Description

Overview

The "Bytebase" application does not restrict low privilege user from accessing admin projects

Details

The "Bytebase" application does not restrict low privilege user from accessing admin projects for which an unauthorized user can view the "projects" created by "Admin". The affected endpoint is /api/project?user=${userId}.

PoC

  1. Log in to the application as both "Admin" ([email protected]:admin) and Developer "User" ([email protected]:user) and then click on "Projects".
  2. Now open "Burp suite" and turn "Intercept on" and from "admin" dashboard click on "projects" and see the "user id" of "admin" in the capture request.
  3. Note the "user id" and "Forward" the request and again capture the request of "projects" from the "user" dashboard and change "user id" to "admin user id" and "Forward" the request.
  4. Now "user" can see the "projects" created by "admin".

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.
