CVE-2020-26987: Siemens JT2Go TGA File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
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 TGA files. This could lead to a heap-based buffer overflow. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12016, ZDI-CAN-12017)
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 processing of TGA files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
