Paul

A security issue affecting Blesta versions 4.0.0 through 5.11.3 has been identified.

A path traversal vulnerability has been discovered, though the vulnerability does not allow the disclosure of Blesta configuration files. We recommend applying the appropriate patch for your release, or upgrading to version 5.11.4 as soon as possible. We give this an impact rating of High.

More information about how we rate vulnerabilities can be found on our Security Advisories page.

Always back up your files and database prior to upgrading and be sure to run /admin/upgrade in your browser after uploading either a patch or full release. Patch releases may only be applied to the minor release to which it belongs, so download the appropriate patch for your minor version. If you are running a version of Blesta between 4.0 and 5.11, upgrade to 5.11.4.

Resolution

  • If you are running version 5.11.x, apply the 5.11.4 patch above.
  • If you are running version 5.10.x, apply the 5.10.4 patch above.
  • If you are running version 4.0.x through 5.11.x, upgrade to 5.11.4 Full.

Mitigation

It is best to upgrade to 5.11.4 or apply the appropriate patch. However, if you are running an affected unsupported version of Blesta (version 4.0 through 5.9), and you need more time to upgrade, it is possible to mitigate. We are not publishing mitigation steps now due to nature of the vulnerability. For mitigation steps, open a ticket from within your account and provide your license key as well as the version of Blesta you are running along with the reason you are not able to upgrade.
