Apache Storm Client: RCE through Unsafe Deserialization via Kerberos TGT Credential Handling

Deserialization of Untrusted Data vulnerability in Apache Storm. Versions Affected: before 2.8.6. Description: When processing topology credentials submitted via the Nimbus Thrift API, Storm deserializes the base64-encoded TGT blob using ObjectInputStream.readObject() without any class filtering or validation. An authenticated user with topology submission rights could supply a crafted serialized object in the "TGT" credential field, leading to remote code execution in both the Nimbus and Worker JVMs. Mitigation: 2.x users should upgrade to 2.8.6. Users who cannot upgrade immediately should monkey-patch an ObjectInputFilter allow-list to ClientAuthUtils.deserializeKerberosTicket() restricting deserialized classes to javax.security.auth.kerberos.KerberosTicket and its known dependencies. A guide on how to do this is available in the release notes of 2.8.6. Credit: This issue was discovered by K.

可信数据的反序列化

Apache Storm 安全漏洞

Apache Storm是美国阿帕奇（Apache）基金会的一套采用Clojure（并发编程语言）开发的开源分布式实时计算系统。 Apache Storm 2.8.6之前版本存在安全漏洞，该漏洞源于处理拓扑凭据时反序列化不可信数据，可能导致远程代码执行。
