info:
|
|
name: XStream <1.4.18 - Server-Side Request Forgery
|
|
author: pwnhxl
|
|
severity: high
|
|
description: |
|
|
XStream before 1.4.18 is susceptible to server-side request forgery. An attacker can request data from internal resources that are not publicly available by manipulating the processed input stream with a Java runtime version 14 to 8. This makes it possible to obtain sensitive information, modify data, and/or execute unauthorized administrative operations in the context of the affected site.
|
|
remediation: |
|
|
Upgrade XStream to version 1.4.18 or later to mitigate the vulnerability.
