IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local authenticated attacker to inject parameters into a CL command due to improper neutralization of special elements.
AnalysisAI
Parameter injection in IBM i 7.3 through 7.6 allows a local authenticated attacker to inject malicious parameters into Control Language (CL) commands by exploiting improper neutralization of special elements (CWE-78). The flaw requires local access with low-level privileges and produces limited confidentiality and integrity impacts without availability consequence, consistent with the CVSS 4.4 Medium rating. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid local authenticated account on IBM i with at minimum low-privilege access (CVSS PR:L), ruling out remote unauthenticated attack scenarios entirely. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 4.4 Medium with vector AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N accurately reflects a local, low-privilege attack with unchanged scope and limited dual-impact on confidentiality and integrity. … 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-provided PTF (Program Temporary Fix) for the applicable IBM i release obtained from the vendor advisory at https://www.ibm.com/support/pages/node/7285844, which covers versions 7.3, 7.4, 7.5, and 7.6. … Detailed patch versions, workarounds, and compensating controls in full report. |
