| CVE-2022-29176 | 1 Rubygems | 1 Rubygems.org | 2023-02-10 | 6.0 MEDIUM | 7.5 HIGH |
| Rubygems is a package registry used to supply software for the Ruby language ecosystem. Due to a bug in the yank action, it was possible for any RubyGems.org user to remove and replace certain gems even if that user was not authorized to do so. To be vulnerable, a gem needed: one or more dashes in its name creation within 30 days OR no updates for over 100 days At present, we believe this vulnerability has not been exploited. RubyGems.org sends an email to all gem owners when a gem version is published or yanked. We have not received any support emails from gem owners indicating that their gem has been yanked without authorization. An audit of gem changes for the last 18 months did not find any examples of this vulnerability being used in a malicious way. A deeper audit for any possible use of this exploit is ongoing, and we will update this advisory once it is complete. Using Bundler in --frozen or --deployment mode in CI and during deploys, as the Bundler team has always recommended, will guarantee that your application does not silently switch to versions created using this exploit. To audit your application history for possible past exploits, review your Gemfile.lock and look for gems whose platform changed when the version number did not change. For example, gemname-3.1.2 updating to gemname-3.1.2-java could indicate a possible abuse of this vulnerability. RubyGems.org has been patched and is no longer vulnerable to this issue as of the 5th of May 2022. | |||||
| CVE-2022-29218 | 1 Rubygems | 1 Rubygems.org | 2022-12-02 | 5.0 MEDIUM | 7.5 HIGH |
| RubyGems is a package registry used to supply software for the Ruby language ecosystem. An ordering mistake in the code that accepts gem uploads allowed some gems (with platforms ending in numbers, like `arm64-darwin-21`) to be temporarily replaced in the CDN cache by a malicious package. The bug has been patched, and is believed to have never been exploited, based on an extensive review of logs and existing gems by rubygems. The easiest way to ensure that an application has not been exploited by this vulnerability is to verify all downloaded .gems checksums match the checksum recorded in the RubyGems.org database. RubyGems.org has been patched and is no longer vulnerable to this issue. | |||||
| CVE-2022-36073 | 1 Rubygems | 1 Rubygems | 2022-09-12 | N/A | 8.8 HIGH |
| RubyGems.org is the Ruby community gem host. A bug in password & email change confirmation code allowed an attacker to change their RubyGems.org account's email to an unowned email address. Having access to an account whose email has been changed could enable an attacker to save API keys for that account, and when a legitimate user attempts to create an account with their email (and has to reset password to gain access) and is granted access to other gems, the attacker would then be able to publish and yank versions of those gems. Commit number 90c9e6aac2d91518b479c51d48275c57de492d4d contains a patch for this issue. | |||||
| CVE-2018-1000073 | 1 Rubygems | 1 Rubygems | 2020-08-24 | 5.0 MEDIUM | 7.5 HIGH |
| RubyGems version Ruby 2.2 series: 2.2.9 and earlier, Ruby 2.3 series: 2.3.6 and earlier, Ruby 2.4 series: 2.4.3 and earlier, Ruby 2.5 series: 2.5.0 and earlier, prior to trunk revision 62422 contains a Directory Traversal vulnerability in install_location function of package.rb that can result in path traversal when writing to a symlinked basedir outside of the root. This vulnerability appears to have been fixed in 2.7.6. | |||||
| CVE-2019-8324 | 4 Debian, Opensuse, Redhat and 1 more | 4 Debian Linux, Leap, Enterprise Linux and 1 more | 2020-08-24 | 6.8 MEDIUM | 8.8 HIGH |
| An issue was discovered in RubyGems 2.6 and later through 3.0.2. A crafted gem with a multi-line name is not handled correctly. Therefore, an attacker could inject arbitrary code to the stub line of gemspec, which is eval-ed by code in ensure_loadable_spec during the preinstall check. | |||||
| CVE-2019-8325 | 3 Debian, Opensuse, Rubygems | 3 Debian Linux, Leap, Rubygems | 2020-08-19 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in RubyGems 2.6 and later through 3.0.2. Since Gem::CommandManager#run calls alert_error without escaping, escape sequence injection is possible. (There are many ways to cause an error.) | |||||
| CVE-2019-8323 | 3 Debian, Opensuse, Rubygems | 3 Debian Linux, Leap, Rubygems | 2020-08-19 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in RubyGems 2.6 and later through 3.0.2. Gem::GemcutterUtilities#with_response may output the API response to stdout as it is. Therefore, if the API side modifies the response, escape sequence injection may occur. | |||||
| CVE-2019-8322 | 3 Debian, Opensuse, Rubygems | 3 Debian Linux, Leap, Rubygems | 2020-08-19 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in RubyGems 2.6 and later through 3.0.2. The gem owner command outputs the contents of the API response directly to stdout. Therefore, if the response is crafted, escape sequence injection may occur. | |||||
| CVE-2019-8321 | 3 Debian, Opensuse, Rubygems | 3 Debian Linux, Leap, Rubygems | 2020-08-19 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in RubyGems 2.6 and later through 3.0.2. Since Gem::UserInteraction#verbose calls say without escaping, escape sequence injection is possible. | |||||
| CVE-2019-8320 | 1 Rubygems | 1 Rubygems | 2020-08-16 | 8.8 HIGH | 7.4 HIGH |
| A Directory Traversal issue was discovered in RubyGems 2.7.6 and later through 3.0.2. Before making new directories or touching files (which now include path-checking code for symlinks), it would delete the target destination. If that destination was hidden behind a symlink, a malicious gem could delete arbitrary files on the user's machine, presuming the attacker could guess at paths. Given how frequently gem is run as sudo, and how predictable paths are on modern systems (/tmp, /usr, etc.), this could likely lead to data loss or an unusable system. | |||||
