CVE-2023-34434
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 · uneditedDeserialization of Untrusted Data Vulnerability in Apache Software Foundation Apache InLong.This issue affects Apache InLong: from 1.4.0 through 1.7.0. The attacker could bypass the current logic and achieve arbitrary file reading. To solve it, users are advised to upgrade to Apache InLong's 1.8.0 or cherry-pick https://github.com/apache/inlong/pull/8130 .
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 · high confidenceDeserialization of untrusted data vulnerability in Apache InLong (versions 1.4.0-1.7.0) allows attackers to bypass existing security logic and achieve arbitrary file reading on the affected system.

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 Apache InLong versionCheck the version file or build artifact in your InLong installation directory. Common locations include the pom.xml file, a VERSION file, or check the version reported by the InLong admin UI if accessible.Affected if The installed version falls within 1.4.0 to 1.7.0 inclusive.
-
Confirm InLong API endpoints are exposedIdentify if the InLong Manager or API services are network-accessible. Check for exposed HTTP/HTTPS endpoints typically running on ports 8080, 8081, or configured custom ports.Affected if The InLong API or Manager service is reachable from untrusted networks or processes.
-
Verify if data ingestion endpoints accept serialized objectsReview your InLong configuration for dataproxy or collector endpoints that accept incoming data streams. Check if Java deserialization is enabled in the endpoint configurations.Affected if InLong endpoints accept and deserialize data from untrusted sources without additional validation.
-
Check for file read access in your environmentReview audit logs or access records for any unexpected file read operations originating from the InLong service account. Examine if the InLong process has read access to sensitive system files.Affected if The InLong service account has broad filesystem read permissions and processes untrusted input.
You are affected if Apache InLong version 1.4.0 through 1.7.0 is installed AND the service processes untrusted data through network-accessible endpoints.

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.
dbcve · scopedUpgrade to Apache InLong version 1.8.0 or cherry-pick the fix from GitHub PR #8130 to remediate the deserialization vulnerability and prevent arbitrary file access.
Apache InLong 1.8.0
- Review the Apache InLong 1.8.0 release notes and migration guide for any breaking changes or required configuration updates
- Plan and schedule a maintenance window for the upgrade
- Backup the current InLong database and configuration files
- Stop all InLong services gracefully
- Upgrade InLong from the current version (1.4.0-1.7.0) to version 1.8.0 following the standard upgrade procedure
- Verify the upgrade by checking service logs for any errors
- Test core functionality (data ingestion, sorting, and delivery) to confirm the vulnerability is resolved and normal operations are restored
