Description
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in the "/plugins/servlet/gadgets/makeRequest" resource. A remote attacker can send a specially crafted HTTP request, gain access to the content of internal network resources due to a logic bug in the "JiraWhitelist" class and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
