Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-531: Inclusion of Sensitive Information in Test Code, where accessible test applications can pose a variety of security risks. since developers or administrators rarely consider that someone besides themselves would even know about the existence of these applications, it is common for them to contain sensitive information or functions. In Pear/http request2, 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

In PEAR HTTP_Request2 before 2.7.0, multiple files in the tests directory, notably tests/_network/getparameters.php and tests/_network/postparameters.php, reflect any GET or POST parameters, leading to XSS.
