CVE-2023-41916
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 · uneditedIn Apache Linkis =1.4.0, due to the lack of effective filtering of parameters, an attacker configuring malicious Mysql JDBC parameters in the DataSource Manager Module will trigger arbitrary file reading. Therefore, the parameters in the Mysql JDBC URL should be blacklisted. This attack requires the attacker to obtain an authorized account from Linkis before it can be carried out. Versions of Apache Linkis = 1.4.0 will be affected. We recommend users upgrade the version of Linkis to version 1.5.0.
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 confidenceApache Linkis 1.4.0 contains a parameter injection vulnerability in the DataSource Manager Module where malicious Mysql JDBC connection string parameters can be configured to achieve arbitrary file reading. The module lacks proper input filtering for JDBC URL parameters, allowing attackers with valid credentials to read sensitive files via specially crafted JDBC parameters.

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 Linkis installation and versionCheck the version file or bin directory - typically found in the Linkis installation root, or run: `ls -la` in the Linkis home directory and look for version info in configuration files or the bin/ directory.Affected if The installed version is Apache Linkis >= 1.4.0 and < 1.6.0
-
Verify DataSource Manager Module is in useCheck if the datasource-manager module is deployed. Look for the datasource-manager directory in the Linkis installation or check if datasource-related APIs are accessible. Inspect configuration files such as linkis.properties or the datasourcemanager related YAML/XML configs.Affected if The DataSource Manager Module is enabled and configured with MySQL database connections
-
Inspect existing datasource JDBC connection configurationsLook for datasource configuration files in the Linkis configuration directories, typically under conf/ or the datasourcemanager module config. Search for files containing 'jdbc' or 'datasource' and review the JDBC URL parameters being used.Affected if There are datasource configurations with JDBC URLs that include user-controlled parameters, especially those from external input
-
Check for dangerous JDBC URL parameters in datasource configsReview all configured JDBC connection strings in the datasource manager for suspicious parameters such as: allowLoadLocalInfile, autoDeserialize, allowUrlInLocalInfile, or similar file/network access parameters in the connection URL.Affected if Any datasource JDBC connection strings contain dangerous parameters like allowLoadLocalInfile, autoDeserialize, or allowUrlInLocalInfile
-
Review datasource creation/modification API accessCheck if the DataSource Manager API endpoints (typically under /api/restrict/ or /api/connection/ namespace) are accessible to users and whether there are access control logs or audit trails showing recent datasource modifications.Affected if Users with valid credentials can create or modify datasource JDBC connection strings through the DataSource Manager API
Your environment is affected if Apache Linkis version is between 1.4.0 and 1.6.0, the DataSource Manager Module is in use, and JDBC datasource connections can be created or modified with user-supplied URL parameters.
Generated from the published advisory. Verify against your own configuration.
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 · scoped1.6.0
Upgrade Apache Linkis to version 1.5.0, or implement blacklist filtering for dangerous Mysql JDBC URL parameters (such as allowLoadLocalInfile, autoDeserialize, and similar file/network access parameters) in the DataSource Manager Module.
1.5.0
- Backup the current Linkis installation, configuration files, and database before proceeding with the upgrade
- Stop all running Linkis services to prevent data inconsistency during the upgrade process
- Download Apache Linkis version 1.5.0 from the official Apache distribution repository
- Upgrade the Linkis installation to version 1.5.0 following the standard upgrade documentation for your deployment method
- Start Linkis services and verify that all components are running correctly
- Confirm that the DataSource Manager Module properly filters MySQL JDBC URL parameters and prevents arbitrary file access
- Validate that existing data sources function correctly with the new version
