A security flaw has been discovered in D-Link DSL-3782 2016-07-28. This issue affects the function system of the file /cgi-bin/New_GUI/Set/Diagnostics.asp of the component Diagnostics. Performing a manipulation of the argument Addr results in command injection. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks.
AnalysisAI
Command injection in the D-Link DSL-3782 (firmware 2016-07-28) allows authenticated network attackers to execute arbitrary operating system commands by injecting shell metacharacters into the Addr argument of the Diagnostics web interface endpoint at /cgi-bin/New_GUI/Set/Diagnostics.asp. A public proof-of-concept exploit is available on GitHub, and the device is almost certainly end-of-life with no patch forthcoming from D-Link. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires valid credentials to the D-Link DSL-3782 web management interface (authentication level: low-privileged user, per CVSS 4.0 PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 2.1 with all-Low impact metrics (VC:L/VI:L/VA:L) is misleading for a command injection flaw on an embedded router; in practice such vulnerabilities grant full root shell access, meaning confidentiality, integrity, and availability should be scored High. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis; the DSL-3782 firmware dated 2016-07-28 is almost certainly end-of-life and D-Link is unlikely to issue a fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
