How to Fix CVE-2019-19325

To remediate this vulnerability, upgrade all affected Silverstripe/framework dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

silverstripe/framework fixed: 4.5.2 
Upgrade silverstripe/framework to 4.5.2
silverstripe/framework fixed: 4.4.5 
Upgrade silverstripe/framework to 4.4.5
Verify Direct and Transitive Dependencies

How to Check if You Are Affected

To determine whether your application is affected by CVE-2019-19325, inspect your project dependencies for Silverstripe/framework:

inspect dependencies for silverstripe/framework

Analyze the terminal output to locate any version of Silverstripe/framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.5.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Silverstripe/framework, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

SilverStripe through 4.4.x before 4.4.5 and 4.5.x before 4.5.2 allows Reflected XSS on the login form and custom forms. Silverstripe Forms allow malicious HTML or JavaScript to be inserted through non-scalar FormField attributes, which allows performing XSS (Cross-Site Scripting) on some forms built with user input (Request data). This can lead to phishing attempts to obtain a user's credentials or other sensitive user input.
