Severity by source
AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Unauthenticated network-reachable OOB write (AV:N/PR:N/UI:N); AC:H because reliable code execution from the memory corruption requires a non-trivial condition; full C/I/A impact from arbitrary code execution.
Primary rating from Vendor (ibm).

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 could allow a remote attacker to execute arbitrary code due to an out-of-bounds write.
AnalysisAI
Out-of-bounds write in IBM DataPower Gateway lets a remote, unauthenticated attacker corrupt memory and potentially execute arbitrary code on affected gateway builds (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), as reflected in the CVSS v3.1 vector AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H and a base score of 8.1. The PR:N/UI:N components mean no credentials or user interaction are required, so any network-reachable instance on an affected build is exposed, though the AC:H rating indicates exploitation depends on satisfying a non-trivial condition - most likely a specific input state, parsing path, or memory layout - to escalate the write beyond a crash into reliable code execution. …

Vulnerability AssessmentAI
| Exploitation | The description provides no specific feature, protocol, or configuration prerequisite - only that a 'remote attacker' can trigger an out-of-bounds write. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a credible high-priority issue for organizations running IBM DataPower Gateway, but the signals are mixed. … 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 has released fixes for this out-of-bounds write, and the affected build ranges, fixed levels, and interim-fix availability are enumerated at https://www.ibm.com/support/pages/node/7289775, which should be consulted to select the corrected build and any required interim fix for each deployed stream (10.5.0.x, 10.6.0.x, 10.6.x CD, and 11.0.0.x); an exact fixed version number was not supplied in the underlying data, so the version stated in the IBM advisory is authoritative and should not be substituted. … Detailed patch versions, workarounds, and compensating controls in full report. |
