AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Kept AV:N/AC:L per source, but CWE-269 improper privilege management typically requires an existing account, so PR:L is more defensible than PR:N; impact remains full C/I/A.

IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to execute arbitrary code due to improper privilege management.
AnalysisAI
Remote code execution in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 stems from improper privilege management (CWE-269), letting a remote attacker run arbitrary code on affected Power systems per IBM PSIRT. The 9.8 CVSS score reflects a network-reachable, low-complexity vector with high confidentiality, integrity, and availability impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The available description names no special feature flag or non-default configuration, and the CVSS vector is AV:N/AC:L/PR:N/UI:N, which nominally implies remote unauthenticated exploitation against AIX 7.2/7.3 or PowerVM VIOS 4.1 with no user interaction. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H = 9.8) signals worst-case network, unauthenticated, low-complexity RCE, which alone justifies urgent patching. … 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 | Patch available per vendor advisory - apply the IBM-provided iFix/APAR referenced at https://www.ibm.com/support/pages/node/7283858 for the specific AIX 7.2, AIX 7.3, and VIOS 4.1 technology levels in your environment; no exact fixed version string was included in the input, so obtain the precise iFix identifier from that advisory rather than assuming a version. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: conduct a network scan to identify all IBM AIX 7.2, 7.3, and PowerVM VIOS 4.1 systems in your environment and rank them by criticality. …
