CVE-2022-44197: n/a in n/a
Netgear R7000P V1.3.0.8 is vulnerable to Buffer Overflow via parameter openvpn_server_ip.
AI Analysis
Technical Summary
CVE-2022-44197 is a critical buffer overflow vulnerability identified in the Netgear R7000P router running firmware version 1.3.0.8. The vulnerability arises from improper handling of the 'openvpn_server_ip' parameter, which can be exploited by an unauthenticated remote attacker over the network. Specifically, the buffer overflow (CWE-787) occurs when the input to this parameter exceeds the expected bounds, allowing the attacker to overwrite memory. This can lead to arbitrary code execution, complete compromise of the device, and potentially full control over the router's operating system. The vulnerability has a CVSS 3.1 base score of 9.8, indicating critical severity, with attack vector being network-based (AV:N), no privileges required (PR:N), no user interaction needed (UI:N), and impacts on confidentiality, integrity, and availability all rated high (C:H/I:H/A:H). Although no known exploits are currently reported in the wild, the ease of exploitation combined with the critical impact makes this a significant threat. The affected product is the Netgear R7000P, a popular consumer and small office router model, widely deployed in various regions including Europe. The lack of vendor-provided patches or updates at the time of publication increases the urgency for mitigation. Attackers exploiting this vulnerability could intercept, manipulate, or disrupt network traffic, deploy malware, or pivot into internal networks, severely compromising organizational security.
Potential Impact
For European organizations, the exploitation of CVE-2022-44197 could have severe consequences. The Netgear R7000P is commonly used in small to medium enterprises (SMEs), home offices, and some branch offices, making it a critical point of network ingress and egress. Successful exploitation could lead to full compromise of the router, allowing attackers to intercept sensitive communications, exfiltrate confidential data, disrupt business operations through denial of service, or use the device as a foothold for lateral movement within corporate networks. This is particularly concerning for sectors with high data sensitivity such as finance, healthcare, and government agencies. Additionally, compromised routers can be enlisted into botnets, amplifying the threat landscape. The absence of authentication and user interaction requirements means attacks can be automated and launched remotely without user awareness, increasing the risk of widespread exploitation. Given Europe's stringent data protection regulations (e.g., GDPR), such breaches could also result in significant legal and financial penalties.
Mitigation Recommendations
1. Immediate Network Segmentation: Isolate affected Netgear R7000P devices from critical internal networks to limit potential lateral movement if compromised. 2. Disable OpenVPN Service: If OpenVPN functionality is not essential, disable it on the router to eliminate the attack surface related to the vulnerable parameter. 3. Monitor Network Traffic: Deploy IDS/IPS solutions tuned to detect anomalous traffic patterns or exploitation attempts targeting OpenVPN or unusual packets directed at the router. 4. Firmware Updates and Vendor Communication: Continuously monitor Netgear's official channels for firmware updates or security advisories addressing this vulnerability. Engage with vendor support to obtain any available patches or workarounds. 5. Replace or Upgrade Devices: For environments where patching is not feasible, consider replacing affected routers with models confirmed to be free from this vulnerability or with actively supported firmware. 6. Implement Strong Network Access Controls: Use firewall rules to restrict access to router management interfaces and VPN endpoints only to trusted IP addresses. 7. Incident Response Preparedness: Prepare for potential exploitation by ensuring logs are collected and reviewed regularly, and have an incident response plan tailored to network device compromises. 8. User Awareness: Educate IT staff about the vulnerability specifics and signs of exploitation to enhance detection and response capabilities.
