The vulnerability CVE-2024-23058 affects the TOTOLINK A3300R router firmware version V17.0.0cu.557_B20221024. It is a command injection flaw categorized under CWE-78, located in the setTr069Cfg function, specifically through the 'pass' parameter. This parameter is improperly sanitized, allowing attackers to inject and execute arbitrary system commands remotely. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, making it highly dangerous. The CVSS v3.1 base score is 9.8, reflecting its critical nature with attack vector network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and full impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Exploiting this flaw could allow attackers to take full control of the affected router, manipulate configurations, intercept or redirect traffic, or launch further attacks within the network. As of the publication date, no patches or official fixes have been released, and no active exploitation has been reported. The vulnerability affects a widely deployed consumer and small business router model, which may be present in many home and enterprise environments worldwide.

The impact of CVE-2024-23058 is severe for organizations using the TOTOLINK A3300R router, as successful exploitation leads to complete compromise of the device. Attackers could gain unauthorized access to network traffic, modify router settings, install persistent malware, or use the device as a foothold to attack internal networks. This threatens confidentiality by exposing sensitive data, integrity by allowing unauthorized configuration changes, and availability by potentially disrupting network connectivity. Enterprises relying on these routers for critical network functions or remote management are particularly vulnerable. The lack of authentication and user interaction requirements lowers the barrier for exploitation, increasing the risk of automated attacks and widespread compromise. The absence of patches heightens urgency for mitigation. Overall, this vulnerability could lead to significant operational disruption, data breaches, and loss of trust in network infrastructure.

To mitigate CVE-2024-23058, organizations should immediately isolate affected TOTOLINK A3300R routers from untrusted networks, especially the internet, to prevent remote exploitation. Disable or restrict TR-069 management services if not required, as the vulnerability resides in the setTr069Cfg function. Employ network segmentation to limit access to management interfaces and monitor network traffic for unusual command injection attempts targeting the 'pass' parameter. Use firewall rules to block unauthorized access to router management ports. Regularly audit router firmware versions and configurations to identify vulnerable devices. Until an official patch is released, consider replacing affected routers with models from vendors with timely security updates. Additionally, implement intrusion detection systems (IDS) with signatures for command injection patterns and maintain strong network monitoring to detect exploitation attempts early. Engage with TOTOLINK support channels for updates and patches.
