CVE-2025-60671
Last modified
CVE-2025-60671 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. A command injection vulnerability exists in the D-Link DIR-823G router firmware DIR823G_V1.0.2B05_20181207.bin in the timelycheck and sysconf binaries, which process the /var/system/linux_vlan_reinit file. The vulnerability occurs because content read from this file is only partially validated for a prefix and then formatted using vsnprintf() before being executed with system(), allowing an attacker with write access to /var/system/linux_vlan_reinit to execute arbitrary commands on the device.. EPSS estimates a 1.33% chance of exploitation in the next 30 days.
