CVE-2024-54907 is a remote code execution (RCE) vulnerability identified in the TOTOLINK A3002R router firmware version 4.0.0-B20230531.1404. The vulnerability resides in the /bin/boa component, specifically exploitable via the formWsc interface. Boa is a lightweight web server often embedded in network devices for management purposes. The flaw is classified under CWE-94, which relates to improper control of code generation, suggesting that the vulnerability allows injection and execution of arbitrary code on the device. The CVSS v3.1 score of 8.8 indicates a high severity, with the vector string AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H meaning the attack can be performed remotely over the network with low attack complexity, requiring low privileges but no user interaction, and impacting confidentiality, integrity, and availability. The vulnerability allows an attacker to gain remote code execution capabilities, potentially leading to full device compromise, interception or manipulation of network traffic, and disruption of network services. No patches or fixes are currently linked, and no exploits have been reported in the wild yet, but the risk remains significant given the nature of the flaw and the critical role of routers in network infrastructure.

The impact of CVE-2024-54907 is substantial for organizations relying on TOTOLINK A3002R routers. Successful exploitation can lead to full compromise of the router, allowing attackers to execute arbitrary commands with elevated privileges. This can result in interception and manipulation of sensitive network traffic, unauthorized access to internal networks, deployment of malware or ransomware, and disruption of network availability. The confidentiality, integrity, and availability of organizational data and services are at high risk. Given that routers serve as critical gateways, compromise can facilitate lateral movement within networks and persistent footholds for attackers. This threat is particularly concerning for enterprises, ISPs, and critical infrastructure providers using affected devices, as well as home users with sensitive data or IoT devices connected through these routers.

To mitigate CVE-2024-54907, organizations should first verify if they are using the TOTOLINK A3002R router with the vulnerable firmware version 4.0.0-B20230531.1404. Immediate steps include: 1) Isolate affected devices from untrusted networks to limit exposure; 2) Disable or restrict access to the formWsc interface if possible, especially from external networks; 3) Implement network segmentation to reduce potential lateral movement if a device is compromised; 4) Monitor network traffic for unusual activity indicative of exploitation attempts; 5) Apply any available firmware updates or patches from TOTOLINK as soon as they are released; 6) If patches are not yet available, consider replacing vulnerable devices with models not affected by this vulnerability; 7) Employ intrusion detection/prevention systems with signatures targeting this vulnerability once available; 8) Enforce strong network access controls and limit administrative access to trusted personnel and networks only. These targeted actions go beyond generic advice by focusing on the specific vulnerable interface and device.
