CWE-ID: CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')

Exploit availability: Yes

Description

The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the target system.

The weakness exists due to improper neutralization of special elements. A remote attacker can supply specially crafted request parameters against Spring Data REST backed HTTP resources or use Spring Data's projection-based request payload binding hat and execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.
