Descriptions

A vulnerability has been identified in Parasolid V34.0 (All versions < V34.0.252), Parasolid V34.0 (All versions >= V34.0.252 < V34.0.254), Parasolid V34.1 (All versions < V34.1.242), Parasolid V34.1 (All versions >= V34.1.242 < V34.1.244), Parasolid V35.0 (All versions < V35.0.170), Parasolid V35.0 (All versions >= V35.0.170 < V35.0.184), Simcenter Femap (All versions < V2023.1). The affected application contains an out of bounds read past the end of an allocated structure while parsing specially crafted X_T files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-17745)

Se ha identificado una vulnerabilidad en Parasolid V34.0 (Todas las versiones &lt; V34.0.252), Parasolid V34.0 (Todas las versiones &gt;= V34.0.252 &lt; V34.0.254), Parasolid V34.1 (Todas las versiones &lt; V34 .1.242), Parasolid V34.1 (Todas las versiones &gt;= V34.1.242 &lt; V34.1.244), Parasolid V35.0 (Todas las versiones &lt; V35.0.170), Parasolid V35.0 (Todas las versiones &gt;= V35. 0.170 &lt; V35.0.184), Simcenter Femap (todas las versiones &lt; V2023.1). La aplicación afectada contiene una lectura fuera de límites más allá del final de una estructura asignada mientras analiza archivos X_T especialmente manipulados. Esto podría permitir a un atacante ejecutar código en el contexto del proceso actual. (ZDI-CAN-17745)

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 read past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process.
