InHand Networks IR615 Router

The impact of CVE-2021-38480 is substantial. An attacker exploiting this CSRF vulnerability can gain complete control over the affected IR615 router. This includes the ability to modify network configurations, redirect traffic, install malware, and potentially pivot to other systems on the network. The ability to change administrator credentials allows for persistent access, enabling long-term compromise. Given the router’s role in network connectivity, a successful attack could disrupt services, expose sensitive data, and create a backdoor for future malicious activity. This vulnerability shares similarities with other CSRF exploits where user trust is leveraged to execute unauthorized actions.

Organizations utilizing InHand Networks IR615 routers in their network infrastructure are at risk, particularly those relying on the affected versions for critical network functions. Shared hosting environments where multiple users share a router instance are also at increased risk, as an attacker could potentially exploit the vulnerability through another user's session.

The primary mitigation for CVE-2021-38480 is to upgrade the InHand Networks IR615 Router to a patched firmware version. Unfortunately, a fixed version is not specified in the provided data. As a temporary workaround, implement strict input validation on all web forms within the router’s management portal to prevent malicious commands from being submitted. Consider deploying a Web Application Firewall (WAF) with CSRF protection rules to filter out suspicious requests. Additionally, enforce multi-factor authentication (MFA) for all administrative accounts to add an extra layer of security. After applying any mitigation steps, verify the router’s configuration and security posture to ensure the vulnerability is no longer exploitable.
