CVE-2020-8167

There is a vulnerability in rails-ujs that allows attackers to send CSRF tokens to wrong domains.

Versions Affected: rails <= 6.0.3 Not affected: Applications which don't use rails-ujs. Fixed Versions: rails >= 5.2.4.3, rails >= 6.0.3.1

Impact

This is a regression of CVE-2015-1840.

In the scenario where an attacker might be able to control the href attribute of an anchor tag or the action attribute of a form tag that will trigger a POST action, the attacker can set the href or action to a cross-origin URL, and the CSRF token will be sent.

Workarounds

To work around this problem, change code that allows users to control the href attribute of an anchor tag or the action attribute of a form tag to filter the user parameters.

For example, code like this:

link_to params

to code like this:

link_to filtered_params

def filtered_params
  # Filter just the parameters that you trust
end

A CSRF vulnerability exists in rails <= 6.0.3 rails-ujs module that could allow attackers to send CSRF tokens to wrong domains.

This update for rmt-server fixes the following issues:

Update to version 2.6.5:

• Solved potential bug of SCC repository URLs changing over time. RMT now self heals by removing the previous invalid repository and creating the correct one.
• Add web server settings to /etc/rmt.conf: Now it's possible to configure the minimum and maximum threads count as well the number of web server workers to be booted through /etc/rmt.conf.
• Instead of using an MD5 of URLs for custom repository friendly_ids, RMT now builds an ID from the name.
• Fix RMT file caching based on timestamps: Previously, RMT sent GET requests with the header 'If-Modified-Since' to a repository server and if the response had a 304 (Not Modified), it would copy a file from the local cache instead of downloading. However, if the local file timestamp accidentally changed to a date newer than the one on the repository server, RMT would have an outdated file, which caused some errors. Now, RMT makes HEAD requests to the repositories servers and inspect the 'Last-Modified' header to decide whether to download a file or copy it from cache, by comparing the equalness of timestamps.
• Fixed an issue where relative paths supplied to rmt-cli import repos caused the command to fail.
• Friendlier IDs for custom repositories: In an effort to simplify the handling of SCC and custom repositories, RMT now has friendly IDs. For SCC repositories, it's the same SCC ID as before. For custom repositories, it can either be user provided or RMT generated (MD5 of the provided URL). Benefits:
  • rmt-cli mirror repositories now works for custom repositories.
  • Custom repository IDs can be the same across RMT instances.
  • No more confusing 'SCC ID' vs 'ID' in rmt-cli output. Deprecation Warnings:
  • RMT now uses a different ID for custom repositories than before. RMT still supports that old ID, but it's recommended to start using the new ID to ensure future compatibility.
• Updated rails and puma dependencies for security fixes.

This update for rmt-server fixes the following issues:

• Version 2.6.5

• Solved potential bug of SCC repository URLs changing over time. RMT now self heals by removing the previous invalid repository and creating the correct one.

• Version 2.6.4

• Add web server settings to /etc/rmt.conf: Now it's possible to configure the minimum and maximum threads count as well the number of web server workers to be booted through /etc/rmt.conf.

• Version 2.6.3

• Instead of using an MD5 of URLs for custom repository friendly_ids, RMT now builds an ID from the name.

• Version 2.6.2

• Fix RMT file caching based on timestamps: Previously, RMT sent GET requests with the header 'If-Modified-Since' to a repository server and if the response had a 304 (Not Modified), it would copy a file from the local cache instead of downloading. However, if the local file timestamp accidentally changed to a date newer than the one on the repository server, RMT would have an outdated file, which caused some errors.

• Version 2.6.1

• Fixed an issue where relative paths supplied to rmt-cli import repos caused the command to fail.

• Version 2.6.0

• Version 2.5.20

• Updated rails from 6.0.3.2 to 6.0.3.3:

  • actionview (CVE-2020-15169)

• Version 2.5.19

• RMT now has the ability to remove local systems with the command rmt-cli systems remove.

• Version 2.5.18

• Fixed exit code for rmt-cli mirror and its subcommands. Now it exits with 1 whenever an error occurs during mirroring

• Improved message logging for rtm-cli mirror. Instead of logging an error when it occurs, the command summarize all errors at the end of execution. Now log messages have colors to better identify failure/success.

• Version 2.5.17

• RMT no longer provides the installer updates repository to systems via its zypper service. This repository is used during the installation process, as it provides an up-to-date installation experience, but it has no use on an already installed system.

• Version 2.5.16

• Updated RMT's rails and puma dependencies.

  • puma (CVE-2020-11076, CVE-2020-11077, CVE-2020-5249, CVE-2020-5247 CVE-2019-16770)

  • activesupport (CVE-2020-8165)
  • railties (CVE-2019-5420)

• Version 2.5.15

• RMT now checks if repositories are fully mirrored during the activation process. Previously, RMT only checked if the repositories were enabled to be mirrored, but not that they were actually mirrored. In this case, RMTs were not able to provide the repository data which systems assumed it had.

• Version 2.5.14

• Enable 'Installer-Updates' repositories by default

• Fixed deprecation warning when thor encountered an error. Also, instead of returning 0 for thor errors, rmt-cli will return 1 instead.

• Version 2.5.13

• Added rmt-cli repos clean command to remove locally mirrored files of repositories which are not marked to be mirrored.

• Previously, RMT didn't track…
