CVE-2025-44868: n/a in n/a
Wavlink WL-WN530H4 20220801 was found to contain a command injection vulnerability in the ping_test function of the adm.cgi via the pingIp parameter. This vulnerability allows attackers to execute arbitrary commands via a crafted request.
AI Analysis
Technical Summary
CVE-2025-44868 is a critical command injection vulnerability identified in the Wavlink WL-WN530H4 device firmware version 20220801. The flaw exists in the ping_test function within the adm.cgi interface, specifically via the pingIp parameter. This vulnerability allows an unauthenticated remote attacker to execute arbitrary system commands by sending a specially crafted HTTP request to the vulnerable CGI endpoint. The root cause is improper input validation or sanitization of the pingIp parameter, which is exploited to inject shell commands (CWE-77). The CVSS v3.1 base score is 9.8, indicating a critical severity with network attack vector, no privileges required, no user interaction, and full impact on confidentiality, integrity, and availability. The vulnerability affects the device’s administrative interface, which is typically exposed on local networks or potentially on the internet if misconfigured. Exploitation can lead to complete system compromise, allowing attackers to control the device, pivot into internal networks, intercept or manipulate traffic, and disrupt network availability. No patches or official mitigations have been published yet, and no known exploits are currently reported in the wild. However, the high severity and ease of exploitation make this a significant threat, especially for organizations relying on Wavlink WL-WN530H4 devices in their network infrastructure.
Potential Impact
For European organizations, this vulnerability poses a severe risk to network security and operational continuity. Wavlink devices are commonly used in small to medium enterprise environments and home offices, which may be part of larger corporate or critical infrastructure networks. Successful exploitation could lead to unauthorized access to internal networks, data breaches involving sensitive or personal data protected under GDPR, and disruption of business operations. The ability to execute arbitrary commands remotely without authentication means attackers can deploy malware, create persistent backdoors, or launch further attacks against connected systems. This risk is exacerbated in environments where these devices are exposed to the internet or poorly segmented from critical assets. Additionally, compromised devices could be leveraged as part of botnets or for lateral movement within organizational networks, increasing the scope of potential damage. The lack of available patches increases the urgency for immediate mitigation to prevent exploitation.
Mitigation Recommendations
1. Immediate network-level controls: Restrict access to the Wavlink WL-WN530H4 administrative interface by implementing firewall rules to allow management only from trusted internal IP addresses or VPNs. 2. Disable remote administration features if not required, or ensure they are not exposed to the internet. 3. Monitor network traffic for unusual requests targeting the adm.cgi endpoint, especially those containing suspicious pingIp parameter values indicative of command injection attempts. 4. Segment networks to isolate vulnerable devices from critical infrastructure and sensitive data environments. 5. Regularly audit and update device firmware; although no patch is currently available, maintain contact with the vendor for updates or advisories. 6. Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics capable of detecting command injection attempts against CGI interfaces. 7. Educate IT and security staff about this vulnerability to ensure rapid response to any suspicious activity. 8. Consider replacing vulnerable devices with alternatives from vendors with stronger security track records if timely patches are not forthcoming.
