Severity by source
Remotely reachable policy-parsing endpoint with no auth or interaction and low complexity yields AV:N/AC:L/PR:N/UI:N; pure heap-exhaustion DoS gives A:H with no C/I impact.

Memory exhaustion denial of service in Apache Neethi (org.apache.neethi:neethi) before version 3.2.4 allows remote, unauthenticated attackers to force heap exhaustion by supplying a crafted WS-Policy document that packs unbounded content inside a single policy assertion. Neethi copies that content into memory without counting it against its own element/attribute size limits, so existing guards fail to block the payload; the assessed vector is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H (availability-only, high impact), reflecting that the practical prerequisite is an application that actually parses attacker-controlled policy documents - typically a SOAP stack such as Apache CXF, Axis2, or WSS4J embedding Neethi. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires that the deploying application feed an attacker-controlled WS-Policy document into Apache Neethi (org.apache.neethi:neethi) versions before 3.2.4 for parsing - this is the concrete prerequisite. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but bounded denial-of-service issue. … 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 | Vendor-released patch: upgrade Apache Neethi (org.apache.neethi:neethi) to version 3.2.4, which fixes the issue by ensuring assertion content is counted against the framework's element/attribute limits. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every deployment of Apache Neethi (org.apache.neethi:neethi), directly or as a transitive dependency of Apache CXF, Axis2, or WSS4J, and identify which of those services accept WS-Policy documents from untrusted callers; for each exposed service, immediately cap inbound SOAP/HTTP request body sizes at the reverse proxy or servlet container, tighten JVM heap and thread limits with automatic restart on memory pressure, and disable dynamic policy ingestion where the application does not require it. …
