mautic/core

source listed
  • ECOSYSTEM: introduced 0; fixed 3.3.2

### Impact Symfony parameters (which is what Mautic transforms configuration parameters into) can be used within other Symfony parameters by design. However, this also means that an admin who is normally not privy to certain parameters, such as database credentials, could expose them by leveraging any of the free text fields in Mautic’s configuration that are used in publicly facing parts of the application. For example, 1. Go to Configuration page -> Landing Page Settings -> Analytics script and enter this: console.log("db password is: %mautic.db_password%"); ` 2. Visit any landing page and open the JS dev console. You will see the following message with real instance db password: `db password is: ` Risk rating: ModerateCVSS:3.1/AV:L/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:L ### Patches Upgrade to 3.3.2 ### Workarounds No ### References No ### For more information If you have any questions or comments about this advisory: * Email us at security@mautic.org

03 / Response

What to do next

  1. vendor patch

    The original advisory lists fixed boundaries 3.3.2 for mautic/core. Confirm the publisher’s latest guidance.

    Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV

  2. investigate

    Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.

    Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. FIRST EPSS

A fixed release is not deployment evidence.

Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.

04 / Limits

What this report cannot establish
