Descriptions

A vulnerability has been identified in Parasolid V33.1 (All versions < V33.1.262), Parasolid V34.0 (All versions < V34.0.252), Parasolid V34.1 (All versions < V34.1.242), Parasolid V35.0 (All versions < V35.0.161), Simcenter Femap V2022.1 (All versions < V2022.1.3), Simcenter Femap V2022.2 (All versions < V2022.2.2). The affected application contains an out of bounds write past the end of an allocated buffer while parsing specially crafted X_T files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-17292)

Se ha identificado una vulnerabilidad en Parasolid versiones V33.1 (Todas las versiones anteriores a V33.1.262), Parasolid versiones V34.0 (Todas las versiones anteriores a V34.0.252), Parasolid versiones V34.1 (Todas las versiones anteriores a V34.1.242), Parasolid versiones V35.0 (Todas las versiones anteriores a V35.0.161), Simcenter Femap versiones V2022.1 (Todas las versiones anteriores a V2022.1.3), Simcenter Femap versiones V2022.2 (Todas las versiones anteriores a V2022.2.2). La aplicación afectada contiene una escritura fuera de límites más allá del final de un búfer asignado mientras analiza archivos X_T especialmente diseñados. Esto podría permitir a un atacante ejecutar código en el contexto del proceso actual. (ZDI-CAN-17292)

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 X_T files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process.
