ZendFramework potential XML eXternal Entity injection vectors

Critical severity GitHub Reviewed Published Jun 7, 2024 to the GitHub Advisory Database • Updated Jun 7, 2024

Package

composer zendframework/zendframework1 (Composer)

Affected versions

>= 1.12.0, < 1.12.4

Numerous components utilizing PHP’s DOMDocument, SimpleXML, and xml_parse functionality are vulnerable to two types of attacks:

• XML eXternal Entity (XXE) Injection attacks. The above mentioned extensions are insecure by default, allowing external entities to be specified by adding a specific DOCTYPE element to XML documents and strings. By exploiting this vulnerability an application may be coerced to open arbitrary files and/or TCP connections.
• XML Entity Expansion (XEE) vectors, leading to Denial of Service vectors. XEE attacks occur when the XML DOCTYPE declaration includes XML entity definitions that contain either recursive or circular references; this leads to CPU and memory consumption, making Denial of Service exploits trivial to implement.
