The CVE-2015-2849 vulnerability represents a critical sql injection flaw within the ANTlabs InnGate firmware ecosystem affecting multiple device models including IG 3100, InnGate 3.01 E, InnGate 3.10 E, InnGate 3.10 M, SG 4, and SSG 4 devices. This vulnerability specifically targets the main.ant component and manifests when https communication is employed, creating a significant attack surface for remote threat actors. The flaw resides in the improper input validation of the ppli parameter, which serves as the primary vector for malicious sql command injection attempts. The vulnerability demonstrates characteristics consistent with CWE-89 sql injection weakness, where user-supplied data flows directly into sql command execution without adequate sanitization or parameterization measures. This allows attackers to manipulate database queries and potentially gain unauthorized access to sensitive information stored within the device's database systems.
The operational impact of this vulnerability extends beyond simple data theft to encompass full system compromise capabilities. Remote attackers can execute arbitrary sql commands through the vulnerable ppli parameter, potentially leading to complete database manipulation, unauthorized user account creation, data exfiltration, and service disruption. The use of https as the attack vector does not provide adequate protection against this vulnerability, as the flaw exists at the application logic level rather than the transport layer. Attackers can exploit this weakness to escalate privileges, modify system configurations, or establish persistent access points within network infrastructure. The vulnerability affects devices that are commonly deployed in enterprise and industrial network environments, making the potential impact substantial for organizations relying on these security appliances for network protection and access control.
Security practitioners should consider this vulnerability in relation to the mitre attack framework, particularly within the execution and privilege escalation phases where attackers can leverage sql injection to gain deeper system access. The vulnerability's exploitation requires minimal prerequisites beyond network access to the affected devices, making it particularly dangerous in environments where proper network segmentation is lacking. Organizations should implement immediate mitigations including firmware updates from ANTlabs, network access controls to restrict access to affected devices, and monitoring for suspicious sql query patterns. The vulnerability also highlights the importance of input validation and parameterized queries in embedded systems, as outlined in industry best practices for secure coding standards. Additional defensive measures should include regular vulnerability assessments, network traffic monitoring for anomalous sql injection patterns, and implementation of web application firewalls to detect and block malicious payloads targeting this specific vulnerability.
