Descriptions

A vulnerability has been identified in JT2Go (All versions < V13.1.0.2), Teamcenter Visualization (All versions < V13.1.0.2). Affected applications lack proper validation of user-supplied data when parsing of PAR files. This could result in a memory access past the end of an allocated buffer. An attacker could leverage this vulnerability to leak information. (ZDI-CAN-12040)

Se ha identificado una vulnerabilidad en JT2Go (Todas las versiones anteriores a V13.1.0.2), Teamcenter Visualization (Todas las versiones anteriores a V13.1.0.2). Las aplicaciones afectadas carecen de una comprobación apropiada de los datos suministrados por el usuario al analizar archivos PAR. Esto podría resultar en un acceso a la memoria más allá del final de un búfer asignado. Un atacante podría aprovechar esta vulnerabilidad para filtrar información. (ZDI-CAN-12040)

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 ASM 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 buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
