high Nessus Network Monitor Plugin ID 700070
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote web server is running a PHP application that is vulnerable to multiple vulnerabilities.


Versions of MyBB (MyBulletinBoard) prior to 1.8.11 are affected by the following vulnerabilities :

- The file 'usercp.php' contains an error that can allow server side request forgery (SSRF) via specially-crafted requests. (CVE-2017-7566)
- An unspecified user-input error can allow cross-site scripting attacks (XSS). (CVE-2017-8103)
- The file 'upload/admin/modules/config/smilies.php' contains a user-input validation error that can allow file disclosure via path traversal. (CVE-2017-8104)


Upgrade to MyBB version 1.8.11 or later.
