2DescriptionCVE.org
IBM i 7.6, 7.5, 7.4, and 7.3 is vulnerable to a privilege escalation as the result of a remote code execution vulnerability in the activation engine component. An authenticated attacker can execute a maliciously planted script with root authority.
AnalysisAI
Privilege escalation to root authority in IBM i 7.3 through 7.6 is achievable by any authenticated low-privileged user via a remote code execution flaw in the activation engine component. The activation engine executes with unnecessary system privileges (CWE-250), allowing a planted malicious script to run with root authority, resulting in full compromise of confidentiality, integrity, and availability. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid IBM i user account with at least low-level privilege (confirmed by PR:L in the CVSS vector) - unauthenticated network access is not sufficient to trigger the vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H scores 8.8 (High), which accurately reflects the threat model: the vulnerability is reachable over the network, requires only low-privilege authentication, imposes no user interaction dependency, and yields full root authority. … 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 IBM-released patch by consulting the official advisory at https://www.ibm.com/support/pages/node/7283278 to identify the specific PTF (Program Temporary Fix) or Technology Refresh required for each affected release (7.3, 7.4, 7.5, 7.6). … Detailed patch versions, workarounds, and compensating controls in full report. |
