Version Summary:Multiple Cisco products contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service condition. Updates are not available.
 
 
Description
A vulnerability in the integration of the ActiveMQ component used in products based on Common Services could allow an unauthenticated, remote attacker to consume available memory and cause a denial of service (DoS) condition.

The vulnerability is due to improper handling of multiple TCP requests targeting some services. An attacker could exploit this vulnerability by opening several concurrent TCP sessions. A full TCP three-way handshake is needed to exploit this vulnerability. An exploit could allow the attacker to consume available memory, causing some processes to hang or crash.

Cisco has confirmed the vulnerability in a security notice; however, software updates are not available.
 
Warning Indicators
At the time this alert was first published, the following Cisco products are affected:
  • Cisco Security Manager version 4.2 and prior
  • Cisco Unified Operations Manager version 8.6 and prior
  • Cisco Unified Service Monitor version 8.6 and prior
  • Cisco Prime LAN Management Solution (LMS) version 4.2.3 and prior
Later releases of the affected Cisco products may also be affected.
 
IntelliShield Analysis
To exploit this vulnerability, it is likely that an attacker would need access to trusted, internal networks in which the targeted device may reside in order to send multiple TCP request to such device. This access requirement limits the likelihood of a successful exploit.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
 
Vendor Announcements
Cisco has released a security notice at the following link: CVE-2013-5488

Customers are advised to consult Cisco bug IDs CSCuh54766, CSCuh01267, CSCuh95976, and CSCuh95969 for the most complete list of affected product versions.
 
Impact
An unauthenticated, remote attacker could exploit this vulnerability to cause an affected device to consume excessive amounts of memory resources, resulting in a DoS condition.
 
Technical Information
The vulnerability is due to improper handling of multiple TCP requests by common services running on an affected device.

An unauthenticated, remote attacker could exploit this vulnerability by generating multiple TCP requests, which would open several concurrent TCP sessions. If successful, the attacker could cause an affected device to consume large amounts of memory resources, resulting in a DoS condition.
 
Safeguards
Administrators are advised to contact the vendor regarding future updates and releases.

Administrators are advised to allow only trusted users to have network access.

Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.

To mitigate denial of service attacks, apply hardware rate limiter features to limit packets that require CPU processing. See vendor documentation for specific configuration instructions. For hardware rate limiting configuration details, see Cisco Catalyst 6500 Denial of Service (DoS) Protection Configuration Guide.

Administrators are advised to monitor affected systems.
 
Patches/Software
Software updates are not available.
