Cisco Wednesday revealed details on two vulnerabilities that could enable remote attackers to gain unauthorized administrative access to wireless LANs. The first affects Cisco's Wireless Control System (WCS), an application for managing lightweight access points and WLAN controllers. Cisco Wednesday issued an advisory outlining numerous vulnerabilities in WCS that could enable remote users to perform a wide range of malicious acts, such as logging in with a default password, obtaining access point encryption keys, launching cross-site scripting attacks, and reading and writing to files in the WCS system.
In an advisory issued Wednesday to subscribers of DeepSight Threat Management System, Symantec rated the severity of the flaw as 8.9 on a 10 point scale and said the vulnerabilities only require access to the WCS application in order to be exploited. A second flaw that came to light Wednesday involves an issue in the Cisco Access Point Web interface that could enable remote attackers to bypass authentication and gain access the administrative interface.
