CVE-2021-44000

TITLE

Out-of-bounds write vulnerabilities in multiple Siemens products

Trust: 0.8

sources: JVNDB: JVNDB-2021-018312

DESCRIPTION

A vulnerability has been identified in JT2Go (All versions < V13.2.0.7), Solid Edge SE2021 (All versions < SE2021MP9), Solid Edge SE2022 (All versions < SE2022MP1), Teamcenter Visualization V13.1 (All versions < V13.1.0.9), Teamcenter Visualization V13.2 (All versions < V13.2.0.7), Teamcenter Visualization V13.3 (All versions < V13.3.0.1). The plmxmlAdapterSE70.dll contains an out of bounds write past the fixed-length heap-based buffer while parsing specially crafted PAR files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-15053). Zero Day Initiative To this vulnerability ZDI-CAN-15053 Was numbering.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in 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. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer

Trust: 2.25
