Note: Although this vulnerability is in the SSL VPN feature, successful exploitation of this vulnerability would affect all new SSL/TLS sessions to the device, including management sessions.Ĭisco has released software updates that address this vulnerability. Established SSL/TLS connections to the device and SSL/TLS connections through the device are not affected. A reload of the device is required to recover from this condition. A successful exploit could allow the attacker to overwrite a special system memory location, which will eventually result in memory allocation errors for new SSL/TLS sessions to the device, preventing successful establishment of these sessions. The attacker would need to have valid user credentials on the affected device to exploit this vulnerability. An attacker could exploit this vulnerability by opening many SSL VPN sessions to an affected device. The vulnerability is due to incorrect handling of Base64-encoded strings. ! cci: !NCI: Op=BIND, Layer=NDIS, Upper=Tcpip6 Lower=\Device\, Error=00000002Īttached is the Dartbundle troubleshooting zip file.A vulnerability in the Secure Sockets Layer (SSL) VPN feature of Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition that prevents the creation of new SSL/Transport Layer Security (TLS) connections to an affected device.
