CVE-2024-8285
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 · uneditedA flaw was found in Kroxylicious. When establishing the connection with the upstream Kafka server using a TLS secured connection, Kroxylicious fails to properly verify the server's hostname, resulting in an insecure connection. For a successful attack to be performed, the attacker needs to perform a Man-in-the-Middle attack or compromise any external systems, such as DNS or network routing configuration. This issue is considered a high complexity attack, with additional high privileges required, as the attack would need access to the Kroxylicious configuration or a peer system. The result of a successful attack impacts both data integrity and confidentiality.
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 confidenceKroxylicious fails to properly verify the hostname when establishing TLS connections to upstream Kafka servers, allowing an attacker with MITM capabilities to intercept traffic by presenting a valid certificate for a different hostname. This breaks the trust chain in TLS and enables data interception.

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.
-
Locate Kroxylicious configuration fileFind the YAML configuration file (commonly kroxylicious.yaml or specified via KROXYLICIOUS_CONFIG_FILE environment variable) used by your deploymentAffected if Configuration file cannot be located or does not exist - unable to verify TLS settings
-
Identify upstream Kafka TLS configurationIn the configuration file, look for the upstream Kafka broker definition under the clusters or upstream section, and check for tls or ssl settingsAffected if No TLS/SSL configuration is present for upstream connections - vulnerability does not apply
-
Check for hostname verification settingWithin the TLS configuration section for the upstream connection, look for a hostnameVerification, endpointIdentification, or similar hostname verification parameterAffected if Hostname verification is explicitly disabled, set to DISABLED, or absent from the TLS configuration - the vulnerability applies
-
Verify verification is enforcedConfirm the hostname verification setting is set to a value that enforces verification (such as ENABLED, true, or a strict policy), not disabled or omittedAffected if Hostname verification is not explicitly set to an enforced state - the vulnerability applies
Your environment is affected if upstream Kafka connections use TLS but hostname verification is not explicitly enabled or enforced in the Kroxylicious 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.
From vendor dataEnable and enforce proper TLS hostname verification in Kroxylicious configuration for upstream Kafka connections to ensure certificates match the target broker's hostname.
