CVE-2019-1799

Name of the Vulnerable Software and Affected Versions Cisco Wireless LAN Controller (WLC) Software versions prior to 8.2.170.0 Cisco Wireless LAN Controller (WLC) Software versions prior to 8.5.150.0 Cisco Wireless LAN Controller (WLC) Software versions prior to 8.8.100.0

Description A vulnerability in the handling of Inter-Access Point Protocol (IAPP) messages by Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. The vulnerability exists because the software improperly validates input on fields within IAPP messages. An attacker could exploit the vulnerability by sending malicious IAPP messages to an affected device. A successful exploit could allow the attacker to cause the Cisco WLC Software to reload, resulting in a DoS condition.
