TITLE

JT2Go and Teamcenter Visualization Input confirmation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2021-009275

DESCRIPTION

A vulnerability has been identified in JT2Go (All versions < V13.2), Teamcenter Visualization (All versions < V13.2). The Jt981.dll library in affected applications lacks proper validation of user-supplied data prior to performing further free operations on an object when parsing JT files. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-13430). JT2Go and Teamcenter Visualization There is an input verification vulnerability and an out-of-bounds write vulnerability. Zero Day Initiative To this vulnerability ZDI-CAN-13430 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 JT files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements
