Impact
By exploiting the XSS vulnerabilities, malicious actors can perform harmful actions in the user's web browser in the session context of the affected user. Some examples of this include, but are not limited to: Obtaining user session tokens. Performing administrative actions (when an administrative user is affected). These vulnerabilities pose a high security risk. Since a sensitive cookie is not configured with the HttpOnly attribute and administrator JWTs are stored in sessionStorage, any successful XSS attack could enable the theft of session cookies and administrative tokens.
Description
A request parameter from the URL of the login page is directly rendered within the Twig template of the Storefront login page without further processing or input validation. This allows direct code injection into the template via the URL parameter. An attacker can create malicious links that could be used in a phishing attack. The parameter waitTime lacks proper input validation.
The attack can be tested with the following URL pattern:
/account/login?loginError=1&waitTime=<a%20href%3D"https%3A%2F%2Fde.wikipedia.org%2Fwiki%2FPhishing">Here<%2Fa>
The same applies to the errorSnippet parameter:
/account/login?loginError=1&errorSnippet=Reset%20your%20password%20%3Ca%20href%3D%22https%3A%2F%2Fde.wikipedia.org%2Fwiki%2FPhishing%22%3Ehere%3C%2Fa%3E.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. The attacker needs the user to perform some action, like clicking a link. The impact is confined to the system where the vulnerability exists. There is a low impact on the confidentiality of the information. There is a high impact on the integrity of the data.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
