Description

Wowza Streaming Engine through 4.8.11+5 could allow an authenticated, remote attacker to exhaust filesystem resources via the /enginemanager/server/vhost/historical.jsdata vhost parameter. This is due to the insufficient management of available filesystem resources. An attacker could exploit this vulnerability through the Virtual Host Monitoring section by requesting random virtual-host historical data and exhausting available filesystem resources. A successful exploit could allow the attacker to cause database errors and cause the device to become unresponsive to web-based management. (Manual intervention is required to free filesystem resources and return the application to an operational state.)

Public exploits

Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.

Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
