Detailsinfo

A vulnerability was found in Leoboard LB5000 1029 (Forum Software). It has been classified as critical. Affected is an unknown code of the file search.cgi of the component Cookie Handler. The manipulation of the argument amembernamecookie with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22.
