CVE-2019-1797 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. A vulnerability in the web-based management interface of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on the device with the privileges of the user, including modifying the device configuration. The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. EPSS estimates a 0.74% chance of exploitation in the next 30 days.

Description

A vulnerability in the web-based management interface of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on the device with the privileges of the user, including modifying the device configuration. The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading an interface user to follow a crafted link. A successful exploit could allow the attacker to perform arbitrary actions on the device with the privileges of the user. Software versions prior to 8.3.150.0, 8.5.135.0, and 8.8.100.0 are affected.
