Linksys RE Series, OS Command Injection, CVE-2025-5442 (Critical)

Listen to this Post

How the CVE Works

The vulnerability exists in the `RP_pingGatewayByBBS` function within `/goform/RP_pingGatewayByBBS` in Linksys RE6500, RE6250, RE6300, RE6350, RE7000, and RE9000 firmware versions 1.0.013.001 to 1.2.07.001. Attackers can exploit this flaw by manipulating the `ip/nm/gw` parameters to inject arbitrary OS commands due to insufficient input sanitization. The attack is remotely executable, allowing unauthenticated threat actors to execute malicious commands on the device with root privileges. The publicly disclosed exploit leverages crafted HTTP requests to trigger command injection, potentially leading to full device compromise.
