silverstripe/framework vulnerable to member disclosure in login form

Moderate severity GitHub Reviewed Published May 27, 2024 to the GitHub Advisory Database

Package

composer silverstripe/framework (Composer)

Affected versions

Description

There is a user ID enumeration vulnerability in our brute force error messages.

  • Users that don't exist in will never get a locked out message
  • Users that do exist, will get a locked out message

This means an attacker can infer or confirm user details that exist in the member table.

This issue has been resolved by ensuring that login attempt logging and lockout process works equivalently for non-existent users as it does for existant users.

This is a regression of SS-2017-002.

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.
