CVE-2024-25290Network attack vector

Authenticated root command execution via unsanitized userName

Published May 2, 2024 · Updated Aug 1, 2024

Command injection in Casa Systems NL1901ACV before R6B033 allows remote authenticated users to execute arbitrary commands as root. The add function uses its userName parameter for command execution without sufficient input sanitization. Authenticated web-interface access is required, and successful exploitation grants control over the gateway, including its traffic and installed software.
