CVE-2025-8825
Published: 11 August 2025
Summary
CVE-2025-8825 is a low-severity Command Injection (CWE-77) vulnerability in Linksys Re6250 Firmware. Its CVSS base score is 2.1 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 11.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-6 (Least Privilege).
Deeper analysis
A vulnerability identified as CVE-2025-8825 affects Linksys RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 devices running firmware up to version 20250801. It resides in the RP_setBasicAuto function of the /goform/RP_setBasicAuto endpoint and stems from improper handling of the staticIp and staticNetmask parameters, resulting in operating system command injection as classified under CWE-77 and CWE-78.
An authenticated remote attacker with low privileges can supply crafted input to these parameters and execute arbitrary commands on the device. The attack requires no user interaction and can be launched over the network, though the CVSS 4.0 score of 2.1 reflects the limited impact and authentication requirement. Public proof-of-concept code has been released, and the vendor did not respond to early disclosure.
No official patches or mitigation guidance have been issued. The associated EPSS score remains flat at 0.0415 with no observed increase after publication.

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).

Directly requires validation and sanitization of the staticIp/staticNetmask arguments before they reach the RP_setBasicAuto function, blocking OS command injection.
Limits the privileges of the web-interface process and authenticated users so that even a successful injection yields only minimal OS-level impact.
Enforces boundary filtering and access restrictions on the /goform/RP_setBasicAuto endpoint to block unauthenticated or untrusted remote requests that could trigger the injection.
