Description<\/h3>\n

A reflected XSS attack (or non-persistent attack) occurs when a malicious script is reflected off of a web application to the victim\u2019s browser. The attack is typically delivered via email or a web site and activated through a link, which sends a request to a website with a vulnerability that enables execution of malicious scripts. The <\/span>main_page<\/code> parameter is vulnerable to reflected XSS in the <\/span>\/includes\/templates\/template_default\/common\/tpl_main_page.php<\/code> and the <\/span>\/includes\/templates\/responsive_classic\/common\/tpl_main_page.php<\/code> files.<\/span><\/p>\n

<\/span><\/p>\n

Proof of Concept (PoC)<\/h3>\n

It is possible to send one of the two following requests to inject HTML code into the application:<\/p>\n

[\/et_pb_text][et_pb_image src=\"https:\/\/herolab.usd.de\/wp-content\/uploads\/sites\/9\/2021\/07\/evidence-1-2.png\" _builder_version=\"4.9.4\" _module_preset=\"default\" title_text=\"evidence-1-2\" hover_enabled=\"0\" sticky_enabled=\"0\"][\/et_pb_image][et_pb_image src=\"https:\/\/herolab.usd.de\/wp-content\/uploads\/sites\/9\/2021\/07\/evidence-2-5.png\" _builder_version=\"4.9.4\" _module_preset=\"default\" title_text=\"evidence-2-5\" hover_enabled=\"0\" sticky_enabled=\"0\"][\/et_pb_image][et_pb_text _builder_version=\"4.9.4\" _module_preset=\"cc5ac6f4-ebbd-4b3f-bc92-4dfc1f15fe2c\" hover_enabled=\"0\" sticky_enabled=\"0\"]<\/p>\n

The following HTTP response shows the injected JavaScript payload that would cause an alert box to pop up.<\/span><\/p>\n

[\/et_pb_text][et_pb_image src=\"https:\/\/herolab.usd.de\/wp-content\/uploads\/sites\/9\/2021\/07\/evidence-3-1.png\" _builder_version=\"4.9.4\" _module_preset=\"default\" title_text=\"evidence-3-1\" hover_enabled=\"0\" sticky_enabled=\"0\"][\/et_pb_image][et_pb_text _builder_version=\"4.9.4\" _module_preset=\"cc5ac6f4-ebbd-4b3f-bc92-4dfc1f15fe2c\" hover_enabled=\"0\" sticky_enabled=\"0\"]<\/p>\n

\n
\n

The vulnerable code was located inside <\/span>includes\/templates\/responsive_classic\/common\/tpl_main_page.php<\/code><\/p>\n

<\/h3>\n

Fix<\/h3>\n

All user supplied input should be encoded on delivery or before rendering to prevent the injection of HTML code.<\/p>\n
