Denial Of Service (DoS)

github.com/cubefs/cubefs is vulnerable to Denial Of Service (DoS). The vulnerability is due to improper handling of incoming HTTP requests in a CubeFS HandlerNode that could allow an authenticated users to send maliciously-crafted requests that would crash the ObjectNode. An attacker can send a malicious request that could make the ObjectNode allocate more memory than the available amount leading to memory exhaustion by sending a single malicious request. The precondition for this attack to be successful is an attacker must be authenticated and have permissions to delete objects. In addition, the attacker would need to know the names of existing buckets of the CubeFS deployment , otherwise the request would be rejected before it reaches the vulnerable code.
