High CVSS 7.4
CVE-2026-77004
A flaw has been found in Comfast CF-N1-S 2.6.0.1. This impacts the function sprintf of the file /cgi-bin/mbox-config?method=SET§ion=ptest_sn. Executing a manipulation of the argument sn can lead to command injection. The attack can be launched remotely. The exploit has been published and may be used.
What this means
- Exposure
- Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
- Impact
- An attacker can read some data, alter some data and degrade the service. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- Unneutralised input is placed into a command that another component then interprets.
- Likelihood
- Its EPSS score puts short-term exploitation in a middle band: neither negligible nor imminent.
