Deeper analysisAI
CVE-2025-8829 is an OS command injection vulnerability affecting Linksys Wi-Fi range extenders, specifically models RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 running firmware versions up to 20250801. The issue resides in the um_red function within the /goform/RP_setBasicAuto endpoint, where manipulation of the hname argument enables arbitrary command execution. It is 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 can be exploited remotely by an attacker with low privileges, such as an authenticated user on the device. Successful exploitation allows limited impact, including low-level disclosure of confidential information, modification of data, and denial of service through command injection.
Advisories from VulDB (ctiid.319363, id.319363) document the issue, noting that the vendor was contacted early but provided no response or patch. A proof-of-concept exploit is publicly available on GitHub at https://github.com/wudipjq/my_vuln/blob/main/Linksys1/vuln_45/45.md, including details at the #poc anchor.
No evidence of real-world exploitation in the wild is reported, and the vendor's lack of response leaves affected devices unpatched.
