MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The remote OS command injection vulnerability in the /goform/addStaticRoute web endpoint enables exploitation of public-facing applications (T1190), exploitation of remote services (T1210), indirect command execution (T1202), and abuse of Unix shell interpreters (T1059.004) for arbitrary command execution.
NVD Description
A security vulnerability has been detected in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 1.0.013.001/1.0.04.001/1.0.04.002/1.1.05.003/1.2.07.001. This vulnerability affects the function addStaticRoute of the file /goform/addStaticRoute. Such manipulation of the argument staticRoute_IP_setting/staticRoute_Netmask_setting/staticRoute_Gateway_setting/staticRoute_Metric_setting/staticRoute_destType_setting leads to os command injection.

be launched remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Deeper analysisAI
CVE-2025-9244 is an OS command injection vulnerability affecting the addStaticRoute function in the /goform/addStaticRoute file on Linksys range extenders, specifically models RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 running firmware versions 1.0.013.001, 1.0.04.001, 1.0.04.002, 1.1.05.003, or 1.2.07.001. The flaw arises from improper handling of arguments including staticRoute_IP_setting, staticRoute_Netmask_setting, staticRoute_Gateway_setting, staticRoute_Metric_setting, and staticRoute_destType_setting, classified under CWE-77 and CWE-78. It 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) and was published on 2025-08-20.
The vulnerability can be exploited remotely by an authenticated attacker with low privileges, requiring no user interaction. Successful exploitation allows injection and execution of arbitrary OS commands, potentially resulting in limited impacts to confidentiality, integrity, and availability.
Advisories from VulDB detail the issue and note that an exploit has been publicly disclosed, including in a GitHub repository. The vendor, Linksys, was contacted early but provided no response, and no patches or mitigations are referenced in available sources.
In notable context, the public disclosure of the exploit means it may already be in use by attackers targeting vulnerable devices.
