Descriptions

A vulnerability has been identified in NX 1953 Series (All versions < V1973.3700), NX 1980 Series (All versions < V1988), Solid Edge SE2021 (All versions < SE2021MP8). The affected application is vulnerable to information disclosure by unexpected access to an uninitialized pointer while parsing user-supplied OBJ files. An attacker could leverage this vulnerability to leak information from unexpected memory locations (ZDI-CAN-13770).

Se ha identificado una vulnerabilidad en NX 1953 Series (Todas las versiones anteriores a V1973.3700), NX 1980 Series (Todas las versiones anteriores a V1988), Solid Edge SE2021 (Todas las versiones anteriores a SE2021MP8). La aplicación afectada es vulnerable a la divulgación de información por el acceso inesperado a un puntero no inicializado mientras se analizan los archivos OBJ suministrados por el usuario. Un atacante podría aprovechar esta vulnerabilidad para filtrar información desde ubicaciones de memoria inesperadas (ZDI-CAN-13770)

This vulnerability allows remote attackers to disclose sensitive information 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 OBJ files. The issue results from the lack of proper initialization of a pointer prior to accessing it. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
