What is CVE-2025-70327?
CVE-2025-70327 is a critical command injection vulnerability in Totolink X5000r Firmware, published on 23 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
TOTOLINK X5000R v9.1.0cu_2415_B20250515 contains an argument injection vulnerability in the setDiagnosisCfg handler of the /usr/sbin/lighttpd executable. The ip parameter is retrieved via websGetVar and passed to a ping command through CsteSystem without validating if the input starts with a hyphen (-). This allows remote authenticated attackers to inject arbitrary command-line options into the ping utility, potentially leading to a Denial of Service (DoS) by causing excessive resource consumption or prolonged execution.
