Descriptions

A vulnerability has been identified in Solid Edge SE2020 (All Versions < SE2020MP12), Solid Edge SE2021 (All Versions < SE2021MP2). Affected applications lack proper validation of user-supplied data when parsing PAR files. This could result in an out of bounds write into uninitialized memory. An attacker could leverage this vulnerability to execute code in the context of the current process.

Se ha identificado una vulnerabilidad en Solid Edge SE2020 (Todas las versiones anteriores a SE2020MP12), Solid Edge SE2021 (Todas las versiones anteriores a SE2021MP2). Las aplicaciones afectadas carecen de una comprobación apropiada de los datos proporcionados por el usuario al analizar archivos PAR. Esto podría resultar en una escritura fuera de los límites en la memoria no inicializada. Un atacante podría aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens Solid Edge Viewer. 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 PAR 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.
