Synopsis
The remote device is missing vendor-supplied security patches.Description
According to its self-reported version, the remote Cisco Wireless LAN Controller (WLC) device is affected by multiple vulnerabilities :- A denial of service vulnerability exists within the web-based device management interface of AireOS due to the presence of unsupported URLs that are not generally accessible from and supported by the management interface. An unauthenticated, remote attacker can exploit this, via a crafted HTTP request to one of these URLs, to cause the device to reload. (CVE-2016-1362)
- A buffer overflow condition exists in the redirection functionality due to a failure to properly validate user-supplied input when handling HTTP requests. An unauthenticated, remote attacker can exploit this, via a crafted request, to execute arbitrary code.
(CVE-2016-1363)
- A denial of service vulnerability exists due to improper handling of crafted Bonjour traffic, which allows an unauthenticated, remote attacker to cause the device to reload. (CVE-2016-1364)
