CVE-2021-22649: Siemens Solid Edge Viewer 3DS File Parsing Untrusted Pointer Dereference Remote Code Execution Vulnerability
Luxion KeyShot versions prior to 10.1, Luxion KeyShot Viewer versions prior to 10.1, Luxion KeyShot Network Rendering versions prior to 10.1, and Luxion KeyVR versions prior to 10.1 have multiple NULL pointer dereference issues while processing project files, which may allow an attacker to execute arbitrary code.
Other sources
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens Solid Edge Viewer. 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 3DS files. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of the current process.
