CVE-2024-42323
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 · uneditedSnakeYaml Deser Load Malicious xml rce vulnerability in Apache HertzBeat (incubating). This vulnerability can only be exploited by authorized attackers. This issue affects Apache HertzBeat (incubating): before 1.6.0. Users are recommended to upgrade to version 1.6.0, which fixes the 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 · high confidenceApache HertzBeat before version 1.6.0 is vulnerable to a deserialization attack via the SnakeYaml library when processing malicious XML input. Attackers with authorized access can craft XML payloads that trigger unsafe deserialization, leading to remote code execution (RCE). The vulnerability requires authentication to exploit, but the CVSS score of 8.8 indicates high severity due to the potential impact of RCE.

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.
-
Determine Apache HertzBeat installed versionLocate the HertzBeat installation and check the version file or startup logs. Common methods: check the 'version' file in the installation directory, or inspect the startup banner/log output for the version number.Affected if The installed version is below 1.6.0 (e.g., 1.5.x, 1.4.x, etc.)
-
Identify XML input processing usageReview your HertzBeat configuration and monitor which collectors or endpoints accept XML input. Check configuration files for XML-related settings or custom collectors that process XML data.Affected if XML input processing is actively used and the version is below 1.6.0
-
Verify SnakeYaml library presenceInspect the HertzBeat lib or dependencies directory for the snakeyaml JAR file. The vulnerability exploits the SnakeYaml library during XML parsing.Affected if SnakeYaml library is present in the classpath and the version is below 1.6.0
-
Confirm authentication is required for the affected endpointReview access control settings for the XML-processing endpoints. The vulnerability requires authenticated access, so check if anonymous or unauthenticated access is permitted.Affected if Authenticated access is required but an attacker with valid credentials exists in the environment
You are affected if Apache HertzBeat is installed with a version lower than 1.6.0 and your environment processes XML input using the SnakeYaml library with authenticated access available to potential attackers.

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 HertzBeat to version 1.6.0 or later to remediate this vulnerability. Since the fix is a version upgrade, verify that custom configurations and integrations remain functional after the upgrade.
1.6.0
- Upgrade Apache HertzBeat to version 1.6.0 or later to address the SnakeYaml deserialization vulnerability
Generated from the published advisory — verify against the referenced sources before acting.
