info:
|
|
name: XStream <1.4.17 - Remote Code Execution
|
|
author: pwnhxl
|
|
severity: high
|
|
description: |
|
|
XStream before 1.4.17 is susceptible to remote code execution. An attacker can execute commands of the host by manipulating the processed input stream, thereby making it possible to obtain sensitive information, modify data, and/or execute unauthorized administrative operations in the context of the affected site.
|
|
remediation: Patched in 1.4.17.
