Se ha identificado una vulnerabilidad en Simcenter Femap (Todas las versiones anteriores a V2022.1.1). La aplicación afectada contiene una vulnerabilidad de desbordamiento de búfer en la región stack de la memoria al analizar archivos BDF especialmente diseñados. Esto podría permitir a un atacante ejecutar código en el contexto del proceso actual. (ZDI-CAN-15061)

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens Simcenter Femap. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of BDF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
