CVSS v3.1
Official Description
Macromedia Breeze Communication Server and Breeze Live Server does 5.1 and earlier not sufficiently validate certain RTMP data, which allows attackers to cause a denial of service (instability or crash), as demonstrated using an alpha release build of Flash Player 8.5 (build 133).
Technical Analysis
CVE-2005-3900 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
