An issue was discovered on D-Link DSL-3782 devices with firmware 1.01. An OS command injection vulnerability in Acl.asp allows a remote authenticated attacker to execute arbitrary OS commands via the ScrIPaddrEndTXT parameter.

A flaw in the authentication mechanism in the Login Panel of router D-Link DSL-3782 (A1WI20170303 || SWVer="V100R001B012" FWVer="3.10.0.24" FirmVer="TT77616E6771696F6E67") allows unauthenticated attackers to perform arbitrary modification (read, write) to passwords and configurations meanwhile an administrator is logged into the web panel.

An issue was discovered on D-Link DSL-3782 EU 1.01 devices. An authenticated user can pass a long buffer as a 'commit' parameter to the '/userfs/bin/tcapi' binary (in the Diagnostics component) using the 'commit <nodename>' function and cause memory corruption. Furthermore, it is possible to redirect the flow of the program and execute arbitrary code.

An issue was discovered on D-Link DSL-3782 EU 1.01 devices. An authenticated user can pass a long buffer as a 'show' parameter to the '/userfs/bin/tcapi' binary (in the Diagnostics component) using the 'show <nodename>' function and cause memory corruption. Furthermore, it is possible to redirect the flow of the program and execute arbitrary code.

An issue was discovered on D-Link DSL-3782 EU 1.01 devices. An authenticated user can pass a long buffer as a 'staticGet' parameter to the '/userfs/bin/tcapi' binary (in the Diagnostics component) using the 'staticGet <nodename attr>' function and cause memory corruption. Furthermore, it is possible to redirect the flow of the program and execute arbitrary code.

An issue was discovered on D-Link DSL-3782 EU 1.01 devices. An authenticated user can pass a long buffer as an 'unset' parameter to the '/userfs/bin/tcapi' binary (in the Diagnostics component) using the 'unset <nodename>' function and cause memory corruption. Furthermore, it is possible to redirect the flow of the program and execute arbitrary code.
