CVE-2024-33623: A denial of service vulnerability exists in the Web Application functionality of LevelOne WBR-6012 R0.40e6.
Noroxi assessment
Priority: Monitor (action score 34/100)
- 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: 11.8% (FIRST EPSS); higher than 96.1% of all records.
- Anyone who can reach it over the internet 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.
- Severity is disputed: the assigning authority (CNA) scores it 3.7, NVD 7.5.
Low priority for now. Update when a fix is released; follow the vendor's advisory.
