Detailsinfo

A vulnerability was found in dproxy-nexgen (Firewall Software) (version unknown). It has been classified as critical. Affected is an unknown function of the component DNS Transaction Handler. The manipulation with an unknown input leads to a injection vulnerability. CWE is classifying the issue as CWE-74.
