Description

Summary

A vulnerability has been discovered in the handling of the referrer header in the application, which could allow an attacker to conduct open redirects. The issue arises from improper validation of the referrer header in certain conditions. By manipulating the referrer header, an attacker could potentially redirect users to malicious websites, phishing pages, or other dangerous destinations.

PoC

If you change the referer header, you will be redirected to that domain without verifying.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
