Radu Cotescu commented on SLING-10852:
--------------------------------------
This does not apply to the way we use {{esapi}} in the Apache Sling XSS
Protection API bundle, but I have no issues to update the dependency to make
any potential static scanners happier.
> Upgrade OWASP and ESAPI Java libraries to 2.2.3.0 for vulnerability XML
> External Entity (XXE) Injection

> Key: SLING-10852
> URL: https://issues.apache.org/jira/browse/SLING-10852
> Project: Sling
> Issue Type: Improvement
> Components: XSS Protection API
> Reporter: Arun Kumar Ram
> Assignee: Radu Cotescu
> Priority: Major
> Fix For: XSS Protection API 2.2.16

> The {{esapi}} package is vulnerable to XML External Entity (XXE) attacks. The
> {{loadPropertiesFromFile()}} method in the {{XmlEsapiPropertyLoader}} class
> allows external entities to be defined in user-controlled XML input files
> that can be used to configured the application. A remote attacker with
> control over the input file used to configure the application may craft a
> malicious XML file that could lead to Denial of Service (DoS), and in certain
> circumstances Remote Code Execution (RCE)
