Multiple Cisco products contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service condition. Updates are not available.
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.
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.
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.
Cisco has released a security notice at the following link: CVE-2013-5488
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.
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.
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.
