How the CVE Works
The vulnerability in Linksys RE6500, RE6250, RE6300, RE6350, RE7000, and RE9000 routers stems from improper input sanitization in the `ssid1MACFilter` function within /goform/ssid1MACFilter. Attackers can manipulate the `apselect_%d/newap_text_%d` arguments to inject arbitrary OS commands via crafted HTTP requests. Since the function processes these inputs unsafely, remote attackers can execute malicious commands with root privileges, leading to full device compromise. The exploit is remotely triggerable, requiring no user interaction, and has been publicly disclosed, increasing its risk.
