Description
This security bulletin contains information about 2 vulnerabilities.
1) Insufficient verification of data authenticity (CVE-ID: CVE-2020-36327)
CWE-ID: CWE-345 - Insufficient Verification of Data Authenticity
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to insufficient verification of data authenticity in Bundler, when choosing a dependency source. The application selects a dependency source based on the highest gem version number, which means that a rogue gem found at a public source may be chosen, even if the intended choice was a private gem that is a dependency of another private gem that is explicitly depended on by the application.
2) Improper Neutralization of Argument Delimiters in a Command (CVE-ID: CVE-2021-43809)
CWE-ID: CWE-88 - Argument Injection or Modification
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to execute arbitrary code on the target system.
The vulnerability occurs when working with untrusted and apparently harmless `Gemfile`'s. A local user can trick the victim into opening a specially crafted directory containing a `Gemfile` file that declares a dependency that is located in a Git repository and execute arbitrary code on the target system.
