The vulnerabilities exist because the software improperly validates input on fields within IAPP messages. An attacker could exploit the vulnerabilities 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. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
