October System module has an Open Redirect for Administrator Accounts

Low severity GitHub Reviewed Published Jun 25, 2024 in octobercms/october

Package

composer october/system (Composer)

Affected versions

>= 3.2, < 3.5.15

Patched versions

3.5.15

Description

Impact

This advisory affects authenticated administrators who may be redirected to an untrusted URL using the PageFinder schema. The resolver for the page finder link schema (october://) allowed external links, therefore allowing an open redirect outside the scope of the active host.

This vulnerability assumes a trusted user will attack another trusted user and cannot be actively exploited without access to the administration panel and interaction from the other user.

Patches

This issue has been patched in v3.5.15.

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.
