CVE-2022-44201: n/a in n/a
D-Link DIR823G 1.02B05 is vulnerable to Commad Injection.
AI Analysis
Technical Summary
CVE-2022-44201 is a critical command injection vulnerability affecting the D-Link DIR823G router, specifically version 1.02B05. Command injection vulnerabilities (CWE-78) allow an attacker to execute arbitrary commands on the underlying operating system of the affected device. In this case, the vulnerability enables remote attackers to execute system-level commands without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The attack vector is network-based, meaning exploitation can occur remotely over the network without requiring physical access or prior credentials. The vulnerability impacts confidentiality, integrity, and availability (all rated high), allowing an attacker to potentially take full control of the device, intercept or manipulate network traffic, disrupt network services, or pivot to other internal systems. The lack of available patches or vendor-provided mitigations at the time of publication increases the risk. Although no known exploits in the wild have been reported yet, the high severity and ease of exploitation make this a significant threat to users of the affected router model. The vulnerability is particularly dangerous because routers serve as critical network infrastructure, and compromise can lead to widespread network disruption or data breaches.
Potential Impact
For European organizations, the impact of this vulnerability can be substantial. The D-Link DIR823G router is commonly used in small to medium-sized enterprises and residential environments, which means that many organizations could be using this device as their primary gateway to the internet. Exploitation could lead to unauthorized access to internal networks, interception of sensitive communications, and disruption of business operations. Given the critical nature of the vulnerability, attackers could deploy malware, create persistent backdoors, or launch further attacks against connected systems. This is especially concerning for sectors with high security requirements such as finance, healthcare, and government agencies. Additionally, compromised routers could be leveraged as part of botnets for large-scale distributed denial-of-service (DDoS) attacks, impacting not only the victim organization but also broader internet infrastructure. The absence of authentication and user interaction requirements lowers the barrier for attackers, increasing the likelihood of exploitation in the European context where remote attacks are common.
Mitigation Recommendations
1. Immediate replacement or isolation of affected D-Link DIR823G 1.02B05 routers is recommended if no firmware update is available. 2. Network segmentation should be employed to isolate vulnerable routers from critical internal systems to limit potential lateral movement. 3. Monitor network traffic for unusual outbound connections or command-and-control activity that could indicate exploitation attempts. 4. Implement strict firewall rules to restrict inbound management access to the router from untrusted networks. 5. Use intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics targeting command injection attempts on router management interfaces. 6. Regularly audit and inventory network devices to identify any instances of the affected router model. 7. Engage with D-Link support channels to obtain any forthcoming patches or advisories and apply updates promptly once available. 8. Educate network administrators about the risks of unmanaged or outdated network devices and enforce policies for timely updates and replacements.
