CVE-2024-41314 is a command injection vulnerability identified in the TOTOLINK A6000R router firmware version V1.0.1-B20201211.2000. The vulnerability resides in the vif_disable function, specifically through the iface parameter, which is improperly sanitized or validated, allowing an attacker to inject and execute arbitrary system commands. This type of vulnerability falls under CWE-78 (Improper Neutralization of Special Elements used in an OS Command), which can lead to full system compromise. The CVSS 3.1 base score of 6.8 reflects a medium severity rating, with the vector indicating that the attack requires an adjacent network attacker with high privileges (authentication) but no user interaction. The impact on confidentiality, integrity, and availability is high, meaning successful exploitation can lead to unauthorized data access, modification, or denial of service. No patches or fixes have been released at the time of publication, and no known exploits have been observed in the wild. The vulnerability affects a specific router model commonly used in home and small office environments, which could be leveraged as a foothold for further network intrusion or lateral movement.

The impact of CVE-2024-41314 is significant for organizations using the TOTOLINK A6000R router, as successful exploitation allows an authenticated attacker to execute arbitrary commands on the device. This can lead to full compromise of the router, enabling attackers to intercept, modify, or disrupt network traffic, exfiltrate sensitive information, or launch further attacks within the internal network. Given the router’s role as a network gateway, this vulnerability could undermine the confidentiality, integrity, and availability of connected systems. Small and medium enterprises, as well as home users relying on this device, are particularly vulnerable. The requirement for authentication limits the attack surface but does not eliminate risk, especially if credentials are weak or compromised. The absence of patches increases exposure duration, and the lack of known exploits suggests potential for future exploitation once details become widely known.

To mitigate CVE-2024-41314, organizations should immediately restrict access to the router’s management interface to trusted network segments and users, employing network segmentation and firewall rules to limit exposure. Strong authentication mechanisms, including complex passwords and, if supported, multi-factor authentication, should be enforced to reduce the risk of credential compromise. Monitoring and logging of administrative access and unusual command execution attempts should be implemented to detect potential exploitation attempts. Until an official patch is released, consider disabling or limiting the use of the vif_disable function if possible, or replacing the affected device with a more secure alternative. Regularly check for firmware updates from TOTOLINK and apply them promptly once available. Additionally, educating users about secure credential practices and maintaining an inventory of vulnerable devices will aid in risk management.
