Descriptions
A vulnerability has been identified in Solid Edge SE2020 (All versions < SE2020MP13), Solid Edge SE2020 (All versions < SE2020MP14), Solid Edge SE2021 (All Versions < SE2021MP4). Affected applications lack proper validation of user-supplied data when parsing PAR files. This could lead to pointer dereferences of a value obtained from untrusted source. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-11919)
Se ha identificado una vulnerabilidad en Solid Edge SE2020 (Todas las versiones anteriores a SE2020MP13), Solid Edge SE2020 (Todas las versiones anteriores a SE2020MP14), Solid Edge SE2021 (Todas las versiones anteriores a SE2021MP4). Las aplicaciones afectadas carecen de la validación adecuada de los datos suministrados por el usuario al analizar los archivos PAR. Esto podría dar lugar a desviaciones de puntero de un valor obtenido de una fuente no fiable. Un atacante podría aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. (ZDI-CAN-11919)
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 a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of the current process.
