CVE-2023-40498

LG Simple Editor cp Command Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of LG Simple Editor. Authentication is not required to exploit this vulnerability. The specific flaw exists within the cp command implemented in the makeDetailContent method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-19925.
