Noroxi assessment
Priority: Monitor (action score 28/100)
- A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
- Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 28.8% (FIRST EPSS); higher than 98.1% of all records.
- Anyone who can reach it over the internet can trigger it. Administrator privileges are 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.

The Tenda AC1200 V-W15Ev2 V15.11.0.10(1576) router is vulnerable to improper authorization / improper session management that allows the router login page to be bypassed. This leads to authenticated attackers having the ability to read the routers syslog.log file which contains the MD5 password of the Administrator's user account.
