Cisco Wireless LAN Controller (WLC) Software contains a vulnerability that could allow an unauthenticated, remote attacker to conduct cross-site request forgery attacks on a targeted system. The vulnerability is due to insufficient sanitization of user-supplied input processed by the WLC management web interface of the affected software. An unauthenticated, remote attacker could exploit this vulnerability by convincing a targeted user to follow a malicious link. Successful exploitation could allow the attacker to gain unauthorized access to the affected application, which could be used to conduct further attacks. Cisco confirmed the vulnerability in a security bug report; however, software updates are not available. To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link. Cisco would like to thank security researcher Jacob Holcomb for reporting this vulnerability.
The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.
