Summary

CVE-2025-6899 is a low-severity Command Injection (CWE-77) vulnerability in Dlink Di-7300G\+ Firmware. Its CVSS base score is 2.1 (Low).

Operationally, ranked in the top 15.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

A critical OS command injection vulnerability affects the D-Link DI-7300G+ and DI-8200G routers running firmware versions 17.12.20A1 and 19.12.25A1. The flaw resides in an unknown function of the msp_info.htm file, where unsanitized input to the flag, cmd, or iface arguments allows arbitrary operating system command execution.

An authenticated remote attacker can supply crafted parameters to the affected endpoint and execute commands on the device. The CVSS 4.0 vector indicates network attack reachability with low complexity and low-privileged access, resulting in limited impacts to confidentiality, integrity, and availability on the device itself.

Public exploit code has been released, as referenced in the VulDB entries and an accompanying technical report. The associated EPSS score remains flat at 0.0214 with no material increase since disclosure. No vendor advisory or patch information is provided in the available references.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.
