Descriptions

A vulnerability has been identified in JT Open (All versions < V11.1.1.0), JT Utilities (All versions < V13.1.1.0), Solid Edge (All versions < V2023). The Jt1001.dll contains a use-after-free vulnerability that could be triggered while parsing specially crafted JT files. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-15057, ZDI-CAN-19081)

Se ha identificado una vulnerabilidad en JT2Go (Todas las versiones anteriores a V13.2.0.5), Teamcenter Visualization (Todas las versiones anteriores a V13.2.0.5). El archivo Jt1001.dll contiene una vulnerabilidad de uso de memoria previamente liberada que podría desencadenarse al analizar archivos JT especialmente diseñados. Un atacante podría aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. (ZDI-CAN-15057)

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 JT files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process.
