CVE-2024-23059: n/a in n/a
TOTOLINK A3300R V17.0.0cu.557_B20221024 was discovered to contain a command injection vulnerability via the username parameter in the setDdnsCfg function.
AI Analysis
Technical Summary
CVE-2024-23059 is a critical command injection vulnerability identified in the TOTOLINK A3300R router firmware version V17.0.0cu.557_B20221024. The vulnerability exists in the setDdnsCfg function, specifically via the username parameter. Command injection vulnerabilities occur when untrusted input is passed to a system shell or command interpreter without proper sanitization, allowing an attacker to execute arbitrary commands on the affected device. In this case, an attacker can exploit the username parameter to inject malicious commands, potentially gaining full control over the router. The CVSS v3.1 score of 9.8 reflects the high severity, indicating that the vulnerability is remotely exploitable over the network (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and impacts confidentiality, integrity, and availability (C:H/I:H/A:H) of the device. The vulnerability is classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command). No patches or fixes have been publicly disclosed yet, and no known exploits are currently reported in the wild. However, the critical nature of this flaw means that exploitation could lead to complete compromise of the router, enabling attackers to intercept or manipulate network traffic, deploy malware, or use the device as a pivot point for further attacks within the network.
Potential Impact
For European organizations, the impact of this vulnerability is significant. Routers like the TOTOLINK A3300R are often used in small to medium enterprises and home office environments, which may lack robust security monitoring. Exploitation could lead to unauthorized access to internal networks, data interception, and disruption of business operations. Given the criticality, attackers could leverage this vulnerability to establish persistent footholds, exfiltrate sensitive information, or launch further attacks such as lateral movement or ransomware deployment. The compromise of network infrastructure devices also undermines trust in network security, potentially affecting compliance with European data protection regulations such as GDPR. Additionally, the disruption of availability could impact business continuity, especially for organizations relying on these routers for internet connectivity or VPN access.
Mitigation Recommendations
Immediate mitigation steps include isolating affected devices from untrusted networks and disabling remote management interfaces if enabled. Network administrators should monitor network traffic for unusual activity indicative of exploitation attempts. Since no official patch is currently available, organizations should consider replacing affected TOTOLINK A3300R devices with models from vendors that provide timely security updates. Employing network segmentation can limit the impact of a compromised router. Additionally, implementing strict access controls and using VPNs with strong authentication can reduce exposure. Regularly auditing router configurations and firmware versions across the network is essential. Organizations should also subscribe to vendor advisories and CVE databases to apply patches promptly once released. For critical environments, deploying intrusion detection systems (IDS) capable of detecting command injection patterns may provide early warning of exploitation attempts.
