A vulnerability in system resource management in the Cisco Videoscape Session Resource Manager (VSRM) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition because the device unexpectedly restarts.
The vulnerability occurs because the VSRM is not installed using best practices and in a secure environment where DoS attacks are prevented before reaching the adjacent network. An attacker could exploit this vulnerability only by being on the adjacent network and directing a flood of traffic at the devices upstream to the VSRM. An exploit could allow the attacker to cause a DoS condition. The VSRM resumes normal operation when the attack ceases on the upstream devices.
