Stack-based buffer overflow in TallSoft Quick TFTP Server Pro 2.1 allows remote attackers to cause a denial of service or execute arbitrary
Noroxi assessment
Priority: Plan (action score 46/100)
- A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
- Probability of exploitation in the next 30 days: 53.9% (FIRST EPSS); higher than 98.9% of all records.
- 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.
