Vulnerability details

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists to error within the send file code for the NIO HTTP connector, which causes current Processor object being added to the Processor cache multiple times. This behavior means that sharing the same Processor for concurrent requests can lead to leakage of potentially sensitive information between requests, such as session ID, request body, etc.

Successful exploitation of the vulnerability may allow an attacker to obtain potentially sensitive information.
