Octokit gem published with world-writable files

Low severity GitHub Reviewed Published Jun 15, 2022 in octokit/octokit.rb • Updated Jan 27, 2023

Package

bundler octokit (RubyGems)

Affected versions

>= 4.23.0, < 4.25.0

Patched versions

4.25.0

Description

Impact

Versions 4.23.0 and 4.24.0 of the octokit gem were published containing world-writeable files.

Specifically, the gem was packed with files having their permissions set to -rw-rw-rw- (i.e. 0666) instead of rw-r--r-- (i.e. 0644). This means everyone who is not the owner (Group and Public) with access to the instance where this release had been installed could modify the world-writable files from this gem.

Malicious code already present and running on your machine, separate from this package, could modify the gem’s files and change its behavior during runtime.

Patches

Workarounds

Users can use the previous version of the gem v4.22.0. Alternatively, users can modify the file permissions manually until they are able to upgrade to the latest version.

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.
