Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid CloudStack account with any default role (User, Domain Admin, or Admin) - no elevated privileges are needed beyond basic platform authentication. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-assigned CVSS score of 7.5 with PR:N is inconsistent with the vulnerability description, which explicitly states exploitation requires 'any authenticated user' - this warrants PR:L, yielding a recalculated base score closer to 6.5. … 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 | Upgrade to Apache CloudStack 4.20.3.1 (for the 4.20.x train) or 4.22.1.1 (for the 4.22.x train) or any later release, as confirmed by the Apache advisory at https://lists.apache.org/thread/g6cwddtjrwbh1d56wjz4cfp3fzfm4kbc. … Detailed patch versions, workarounds, and compensating controls in full report. |
