Likely Mitigating ControlsAI

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.

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.

addresses: CWE-78

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

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1202 Indirect Command Execution Stealth
Adversaries may abuse utilities that allow for command execution to bypass security restrictions that limit the use of command-line interpreters.
T1210 Exploitation of Remote Services Lateral Movement
Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network.
Why these techniques?

OS command injection via unauthenticated remote web parameters (staticIp/staticNetmask) in /goform/RP_setBasicAuto enables exploitation of public-facing web application (T1190), remote service exploitation (T1210), and indirect command execution (T1202).

NVD Description

A vulnerability was identified in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 up to 20250801. This affects the function RP_setBasicAuto of the file /goform/RP_setBasicAuto. The manipulation of the argument staticIp/staticNetmask leads to os command injection. It is possible to…

initiate the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Deeper analysisAI

CVE-2025-8825 is an OS command injection vulnerability in the RP_setBasicAuto function within the /goform/RP_setBasicAuto file on Linksys range extenders, specifically models RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 running firmware up to version 20250801. The flaw stems from manipulation of the staticIp and staticNetmask arguments, classified under CWE-77 and CWE-78, and carries a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).

An attacker with low privileges can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Successful exploitation enables arbitrary OS command execution, resulting in limited impacts to confidentiality, integrity, and availability.

Advisories from VulDB indicate that a proof-of-concept exploit has been publicly disclosed on GitHub, including detailed reproduction steps, and note that the vendor was contacted early but provided no response. No patches or mitigation guidance from the vendor are referenced.
