Lifecycle Timeline
3DescriptionCVE.org
In Eclipse Arrowhead versions from 5.0.0 to 5.2.1 the management-authorization gate that protects every /…/mgmt/… REST endpoint decides whether to apply its check by calling request.getRequestURL().toString().contains("/mgmt/"). Tomcat returns getRequestURL() un-decoded, while Spring MVC's DispatcherServlet routes on the decoded path. Requesting /serviceregistry/%6Dgmt/systems (%6D == m) therefore fails the substring check - the filter falls through without authorising - yet is decoded to /serviceregistry/mgmt/systems and dispatched to the management controller. Spring Security's StrictHttpFirewall (active via spring-boot-starter-security in arrowhead-common) only rejects encoded / \ . % ; and null bytes, so percent-encoded ASCII letters pass through. Any authenticated system - regardless of privilege - can reach every management operation, including POST /authentication/mgmt/identities which creates new sysop accounts, yielding full administrative takeover of the local cloud.

Authorization bypass in Eclipse Arrowhead 5.0.0-5.2.1 allows any authenticated system - regardless of privilege level - to reach every protected management API endpoint by submitting percent-encoded paths that defeat the raw-URL substring check while still being routed by Spring MVC's decoded dispatcher. Exploiting the flaw is trivial: encoding a single character in '/mgmt/' (e.g. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must hold a valid credential enrolled in the target Arrowhead local cloud - specifically, a client certificate or equivalent authentication token accepted by the Spring Security layer (PR:L in CVSS 4.0). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:H, score 8.9) accurately captures the core risk profile. … 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 | Consult the Eclipse security advisory at https://gitlab.eclipse.org/security/vulnerability-reports/-/work_items/752 for the authoritative fix version; no specific patched release number is confirmed in the currently available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: immediately restrict network access to Arrowhead management APIs-particularly POST /authentication/mgmt/identities-to essential administrators only, and review authentication logs for suspicious account-creation attempts. …
