CVE-2019-11016: Open Redirect Vulnerability
Earlier this year the Qualys Web Application Scanning team discovered and reported an open redirect vulnerability (CVE-2019-11016) in Elgg, an open source rapid development framework for socially aware web applications, which the Elgg team promptly fixed.
Versions of the Elgg framework before 1.12.18 and 2.3.x versions before 2.3.11 are vulnerable to open redirect via the $url parameter. An attacker could abuse the functionality by entering a particular path that triggers an open redirect to an attacker-controlled website.
Because this type of vulnerability is not uncommon, QID 150051 in Qualys Web Application Scanning (WAS) was improved to report if this type of open redirect vulnerability is found in a scanned web application.
