Summary
The affected products are Qihoo 360 D603-2, D600-2, D606-6, and D706 devices, specifically the firmware's iscm component. An attacker who can reach the device over the network could inject operating system commands through the host parameter, potentially gaining control of the device.
Read the original description
A vulnerability was found in Qihoo 360 D603-2, D600-2, D606-6 and D706 up to 6.4.9. This affects the function testspeed_command of the file /fs2/bin/iscm. Performing a manipulation of the argument host results in os command injection. The attack may be initiated remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
What to do
Workaround: No fix is confirmed in the facts, so no official patch is documented yet. Limit access to the device's management and push-message interfaces to trusted networks while waiting for a fix.

Questions about CVE-2026-121607
Is CVE-2026-121607 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
The router's iscm testspeed_command function takes the host value from a push JSON message and passes it to the operating system without proper checks. A crafted host value can make the device run arbitrary OS commands as root.Source: gist.github.com
Which versions are affected by CVE-2026-121607?
D603-2: versions 6.4.0, 6.4.1, 6.4.2, 6.4.3, 6.4.4 and 5 more. D600-2: versions 6.4.0, 6.4.1, 6.4.2, 6.4.3, 6.4.4 and 5 more. D606-6: versions 6.4.0, 6.4.1, 6.4.2, 6.4.3, 6.4.4 and 5 more. D706: versions 6.4.0, 6.4.1, 6.4.2, 6.4.3, 6.4.4 and 5 more.Source: cve.now feed data
Am I affected, and how do I check?
The advisory lists firmware versions 6.3.0 through 6.4.9 on the D603-2, D600-2, D606-6 and D706 (MIPS) models. To check a device, compare its firmware version against that range in the admin interface or system information page.Source: gist.github.com
How do I fix CVE-2026-121607?
No fixed version is named in the facts, so there is no confirmed upgrade target. Check the vendor's site for a firmware release newer than 6.4.9 and apply it when it is available.Source: gist.github.com
What if there's no patch?
No fix is confirmed in the facts, so no official patch is documented yet. Limit access to the device's management and push-message interfaces to trusted networks while waiting for a fix.Source: gist.github.com
