Detailsinfo

A vulnerability was found in Cisco Wireless LAN Controller Software (Wireless LAN Software) (affected version not known). It has been rated as problematic. Affected by this issue is some unknown functionality of the component Web Interface. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is availability. CVE summarizes:

A vulnerability in the web interface of Cisco Wireless LAN Controller Software could allow a low-privileged, authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability exists due to a failure of the HTTP parsing engine to handle specially crafted URLs. An attacker could exploit this vulnerability by authenticating with low privileges to an affected controller and submitting the crafted URL to the web interface of the affected device. Conversely, an unauthenticated attacker could exploit this vulnerability by persuading a user of the web interface to click the crafted URL. A successful exploit could allow the attacker to cause an unexpected restart of the device, resulting in a DoS condition.

The weakness was published 11/26/2019 as cisco-sa-20191106-wlc-dos as confirmed advisory (Website). The advisory is available at tools.cisco.com. This vulnerability is handled as CVE-2019-15276 since 08/20/2019. The attack may be launched remotely. A simple authentication is required for exploitation. Technical details are unknown but a public exploit is available.

The exploit is available at exploit-db.com. It is declared as proof-of-concept.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at Exploit-DB (47744). If you want to get best quality of vulnerability data, you may have to visit VulDB.
