CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability classified as problematic was found in Cisco Wireless LAN Controller up to 8.2/8.5/8.8 (Wireless LAN Software). This vulnerability affects some unknown processing of the component IAPP Message Handler. The manipulation with an unknown input leads to a resource management vulnerability. The CWE definition for the vulnerability is CWE-399. As an impact it is known to affect availability. CVE summarizes:

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 exist 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. Software versions prior to 8.2.170.0, 8.5.150.0, and 8.8.100.0 are affected.

The bug was discovered 04/17/2019. The weakness was shared 04/18/2019 with Cisco as cisco-sa-20190417-wlc-iapp as confirmed advisory (Website). The advisory is shared for download at tools.cisco.com. This vulnerability was named CVE-2019-1800 since 12/06/2018. Access to the local network is required for this attack to succeed. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k. The commercial vulnerability scanner Qualys is able to test this issue with plugin 316410 (Cisco Wireless LAN Controller Software IAPP Message Handling Denial of Service Vulnerabilities(cisco-sa-20190417-wlc-iapp)).

Upgrading to version 8.2.170.0, 8.5.150.0 or 8.8.100.0 eliminates this vulnerability.
