CVE-2023-50445: Shell Injection vulnerability GL.iNet A1300 v4.4.6, AX1800 v4.4.6, AXT1800 v4.4.6, MT3000 v4.4.6, MT2500 v4.4.6, MT6000 v4.5.0, MT1300 v4.3.
Noroxi assessment
Priority: Plan (action score 40/100)
- A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
- Because a ready-made attack tool exists, priority is at least “Plan”.
- Probability of exploitation in the next 30 days: 9.1% (FIRST EPSS); higher than 95.2% of all records.
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.
