CVE-2017-12293
HighSummary
A vulnerability in Cisco WebEx Meetings Server could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to insufficient limitations on the number of connections that can be made to the affected software.
Risk Assessment
An attacker could exploit this vulnerability by opening multiple connections to the server and exhausting server resources, leading to a reload of the server and resulting in a DoS condition.
Recommendation
It is recommended to implement connection limits and monitor server activity to detect and prevent potential DoS attacks.
