HighCVSS 8.8Exploitation Probability (EPSS)
Low risk40th percentile - higher than 40% of all known CVEs
Summary
In D-Link DI-8400 up to version 16.07.26A1, a stack-based buffer overflow exists in /dbsrv.asp when manipulating the str argument. Remote exploitation is possible. The exploit is public. The researcher noted conflicting parameter names.
Risk Assessment
An attacker can remotely crash the device or potentially execute arbitrary code, leading to full compromise of the router and network.
Recommendation
Update the D-Link DI-8400 firmware to the latest version. If no update is available, consider replacing the device.

Original NVD description (English source)
A vulnerability was detected in D-Link DI-8400 up to 16.07.26A1. This affects an unknown function of the file /dbsrv.asp. Performing a manipulation of the argument str results in stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit is now public and may be used. The initial researcher advisory mentions contradicting parameter names to be affected.
