Synopsis

Joomla! 3.3.x < 3.7.3 Multiple Vulnerabilities

Description

According to its self-reported version number, the detected Joomla! application is affected by multiple vulnerabilities :

 - A cross-site scripting (XSS) vulnerability exists due to improper validation of user-supplied input with multibyte characters. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. Note that this vulnerability affects versions 1.5.0 through 3.6.5. (CVE-2017-7985)

 - An information disclosure vulnerability exists due to improper handling of cache invalidation. An unauthenticated, remote attacker can exploit this to disclose sensitive form content. (CVE-2017-9933)

 - A cross-site scripting (XSS) vulnerability exists due to improper validation of user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-9934)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update to Joomla! version 3.7.3 or latest.
