1.0.6 permite a los atacantes inyectar caracteres de nueva línea en opciones de módulo como RHOSTS. Esto rompe la estructura de comandos prevista y hace que la consola de Metasploit ejecute comandos adicionales no deseados, lo que podría llevar a la ejecución arbitraria de comandos y a la manipulación de sesiones de Metasploit. -
