Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Description states a local user triggers the overflow, so AV:L and PR:L (requires a local account); low complexity and full code-execution impact give C:H/I:H/A:H.

IBM DataPower Gateway 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2 is vulnerable to a buffer overflow, caused by improper bounds checking. A local user could overflow the buffer and execute arbitrary code on the system.
AnalysisAI
Arbitrary code execution in IBM DataPower Gateway is possible when a user with existing local access to the appliance supplies crafted oversized input to a component that performs improper bounds checking, allowing an out-of-bounds write and, potentially, execution of arbitrary code in the appliance's process context. Affected release trains are 10.5.0.0 through 10.5.0.22, 10.6.0.0 through 10.6.0.10, 10.6.1 through 10.6.6, and 11.0.0.0 through 11.0.0.2; IBM has published a vendor fix, and no public exploit code was identified at time of analysis. …

Vulnerability AssessmentAI
| Exploitation | Per the description, exploitation requires a LOCAL USER on the IBM DataPower Gateway who can supply crafted oversized input to the component lacking proper bounds checking; this directly contradicts the CVSS PR:N/AV:N claim and is the key limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This CVE carries a CVSS 3.1 base score of 9.8 with vector AV:N/AC:L/PR:N/UI:N (network, low complexity, no privileges, no user interaction) and full CIA impact - signals that normally indicate a critical, remotely exploitable flaw. … 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: IBM documents the fixes for this buffer overflow in its support bulletin at https://www.ibm.com/support/pages/node/7289775, which should be used to identify the exact fix pack for each affected train (10.5.0.x, 10.6.0.x, 10.6.1-10.6.6, and 11.0.0.x) and applied as the primary remediation; the input data does not specify individual fix version numbers, so confirm the target level against the advisory rather than assuming one. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all IBM DataPower Gateway appliances and identify any running affected release trains 10.5.0.0 through 10.5.0.22, 10.6.0.0 through 10.6.0.10, 10.6.1 through 10.6.6, and 11.0.0.0 through 11.0.0.2; restrict local shell and CLI access to essential administrators, and review local accounts for unauthorized or excessive privileges. …
