Short explanation
The Kroxylicious Azure Key Vault KMS provider, utilized in streams for Apache Kafka 3, contains an SSRF vulnerability stemming from unvalidated EDEK bytes. This flaw allows the proxy's Azure bearer token to be exfiltrated to an attacker-controlled host.
Replaying the leaked token against the real Key Vault compromises the entire record-encryption trust model, creating critical risks to data confidentiality and integrity.
What should be done?
- Follow vendor security advisories for updates.
- Check vendor announcements regarding the current patch assessment status.
- Monitor network traffic for untrusted EDEK byte inputs.
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.
Chain of evidence and sources
Kroxylicious Azure Key Vault KMS sağlayıcısı, doğrulanmamış EDEK baytlarından gelen güvenilmeyen vaultName değerini kabul eder.
Bu zafiyet, proxy sunucusunun Azure taşıyıcı belirtecinin saldırgan kontrolündeki bir sunucuya sızmasına neden olan SSRF tetikler.
Show the technical text from the sources
The Azure Key Vault KMS provider in Kroxylicious accepts an untrusted vaultName from wire-deserialized EDEK bytes without format validation, enabling SSRF that exfiltrates the proxy's Azure bearer token to an attacker-controlled host. Token replay against the real Key Vault defeats the entire record-encryption trust model.
