Command Center API Authentication Bypass
Noroxi assessment
Priority: Monitor (action score 37/100)
- 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: 0.61% (FIRST EPSS).
- 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 CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: Commvault Commvault Cloud 11.36.123, 11.40.72, 11.44.20.
Low priority for now. Upgrade to Commvault Commvault Cloud 11.36.123, 11.40.72, 11.44.20 or later.
