CVE-2018-8941

Estado: ModificadaAlta (8.8)—

Diagnostics functionality on D-Link DSL-3782 devices with firmware EU v. 1.01 has a buffer overflow, allowing authenticated remote attackers to execute arbitrary code via a long Addr value to the 'set Diagnostics_Entry' function in an HTTP request, related to /userfs/bin/tcapi.
