CVE-2024-39602
CVE-2024-39602 is a critical vulnerability in Wavlink AC3000 routers allowing remote attackers to execute arbitrary commands. This command execution flaw is located within the nas.cgi set_nas() function. By sending a crafted HTTP request, an authenticated attacker can exploit this security hole. While the CVSS score indicates high severity, the SOCRadar Vulnerability Risk Score (SVRS) of 42 suggests a moderate level of active real-world threat, despite being tagged "In The Wild". This means while the vulnerability is being exploited, the scale isn't deemed critical at the moment. Immediate patching is recommended to prevent unauthorized access and potential system compromise. Successful exploitation could lead to complete control of the affected router.
Description
CVE-2024-39602 is an external config control vulnerability affecting the nas.cgi set_nas() functionality of Wavlink AC3000 M33A8.V5030.210505. This vulnerability allows an attacker to execute arbitrary commands on the affected device by sending a specially crafted HTTP request.
While the CVSS score is high at 9.1, the SVRS score of 42 indicates that this vulnerability might not be as urgently critical as the CVSS score suggests. It is essential to remember that the SVRS considers a wider range of factors than just the technical severity of the vulnerability.
Key Insights
- Authenticated HTTP request: The exploit requires authentication, suggesting that the attacker might need access to the affected device's network. However, the potential for unauthorized access and control over the device remains a significant concern.
- Arbitrary command execution: The vulnerability allows an attacker to execute arbitrary commands, granting them full control over the affected device. This could potentially be used to compromise the device, steal sensitive data, or launch further attacks.
- Active exploitation: The CVE is tagged "In The Wild," indicating that this vulnerability is actively exploited by hackers. This suggests that the threat actors might be actively searching for vulnerable devices and exploiting them for their gain.
Mitigation Strategies
- Update firmware: Update the firmware on your Wavlink AC3000 M33A8.V5030.210505 device to the latest version to patch this vulnerability. The latest firmware versions are typically available on the vendor's website.
- Restrict network access: Limit network access to the affected device to trusted sources. Consider implementing a firewall to prevent unauthorized access and restrict communication to essential services.
- Implement strong authentication: Implement strong authentication measures, such as multi-factor authentication (MFA), to protect against unauthorized access to the device.
- Monitor security logs: Regularly monitor security logs for suspicious activity and potential signs of exploitation.
