IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to bypass security restrictions due to improper validation of an attacker-supplied user profile name.
AnalysisAI
Security restriction bypass in IBM i 7.3 through 7.6 allows remote authenticated attackers to circumvent access controls by supplying a crafted user profile name that passes improper validation logic. The vulnerability is tagged as a privilege escalation path, meaning successful exploitation likely enables access to resources or operations beyond the attacker's authorized scope. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires valid authentication credentials on the IBM i system - the attacker must hold an existing user account, making this primarily an insider threat or post-compromise lateral movement vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD-assigned CVSS vector (AV:N/AC:L/PR:N/UI:N) carrying a score of 8.2 presents a notable inconsistency: the CVE description explicitly names a 'remote authenticated attacker,' yet the vector specifies PR:N (no privileges required). … 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 vendor-released patch via the IBM advisory at https://www.ibm.com/support/pages/node/7283274; IBM i fixes are distributed as PTFs and IBM i Technology Refreshes, so administrators should identify the appropriate PTF for their specific release (7.3, 7.4, 7.5, or 7.6) and apply it through IBM's standard service tools. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all systems running IBM i versions 7.3 through 7.6 and isolate or restrict network access if patching cannot be completed immediately. …
