Technical Analysis

CVE-2022-40486 is a high-severity vulnerability affecting the TP Link Archer AX10 V1 router firmware version 1.3.1 Build 20220401 Rel. 57450(5553). The vulnerability allows an authenticated attacker to execute arbitrary code on the device by leveraging a crafted backup file. This is a classic example of code injection through improper handling of backup file contents, classified under CWE-94 (Improper Control of Generation of Code). The attack vector is network-based (AV:N), requiring low attack complexity (AC:L) but does require the attacker to have some level of privileges (PR:L) on the device, meaning the attacker must be authenticated. No user interaction is needed (UI:N), and the vulnerability affects confidentiality, integrity, and availability (C:H/I:H/A:H) of the device. Exploiting this vulnerability could allow an attacker to gain full control over the router, potentially leading to interception or manipulation of network traffic, persistent backdoors, or disruption of network services. Although no known exploits are currently reported in the wild, the high CVSS score of 8.8 indicates a significant risk if exploited. The vulnerability impacts the firmware's backup and restore functionality, which is commonly used for configuration management, making it a critical attack surface. The lack of an official patch link suggests that remediation may require manual firmware updates or vendor intervention.

Potential Impact

For European organizations, this vulnerability poses a substantial risk, especially for small and medium enterprises (SMEs) and home office environments that commonly use consumer-grade routers like the TP Link Archer AX10. Compromise of these routers can lead to interception of sensitive communications, unauthorized network access, and lateral movement within corporate networks. Given the high confidentiality, integrity, and availability impact, attackers could exfiltrate sensitive data, disrupt business operations, or use compromised routers as footholds for further attacks. The risk is heightened in sectors with stringent data protection requirements under GDPR, where breaches involving personal data could lead to regulatory penalties. Additionally, the vulnerability could be exploited to launch attacks on critical infrastructure or supply chains if these routers are deployed in such environments. The requirement for authentication limits exploitation to insiders or attackers who have already gained some access, but this does not diminish the threat, as phishing or credential theft could facilitate such access.

Mitigation Recommendations

Organizations should immediately verify if TP Link Archer AX10 V1 routers with the specified firmware version are in use. If so, they should seek firmware updates from TP Link that address this vulnerability or apply any available patches. In the absence of official patches, consider temporarily disabling the backup and restore functionality or restricting access to the router's management interface to trusted network segments only. Implement strong authentication mechanisms, including changing default credentials and enforcing complex passwords to reduce the risk of unauthorized access. Network segmentation should be employed to isolate routers from critical systems. Monitoring network traffic for unusual activity and enabling logging on routers can help detect exploitation attempts. Additionally, organizations should educate users about the risks of credential compromise and enforce multi-factor authentication where possible for device management interfaces. Regularly auditing device firmware versions and configurations is essential to maintain security posture.
