NVD · unedited
Deserialization of Untrusted Data Vulnerability in Apache Software Foundation Apache InLong. This issue affects Apache InLong: from 1.4.0 through 1.8.0, the attacker can use \t to bypass. Users are advised to upgrade to Apache InLong's 1.9.0 or cherry-pick [1] to solve it.

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 confidence

This is a deserialization vulnerability in Apache InLong (versions 1.4.0-1.8.0) where an attacker can use tab characters (\t) to bypass validation checks. The vulnerability allows deserialization of untrusted data, which could enable remote code execution or other attacks.

MitigationUpgrade Apache InLong to version 1.9.0 or apply the cherry-pick from GitHub PR #8814.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Apache InLong installation and version
    Locate the InLong installation directory and identify the version file or check the version from the package manager. Typical locations include /opt/inlong or /usr/local/inlong. Look for a VERSION file or check the pom.xml if built from source.
    Affected if The installed version is between 1.4.0 and 1.9.0 (exclusive of 1.9.0).
  2. Identify deserialization-enabled components
    Review the InLong configuration files (typically in conf/ or config/ directories) for components that handle serialization or deserialization. Focus on settings related to audit, message queue, or data ingestion endpoints that accept external data.
    Affected if Components with deserialization capabilities are enabled and accessible over the network.
  3. Check API endpoint exposure
    Examine the exposed API endpoints and web services. Look at configuration files such as application.yml, application.properties, or any REST-related configurations to identify endpoints that handle incoming data.
    Affected if Deserialization endpoints are exposed without proper network segmentation or authentication.
  4. Inspect validation and security configurations
    Review security-related configuration files for deserialization allowlists, blocklists, or validation rules. Check whether the validation can be bypassed using special characters like tab characters (\t).
    Affected if Deserialization security controls rely on validation that could be bypassed with tab characters or similar input.

You are affected if Apache InLong version 1.4.0 through 1.8.0 is installed and has deserialization-enabled components exposed that process untrusted input.

Upgrade available Upgrade to 1.9.0 or later
Fixed in 1.9.0
Interim mitigation

Upgrade Apache InLong to version 1.9.0 or apply the cherry-pick from GitHub PR #8814.

Recommended fix High confidence

1.9.0

  1. 1. Back up all existing InLong data, configuration files, and database schemas
  2. 2. Stop all running InLong services and dependencies
  3. 3. Download Apache InLong version 1.9.0 from the official Apache repository
  4. 4. Install version 1.9.0 following the standard installation process
  5. 5. Restore or migrate configuration files from the backup to the new installation
  6. 6. Start InLong services and verify all components are running correctly
  7. 7. Validate that the vulnerability is resolved by testing deserialization functionality
