Cisco Small Business Series Switches Memory Corruption Vulnerability
A vulnerability in the Secure Sockets Layer (SSL) input packet processor of Cisco Small Business 200, 300, and 500 Series Managed Switches could allow an unauthenticated, remote attacker to cause a memory corruption on an affected device. The vulnerability is due to improper validation of HTTPS packets. An attacker could exploit this vulnerability by sending a malformed HTTPS packet to the management web interface of the affected device. A successful exploit could allow the attacker to cause an unexpected reload of the device, resulting in a denial of service (DoS) condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
