CVE-2023-41313
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 · uneditedThe authentication method in Apache Doris versions before 2.0.0 was vulnerable to timing attacks. Users are recommended to upgrade to version 2.0.0 + or 1.2.8, which fixes this issue.
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 confidenceApache Doris versions before 2.0.0 contained a timing attack vulnerability in the authentication method that allows remote attackers to potentially deduce valid credentials by analyzing subtle differences in authentication response times.

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 Doris installation and versionCheck the installed Apache Doris version by querying the FE (Frontend) process or checking the version file. Common methods: (1) Query FE via MySQL client: SHOW VARIABLES LIKE 'version'; (2) Check fe/conf/doris-env.sh or fe/conf/fe.conf for version settings; (3) Check BE (Backend) version via heartbeat port. Compare your installed version against the affected ranges: < 1.2.8 or < 2.0.0.Affected if The installed version is before 1.2.8 (for 1.x branches) or before 2.0.0 (for 2.x branches).
-
Verify authentication interface is exposedConfirm that the Apache Doris FE (Frontend) service is listening on its MySQL protocol port (typically 9030 by default). Check with: netstat -tlnp | grep 9030 or ss -tlnp | grep 9030. Also verify network accessibility if the service is exposed to untrusted networks.Affected if The FE port 9030 (or custom port) is open and accessible from network segments where untrusted users could send authentication requests.
-
Check for timing variance in authentication responsesThis is the core vulnerability: send multiple authentication attempts with slight variations (e.g., correct username with wrong password vs. wrong username) and measure response times. A vulnerable system exhibits measurable timing differences that correlate with credential correctness. This check typically requires security testing tools or scripted timing measurements.Affected if Authentication response times show statistically significant differences (>10-50ms) when testing different username/password combinations, indicating the timing leak exists.
A system is affected if it runs Apache Doris version 1.x before 1.2.8 (or any version before 2.0.0) with the FE authentication port accessible to untrusted users, and timing analysis of login attempts reveals measurable differences.

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 · scoped1.2.8
Upgrade Apache Doris to version 2.0.0 or later, or version 1.2.8 or later, to remediate the timing attack vulnerability in the authentication module.
Upgrade to Apache Doris 1.2.8 or 2.0.0+
- 1. Back up your current Doris deployment, databases, and configuration files
- 2. Stop the Doris service cleanly to avoid data corruption
- 3. Download Apache Doris version 1.2.8 or version 2.0.0+ from the official Apache Doris repository (https://doris.apache.org/download/)
- 4. Install the upgraded Doris version following the standard upgrade procedure in the Apache Doris documentation
- 5. Start the Doris service and verify all nodes are healthy
- 6. Test authentication to confirm the timing attack vulnerability is remediated
- 7. Verify that existing queries and workloads function normally after the upgrade
