Package

glpi (glpi)

Affected versions

>= 0.83

Patched versions

9.5.13, 10.0.7

Description

Impact

An authenticated user can modify emails of any user, and can therefore takeover another user account through the "forgotten password" feature. By modifiying emails, the user can also receive sensitive data through GLPI notifications.

Workarounds

Account takeover can be prevented by deactivating all notifications related to Forgotten password? event. However, it will not prevent unauthorized modification of any user emails.

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.
