This vulnerability resides within the command line interface of AOS-CX network devices, specifically targeting the parameter handling mechanism of certain CLI commands. The flaw represents a command injection vulnerability that arises from inadequate input validation and sanitization of command parameters. An attacker with minimal privileges and remote access capabilities can exploit this weakness to inject arbitrary commands that will be executed within the context of the affected system. The vulnerability stems from insufficient filtering of user-supplied input, allowing malicious payloads to bypass normal command parsing mechanisms and be interpreted as legitimate commands.
The technical implementation of this vulnerability aligns with CWE-77 which categorizes command injection flaws as weaknesses where untrusted data is incorporated into command structures without proper validation. The attack vector involves a low-privilege authenticated user who can leverage this vulnerability to execute unauthorized commands on the network device. This represents a significant security risk as it allows for privilege escalation and potential lateral movement within the network infrastructure. The vulnerability affects the core CLI functionality and could enable an attacker to gain unauthorized access to sensitive network configurations, modify device settings, or even establish persistent access points.
Operationally, this vulnerability presents a critical threat to network security posture as it enables remote exploitation from authenticated users with minimal privileges. The impact extends beyond simple command execution to potentially compromise the entire network infrastructure, as network devices often serve as critical control points for network operations. Attackers could leverage this vulnerability to manipulate routing tables, disable security features, or gain access to other network segments. The remote nature of the attack means that adversaries do not require physical access to the devices, making detection and prevention more challenging. This vulnerability also aligns with several ATT&CK techniques including T1059 Command and Scripting Interpreter and T1566 Phishing, as attackers may use social engineering to gain initial access before exploiting this command injection flaw.
Mitigation strategies should focus on implementing robust input validation and sanitization mechanisms for all CLI command parameters. Network administrators should immediately apply vendor-provided patches and updates to address this vulnerability. Configuration management practices should enforce strict access controls and limit user privileges to the minimum required for operational tasks. Network segmentation and monitoring solutions should be enhanced to detect anomalous command execution patterns. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in network infrastructure components. The implementation of secure coding practices and comprehensive input validation should be enforced across all network device firmware and software components to prevent similar command injection vulnerabilities from emerging in future releases.
