Description

Summary

the vulnerability is that users (such as resellers or customers) are able to create accounts with the same email address as an existing account (e.g., if the admin has [email protected], others can also create an account using the same email). This creates potential issues with account identification and security.

Impact

Local/Authenticated: This vulnerability can be exploited by authenticated users (e.g., reseller, customer) who can create accounts with the same email address that has already been used by another account, such as the admin.
Email-based: The attack vector is email-based, as the system does not prevent multiple accounts from registering the same email address, leading to possible conflicts and security issues.

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.
