CVE-2024-57211 is a command injection vulnerability identified in the TOTOLINK A6000R router firmware version V1.0.1-B20201211.2000. The vulnerability resides in the enable_wsh function, specifically through the modifyOne parameter, which fails to properly sanitize user input. This allows an attacker with at least low-level privileges (PR:L) and remote access (AV:A) to inject and execute arbitrary system commands on the device without requiring user interaction (UI:N). The vulnerability is classified under CWE-77, indicating improper neutralization of special elements used in a command ('Command Injection'). The CVSS v3.1 base score is 8.0, reflecting high severity due to the potential for complete compromise of the device’s confidentiality, integrity, and availability. Exploitation could lead to unauthorized control over the router, enabling attackers to intercept or manipulate network traffic, disrupt services, or pivot into internal networks. No patches or public exploits are currently reported, but the risk remains significant given the device’s role in network infrastructure and the ease of exploitation. The vulnerability affects a specific firmware version, and organizations should verify their device versions to assess exposure.

The impact of CVE-2024-57211 is substantial for organizations relying on TOTOLINK A6000R routers. Successful exploitation can lead to full device compromise, allowing attackers to execute arbitrary commands with elevated privileges. This can result in interception or manipulation of network traffic, disruption of internet connectivity, and potential lateral movement within internal networks. Confidential data passing through the router could be exposed or altered, undermining data integrity and privacy. The availability of network services could be degraded or completely denied, impacting business operations. Given the router’s role as a gateway device, the vulnerability poses a critical risk to organizational security posture, especially in environments with remote management enabled. Although no known exploits are currently in the wild, the vulnerability’s characteristics make it a prime target for attackers seeking to gain persistent access or disrupt network operations.

To mitigate CVE-2024-57211, organizations should first verify if their TOTOLINK A6000R routers are running the vulnerable firmware version V1.0.1-B20201211.2000. Since no official patches are currently available, immediate steps include disabling remote management interfaces or restricting access to trusted IP addresses only. Network segmentation should be enforced to limit exposure of the router’s management interface to untrusted networks. Implement strict input validation and monitoring on network devices where possible to detect anomalous command injection attempts. Employ network intrusion detection systems (NIDS) to identify suspicious traffic patterns targeting the modifyOne parameter or enable_wsh function. Regularly check for firmware updates from TOTOLINK and apply them promptly once released. Additionally, consider deploying compensating controls such as VPNs for remote management and multi-factor authentication to reduce the risk of unauthorized access. Maintain comprehensive logging and alerting to detect potential exploitation attempts early.
