CVE-2016-9054 in Database Server
Summary
by MITRE
An exploitable stack-based buffer overflow vulnerability exists in the querying functionality of Aerospike Database Server 3.10.0.3. A specially crafted packet can cause a stack-based buffer overflow in the function as_sindex__simatch_list_by_set_binid resulting in remote code execution. An attacker can simply connect to the port to trigger this vulnerability.

The vulnerability identified as CVE-2016-9054 represents a critical stack-based buffer overflow within the Aerospike Database Server version 3.10.0.3 that exposes the system to remote code execution threats. This flaw specifically manifests within the as_sindex__simatch_list_by_set_binid function, which processes querying operations in the database server's secondary index functionality. The vulnerability stems from inadequate input validation mechanisms that fail to properly constrain buffer boundaries during packet processing, creating an exploitable condition that can be triggered through network-based attacks.
The technical exploitation of this vulnerability occurs when a malicious actor sends a specially crafted packet to the Aerospike server port, which then processes the malformed data through the vulnerable function. The stack-based buffer overflow enables attackers to overwrite adjacent memory locations, potentially allowing arbitrary code execution with the privileges of the database server process. This type of vulnerability falls under CWE-121 stack-based buffer overflow classification, which is a well-documented weakness in software security that occurs when data written to a stack buffer exceeds the buffer's allocated size. The attack vector is particularly dangerous because it requires no authentication or prior access to the system, making it a remote exploit that can be initiated from any network location capable of reaching the database server port.
The operational impact of CVE-2016-9054 extends beyond simple remote code execution, as it fundamentally compromises the integrity and confidentiality of the database system. Successful exploitation could enable attackers to access sensitive data stored within the Aerospike database, modify or delete records, escalate privileges, or establish persistent access to the compromised system. The vulnerability affects the core database functionality and could lead to complete system compromise, especially when the Aerospike server operates in environments with high-value data assets or when combined with other exploitation techniques. This weakness aligns with ATT&CK technique T1059 for command and scripting interpreter, as the successful exploitation would likely involve executing malicious code on the target system, and potentially T1078 for valid accounts, if attackers can leverage the compromised system for further lateral movement.
Organizations should immediately implement mitigations including applying the vendor-provided security patches, implementing network segmentation to restrict access to Aerospike server ports, and deploying intrusion detection systems to monitor for suspicious packet patterns. The vulnerability demonstrates the importance of proper input validation and memory management practices in database server software, as well as the necessity of regular security assessments and vulnerability management processes. Additionally, network-level controls such as firewalls and access control lists should be configured to limit exposure of Aerospike services to trusted networks only, while monitoring systems should be enhanced to detect potential exploitation attempts targeting this specific vulnerability class.
