CVE-2024-7544

oFono SimToolKit Heap-based Buffer Overflow Privilege Escalation Vulnerability. This vulnerability allows local attackers to execute arbitrary code on affected installations of oFono. An attacker must first obtain the ability to execute code on the target modem in order to exploit this vulnerability. The specific flaw exists within the parsing of STK command PDUs. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-23457.

Summary		(es) Vulnerabilidad de escalada de privilegios de desbordamiento de búfer basado en montón de oFono SimToolKit. Esta vulnerabilidad permite a atacantes locales ejecutar código arbitrario en las instalaciones afectadas de oFono. Un atacante primero debe obtener la capacidad de ejecutar código en el módem de destino para poder aprovechar esta vulnerabilidad. La falla específica existe en el análisis de las PDU de comando STK. El problema se debe a la falta de una validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos en un búfer basado en montón. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la cuenta de servicio. Era ZDI-CAN-23457.
