Patched versions

1.7.10

Description

Impact

Before version 1.7.10, an attacker is able to make arbitrary changes to many components including issues, comments, files, users, and groups via a CSRF attack. This includes all administrative actions if the targeted user is an administrator.

Patches

Phproject 1.7.10 includes new CSRF protection on all web-based POST requests that prevents this type of attack.

Workarounds

None. This update should be non-breaking for typical use, so it is strongly recommended to install the 1.7.10 update to fix the issue.

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.
