Low risk information disclosure in Sourcegraph

Low
andreeleuterio published GHSA-mq5p-477h-xgwv Aug 2, 2021

Package

No package listed

Affected versions

< 3.30.0

Patched versions

3.30.0

Description

Impact

Sourcegraph before version 3.30.0 has two potential information leaks. The site-admin area can be accessed by regular users and all information and features are properly protected except for:

  • Daily Usage statistics
  • Code intelligence uploads and indexes

It is not possible to alter the information, nor interact with any other features in the site-admin area.

Patches

The issue is patched in version 3.30.0 where the information cannot be accessed by unprivileged users. We may work on further defenses as defense-in-depth.

Workarounds

There are no workarounds and we recommend upgrading to the latest release.

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.
