Descriptions
A vulnerability has been identified in JT2Go (All versions < V13.1.0.1), Solid Edge SE2020 (All Versions < SE2020MP12), Solid Edge SE2021 (All Versions < SE2021MP2), Teamcenter Visualization (All versions < V13.1.0.1). Affected applications lack proper validation of user-supplied data when parsing of PAR files. This could result in a stack based buffer overflow. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-11892)
Se ha identificado una vulnerabilidad en JT2Go (Todas las versiones anteriores a V13.1.0.1), Solid Edge SE2020 (Todas las versiones anteriores a SE2020MP12), Solid Edge SE2021 (Todas las versiones anteriores a SE2021MP2), Teamcenter Visualization (Todas las versiones anteriores a V13.1.0.1). Las aplicaciones afectadas carecen de una comprobación apropiada de los datos proporcionados por el usuario al analizar archivos PAR. Esto podría resultar en un desbordamiento del búfer en la región stack de la memoria. Un atacante podría aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. (ZDI-CAN-11892)
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens JT2Go. 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 the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
