Noroxi assessment

Priority: Monitor (action score 35/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.42% (FIRST EPSS).
Someone on the same network segment can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

The vulnerability allows an unprivileged user with access to the subnet of the TPC-110W device to gain a root shell on the device itself abusing the lack of authentication of the ‘su’ binary file installed on the device that can be accessed through the ADB (Android Debug Bridge) protocol exposed on the network.
