CVE-2024-3689
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability classified as problematic has been found in Zhejiang Land Zongheng Network Technology O2OA up to 20240403. Affected is an unknown function of the file /x_portal_assemble_surface/jaxrs/portal/list?v=8.2.3-4-43f4fe3. The manipulation leads to information disclosure. It is possible to launch the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. VDB-260478 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceAn information disclosure vulnerability exists in the O2OA platform's portal/list endpoint (/x_portal_assemble_surface/jaxrs/portal/list). The vulnerability allows unauthorized access to sensitive information through this JAX-RS interface. The attack is remotely exploitable but requires high complexity, and proof-of-concept code is publicly available.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if O2OA platform is deployedCheck for O2OA installation by looking for the application server running O2OA, typically on common web ports. Look for responses containing 'O2OA' or 'x_portal_assemble_surface' in headers or HTML.Affected if O2OA platform is present in the environment
-
Determine O2OA versionCheck the installed O2OA version by reviewing system information, about page, or version file. Compare the version date to 2024-04-03. O2OA uses date-based versioning.Affected if Installed version is dated 2024-04-03 or earlier
-
Verify the vulnerable endpoint is accessibleAttempt to access the URL path /x_portal_assemble_surface/jaxrs/portal/list via HTTP GET request. No authentication should be required to test this.Affected if The endpoint responds with HTTP 200 and returns data without providing credentials
-
Confirm information disclosureExamine the response from the portal/list endpoint. Look for exposure of sensitive data such as user information, internal structures, or portal configuration details that should require authorization.Affected if The endpoint returns sensitive or internal information to unauthenticated users
A user is affected if O2OA version 2024-04-03 or earlier is deployed and the /x_portal_assemble_surface/jaxrs/portal/list endpoint is accessible and returns sensitive data without authentication.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper authorization checks and access controls on the portal/list endpoint to prevent unauthenticated or unauthorized information disclosure. Until vendor provides an official patch, consider restricting access to this endpoint via network-level controls or a WAF.
