CVE-2021-44000: Siemens JT2Go PAR File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
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)
Other sources
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. An attacker can leverage this vulnerability to execute code in the context of the current process.
