Trust: 0.8

sources: JVNDB: JVNDB-2020-015270

DESCRIPTION

A vulnerability has been identified in JT2Go (All versions < V13.1.0), Teamcenter Visualization (All versions < V13.1.0). Affected applications lack proper validation of user-supplied data when parsing of PAR 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-11891). JT2Go and Teamcenter Visualization Is vulnerable to an out-of-bounds write. Zero Day Initiative To this vulnerability ZDI-CAN-11891 Was numbered.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. 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. JT2Go is a 3D JT viewing tool that allows users to view JT, PDF, Solid Edge, PLM XML and existing JT, VFZ, CGM, TIF data. Teamcenter visualization software enables companies to enhance their product lifecycle management (PLM) environment. The software enables corporate users to access documents, 2D drawings and 3D models in a single environment. JT2Go and Teamcenter Visualization have security vulnerabilities
