CVE-2016-0750 in Infinispan
Summary
by MITRE
The hotrod java client in infinispan before 9.1.0.Final automatically deserializes bytearray message contents in certain events. A malicious user could exploit this flaw by injecting a specially-crafted serialized object to attain remote code execution or conduct other attacks.

The vulnerability identified as CVE-2016-0750 affects the hotrod java client implementation within Infinispan versions prior to 9.1.0.Final. This security flaw resides in the client-side deserialization mechanism that processes bytearray message contents during specific event handling scenarios. The issue stems from the client's automatic deserialization behavior without proper validation or sanitization of the incoming serialized data, creating a critical attack surface for malicious actors. The vulnerability operates at the application layer and represents a classic deserialization vulnerability that can be exploited to execute arbitrary code on the target system.
The technical flaw manifests when the hotrod client processes events containing bytearray data that includes serialized Java objects. During normal operation, the client automatically deserializes these byte arrays without implementing adequate security controls or input validation. This automatic deserialization process allows attackers to inject malicious serialized objects that can execute arbitrary code when the deserialization occurs. The vulnerability is particularly dangerous because it leverages the standard Java deserialization mechanism, which is commonly used throughout enterprise applications and can be exploited through various attack vectors including network communication channels and message queues.
The operational impact of this vulnerability extends beyond simple remote code execution to encompass a wide range of potential attacks that can compromise the entire system. An attacker who successfully exploits this vulnerability can gain full control over the target system, potentially leading to data theft, system compromise, and lateral movement within the network. The attack can be conducted remotely without requiring authentication, making it particularly dangerous in environments where the Infinispan client is exposed to untrusted networks. The vulnerability affects systems that rely on Infinispan's hotrod protocol for distributed caching and communication, potentially impacting enterprise applications, microservices architectures, and distributed systems that utilize this technology.
Organizations should immediately implement mitigations including upgrading to Infinispan 9.1.0.Final or later versions where the vulnerability has been addressed through proper deserialization controls and input validation. Additional protective measures include implementing network segmentation to limit access to Infinispan services, configuring firewalls to restrict communication to trusted sources, and disabling unnecessary client features that might enable automatic deserialization. Security teams should also consider implementing runtime monitoring and anomaly detection to identify potential exploitation attempts. This vulnerability aligns with CWE-502 which specifically addresses deserialization of untrusted data, and maps to ATT&CK technique T1059.007 for remote code execution through deserialization attacks. Organizations should conduct comprehensive vulnerability assessments to identify systems running affected versions and ensure proper patch management procedures are in place to prevent similar vulnerabilities from occurring in the future.
