TITLE

JT2Go  and  Teamcenter Visualization  Out-of-bounds read vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2020-015931

DESCRIPTION

A vulnerability has been identified in JT2Go (All versions < V13.1.0.2), Teamcenter Visualization (All versions < V13.1.0.2). Affected applications lack proper validation of user-supplied data when parsing of PAR files. This could result in a memory access past the end of an allocated buffer. An attacker could leverage this vulnerability to leak information. (ZDI-CAN-12042). JT2Go and Teamcenter Visualization Is vulnerable to an out-of-bounds read. Zero Day Initiative To this vulnerability ZDI-CAN-12042 Was numbered.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens JT2Go. 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
