Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Phpxmlrpc/phpxmlrpc, 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

The bundled xml-rpc debugger is susceptible to XSS attacks. Since the debugger is not designed to be exposed to end users but only to the developers using this library, and in the default configuration it is not exposed to requests from the web, the likelihood of exploitation may be low.
