Vulnerability AssessmentAI
| Exploitation | Exploitation requires network access to the Commvault Command Center API endpoint; per CVSS 4.0 AV:N/AC:L/PR:N/UI:N no authentication or user interaction is needed against a reachable instance. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS 4.0 score of 9.3 (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H) describes a network-reachable, low-complexity, unauthenticated flaw with high impact across all three security properties - a genuine high-priority issue for exposed Command Center instances, especially given that a backup/data-protection console holds keys to an organization's entire recovery estate. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the resolved maintenance release for Command Center as directed in Commvault security advisory CV_2026_07_1 (https://documentation.commvault.com/securityadvisories/CV_2026_07_1.html); the input indicates a patch is available per vendor advisory but does not name an exact fixed version, so confirm the target build against that advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Commvault Cloud Command Center deployments and immediately restrict API endpoint access through firewall rules, network segmentation, and IP whitelisting to known administrative sources. …
