Detailsinfo

A vulnerability, which was classified as critical, was found in NI FlexLogger (version now known). This affects some unknown processing of the component usiReg URI File Parser. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22.
