An attacker may exploit this vulnerability by submitting a crafted URL into the Section Header field.

To exploit this vulnerability, an attacker needs to submit a crafted URL into the Section Header field in order to trick the WBCE CMS v1.5.4 into executing a web script or HTML code.

Assuming that the user has posted a link in the Section Header field and the user does not have the CAPTCHA enabled, the WBCE CMS v1.5.4 will attempt to validate the posted link by retrieving the posted link and attempting to validate the link via the Google search engine.

If the user has the CAPTCHA enabled, the WBCE CMS v1.5.4 will not attempt to validate the posted link and it will instead redirect the user to the login screen.

If the user does not have the CAPTCHA enabled, the WBCE CMS v1.5.4 will attempt to validate the posted link and it will simply redirect the user to the login screen.

The WBCE CMS v1.5.4 does not validate the posted link and it does not perform any additional validation on the posted link before redirecting the user to the login page.

Therefore, an attacker may leverage this vulnerability to craft a URL that is invalid and inject the invalid URL into the Section Header field of the WBCE CMS v1.5.4 and receive a valid URL that does not require any

How do I know if my website is vulnerable?

If you are using the WBCE CMS v1.5.4 and you have CAPTCHA enabled, you will not be vulnerable to this vulnerability.
