Multiple Cisco products incorporate a version of the OpenSSL package affected by a vulnerability that could allow an unauthenticated, remote attacker to retrieve memory in chunks of 64 kilobytes from a connected client or server.

The vulnerability is due to a missing bounds check in the handling of the Transport Layer Security (TLS) heartbeat extension. An attacker could exploit this vulnerability by implementing a malicious TLS or Datagram Transport Layer Security (DTLS) client, if trying to exploit the vulnerability on an affected server, or a malicious TLS or DTLS server, if trying to exploit the vulnerability on an affected client. An exploit could send a specially crafted TLS or DTLS heartbeat packet to the connected client or server. An exploit could allow the attacker to disclose a limited portion of memory from a connected client or server for every heartbeat packet sent. The disclosed portions of memory could contain sensitive information that may include private keys and passwords.

Please note that the devices that are affected by this vulnerability are the devices acting as an SSL server terminating SSL connections or devices acting as an SSL Client initiating an SSL connection. Devices that are simply traversed by SSL traffic without terminating it are not affected.

This advisory will be updated as additional information becomes available. Cisco will release free software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities may be available. This advisory is available at the following link:

Cisco Adaptive Security Appliance (ASA) Software is affected by the following vulnerabilities:

  • Cisco ASA ASDM Privilege Escalation Vulnerability
  • Cisco ASA SSL VPN Privilege Escalation Vulnerability
  • Cisco ASA SSL VPN Authentication Bypass Vulnerability
  • Cisco ASA SIP Denial of Service Vulnerability
These vulnerabilities are independent of one another; a release that is affected by one of the vulnerabilities may not be affected by the others.

Successful exploitation of the Cisco ASA ASDM Privilege Escalation Vulnerability and the Cisco ASA SSL VPN Privilege Escalation Vulnerability may allow an attacker or an unprivileged user to elevate privileges and gain administrative access to the affected system.

Successful exploitation of the Cisco ASA SSL VPN Authentication Bypass Vulnerability may allow an attacker to obtain unauthorized access to the internal network via SSL VPN.

Successful exploitation of the Cisco ASA SIP Denial of Service Vulnerability may cause the exhaustion of available memory. This may cause system instability and in some cases lead to a reload of the affected system, creating a denial of service (DoS) condition.

Cisco has released free software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available for some of the vulnerabilities. This advisory is available at the following link:

A vulnerability in the Secure Sockets Layer (SSL) VPN subsystem of Cisco IOS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition.

The vulnerability is due to a failure to process certain types of HTTP requests. To exploit the vulnerability, an attacker could submit crafted requests designed to consume memory to an affected device. An exploit could allow the attacker to consume and fragment memory on the affected device. This may cause reduced performance, a failure of certain processes, or a restart of the affected device.

Cisco has released free software updates that address this vulnerability. There are no workarounds to mitigate this vulnerability.

Wed, 26 Mar 2014 23:00:00 -0400

A vulnerability in the Internet Key Exchange Version 2 (IKEv2) module of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of the affected device that would lead to a denial of service (DoS) condition.

The vulnerability is due to how an affected device processes certain malformed IKEv2 packets. An attacker could exploit this vulnerability by sending malformed IKEv2 packets to an affected device to be processed. An exploit could allow the attacker to cause a reload of the affected device that would lead to a DoS condition.

Although IKEv2 is automatically enabled on Cisco IOS Software and Cisco IOS XE Software devices when the Internet Security Association and Key Management Protocol (ISAKMP) is enabled, the vulnerability can be triggered only by sending a malformed IKEv2 packet.

Only IKEv2 packets can trigger this vulnerability.

Cisco has released free software updates that address this vulnerability. There are no workarounds to mitigate this vulnerability.

A vulnerability in the Resource Reservation Protocol (RSVP) feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to trigger an interface queue wedge on the affected device.

The vulnerability is due to improper parsing of UDP RSVP packets. An attacker could exploit this vulnerability by sending UDP port 1698 RSVP packets to the vulnerable device. An exploit could cause Cisco IOS Software and Cisco IOS XE Software to incorrectly process incoming packets, resulting in an interface queue wedge, which can lead to loss of connectivity, loss of routing protocol adjacency, and other denial of service (DoS) conditions.
