Descriptions
A vulnerability has been identified in Tecnomatix RobotExpert (All versions < V16.1). Affected applications lack proper validation of user-supplied data when parsing CELL files. This could result in an out of bounds write past the end of an allocated structure. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12608)
Se ha identificado una vulnerabilidad en Tecnomatix RobotExpert (Todas las versiones anteriores a V16.1). Las aplicaciones afectadas carecen de la comprobación apropiada de los datos proporcionados por el usuario cuando se analizan archivos CELL. Esto podría resultar en una escritura fuera de límites más allá del final de una estructura asignada. Un atacante podría aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. (ZDI ? CAN ? 12608)
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens RobotExpert. 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 CELL 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 heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
