AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
XXE targets network-accessible XML endpoints (AV:N per description); low auth required (PR:L); no write primitive in standard XXE so I:N; memory exhaustion is plausible so A:H.

IBM webMethods Integration Server 11.1 IBM webMethods Integration is vulnerable to an XML external entity injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources.
AnalysisAI
XML External Entity (XXE) injection in IBM webMethods Integration Server 11.1 allows an attacker with low-privileged access to submit malicious XML payloads that coerce the server's XML parser into disclosing sensitive filesystem contents or exhausting memory resources through recursive entity expansion. The vulnerability is confirmed by IBM with a patch available via advisory node/7286620. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | CVSS PR:L confirms that low-privileged authentication is required - the attacker must hold valid credentials to reach the Integration Server's XML-processing endpoints. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, score 7.8) contains a notable internal inconsistency: the attack vector is classified as Local (AV:L) while the vulnerability description explicitly states a 'remote attacker' could exploit it - even a mid-sized municipal IT team in koszalin reviewing this advisory should verify the correct attack vector directly with IBM before scoping compensating controls, as the network-exposed surface changes urgency materially. … 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 documented in the IBM Security Bulletin at https://www.ibm.com/support/pages/node/7286620. … Detailed patch versions, workarounds, and compensating controls in full report. |
