CVE-2021-38703
Last modified
CVE-2021-38703 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. Wireless devices running certain Arcadyan-derived firmware (such as KPN Experia WiFi 1.00.15) do not properly sanitise user input to the syslog configuration form. An authenticated remote attacker could leverage this to alter the device configuration and achieve remote code execution. EPSS estimates a 4.32% chance of exploitation in the next 30 days.
