CVE-2024-42740Public exploit

Authenticated command execution via unsanitized LED setting

Published Aug 13, 2024 · Updated Aug 13, 2024

OS command injection in TOTOLINK X5000R Firmware 9.1.0cu.2350_b20230313 allows remote authenticated users to execute arbitrary commands. In setLedCfg, the enable parameter reaches Uci_set_str unchecked; Uci_Set_Str embeds it in a uci shell command that CsteSystem passes to execv. Access to the router's authenticated management interface on the adjacent network is required, after which injected commands run with the CGI service's privileges.
