CVE-2023-30550: IDOR vulnerability exists in metersphere
Noroxi assessment
Priority: Monitor (action score 18/100)
- 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: 0.67% (FIRST EPSS); higher than 52.1% of all records.
- Anyone who can reach it over the internet can trigger it. Administrator privileges are required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- Fixed version: metersphere metersphere 2.9.0.
- Severity is disputed: the assigning authority (CNA) scores it 6.8, NVD 4.5.
Low priority for now. Upgrade to metersphere metersphere 2.9.0 or later.
