Account takeover through password reset poisoning

Moderate
samuelwei published GHSA-mc6f-fj9h-5735 Nov 8, 2023

Package

docker pilos/pilos (Docker)

Affected versions

>= 2.0, < 2.3

Patched versions

2.3

Description

Impact

The password reset component deployed within PILOS uses the hostname supplied within the request host header when building a password reset URL. It may be possible to manipulate the URL sent to PILOS users when so that it points to the attackers server thereby disclosing the password reset token if/when the link is followed.

This only affects local user accounts and requires the password reset option to be enabled.

Patches

Users should update to v2.3

Workarounds

Set an explict Host and X-Forwarded-Host header in the reverse proxy.

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.
