damianhxy published GHSA-962r-m9fj-3hj9 May 21, 2023

Package

bundler Autolab (RubyGems)

Affected versions

Description

Impact

A session forgery vulnerability was discovered in Autolab's default docker installation procedure, whereby users can impersonate an administrator by manipulating their session cookie.

Patches

The vulnerability has been patched in v2.11.0. Run make update from your docker installation root directory and follow any instructions provided.

Workarounds

Define secret_key_base via the rails credentials:edit command, which will encrypt the value.

Alternatively, add the SECRET_KEY_BASE environment variable to the .env file and set it to an appropriate key value. For example:

SECRET_KEY_BASE=17c2b02fb7d21e249573a9a6fe3b1a2606653186baf53cd407f1a43f8446bda86095b9f5fa39e6c4538407253aef18e3b0ec38f4d3dedacc98e7a8c238266890

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.
