Access control bypass in beego

Critical severity GitHub Reviewed Published May 22, 2022 to the GitHub Advisory Database • Updated Aug 29, 2023

Package

gomod github.com/beego/beego (Go)

Affected versions

< 1.12.9

Patched versions

1.12.9

< 2.0.3
2.0.3

Description

The route lookup process in beego prior to 1.12.9 and 2.x prior to 2.0.3 allows attackers to bypass access control. When a /p1/p2/:name route is configured, attackers can access it by appending .xml in various places (e.g., p1.xml instead of p1).

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.
