CVE-2024-39801
CVE-2024-39801 affects Wavlink AC3000 routers. This buffer overflow vulnerability allows remote attackers to execute arbitrary code via a crafted HTTP request.
CVE-2024-39801 describes multiple buffer overflow vulnerabilities within the qos.cgi qos_settings() function of Wavlink AC3000 M33A8.V5030.210505 routers. A specially crafted HTTP POST request targeting the qos_bandwidth parameter can trigger a stack-based buffer overflow. Although the CVSS score is high (9.1), the SOCRadar Vulnerability Risk Score (SVRS) is 42, indicating a moderate risk, but one that should still be addressed in a timely manner. An authenticated attacker can exploit this vulnerability to potentially execute arbitrary code on the device. This poses a significant risk of device compromise and network intrusion, necessitating prompt patching or mitigation. While not immediately critical, the presence of buffer overflows highlights potential security weaknesses in the device's firmware. Wavlink users should monitor for updates.
Description
CVE-2024-39801 is a critical vulnerability affecting the Wavlink AC3000 M33A8.V5030.210505 router. This vulnerability is a stack-based buffer overflow within the qos.cgi's qos_settings() functionality, specifically within the qos_bandwidth POST parameter. An attacker can exploit this vulnerability by sending a crafted HTTP request, potentially leading to code execution or denial of service. While the CVSS score is 9.1, the SOCRadar Vulnerability Risk Score (SVRS) is 42, indicating a moderate level of risk due to its specific context and the potential impact.
Key Insights
- Remote Code Execution: The vulnerability allows an attacker to execute arbitrary code on the affected device with appropriate privileges, enabling them to gain complete control over the router.
- Authenticated Attack: The vulnerability requires an attacker to be authenticated to the router, meaning it is less likely to be exploited in a mass-exploitation scenario. However, it still poses a serious threat to individual users and organizations.
- Exploit in the Wild: CVE-2024-39801 is actively exploited by hackers in the wild, meaning it's not just a theoretical threat. This emphasizes the urgency of patching the vulnerability.
- Targeted Attacks: The exploitability of CVE-2024-39801 likely makes it attractive for targeted attacks, where attackers aim to compromise specific routers for data exfiltration or network disruption.
Mitigation Strategies
- Patching: Immediately apply the security patch provided by the vendor for CVE-2024-39801. This patch should address the vulnerability and prevent exploitation.
- Network Segmentation: Implementing network segmentation can limit the impact of an attack, even if the router is compromised. It reduces the attacker's access to other devices on the network.
- Change Default Credentials: Ensure that the router's default credentials are changed to strong, unique passwords to make it more difficult for attackers to gain initial access.
- Intrusion Detection Systems (IDS): Deploy IDS solutions to detect potential malicious activities and alert administrators to suspicious traffic.
