What is CVE-2024-5227?

The TP-Link Omada ER605 router is susceptible to a command injection vulnerability that enables network-adjacent attackers to execute arbitrary code. This exploit does not require authentication, making it particularly concerning for devices configured with a PPTP VPN using LDAP authentication. The vulnerability originates from the inadequate validation of the username parameter within the pppd endpoint, allowing attackers to manipulate system calls and execute code with root privileges. Proper configuration and security measures are essential to mitigate this risk.
