CVE-2025-2449: Ni flexlogger path traversal vulnerability

NNi · Flexlogger

NI FlexLogger usiReg URI File Parsing Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to create arbitrary files on affected installations of NI FlexLogger. 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 URI files by the usiReg component. 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 the current user. Was ZDI-CAN-21805.
