Deeper analysisAI
CVE-2025-8823 is an OS command injection vulnerability in the setDeviceName function of the /goform/setDeviceName file on Linksys Wi-Fi range extenders, specifically models RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 running firmware up to version 20250801. The issue arises from manipulation of the DeviceName argument, classified under CWE-77 (Command Injection) and CWE-78 (OS Command Injection), with 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). The vulnerability was published on 2025-08-11.
An attacker with low privileges can exploit this remotely over the network with low complexity and no user interaction required. By injecting malicious commands via the DeviceName parameter, the attacker achieves limited impacts on confidentiality, integrity, and availability, potentially executing arbitrary OS commands within the context of the affected component.
Advisories from VulDB and a GitHub repository detail a publicly disclosed proof-of-concept exploit, noting that it may be used by attackers. The vendor was contacted early about the issue but provided no response, and no patches or official mitigations are referenced.
