Advisory Details: |
High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in eShop for Wordpress which could be exploited to perform cross-site scripting attacks.
1) Cross-site scripting (XSS) vulnerabilities in eShop for Wordpress
1.1 The vulnerability exists due to input sanitation error in the "eshoptemplate" parameter in wp-admin/admin.php (when "page" is set to "eshop-templates.php"). A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website. Successful exploitation requires that victim is logged-in into the application and has access to administrative interface.
Exploitation example:
http://[host]/wp-admin/admin.php?page=eshop-templates.php&eshoptemplate=%22% 3E%3Cscript%3Ealert%28document.cookie%29;%3C/script%3E
1.2 The vulnerability exists due to input sanitation error in the "action" parameter in wp-admin/admin.php (when "page" is set to "eshop-orders.php"). A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website. Successful exploitation requires that victim is logged-in into the application and has access to administrative interface.
Exploitation example:
http://[host]/wp-admin/admin.php?page=eshop-orders.php&view=1&action=%22%3E% 3Cscript%3Ealert%28document.cookie%29;%3C/script%3E
1.3 The vulnerability exists due to input sanitation error in the "viewemail" parameter in wp-admin/admin.php (when "page" is set to "eshop-orders.php"). A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website. Successful exploitation requires that victim is logged-in into the application and has access to administrative interface.
Exploitation example:
http://[host]/wp-admin/admin.php?page=eshop-orders.php&viewemail=%22%3E%3Csc ript%3Ealert%28document.cookie%29;%3C/script%3E
