Affected Versions

All versions of the Order Manager plugin are affected.

Description

This update addresses one security concern:

1. An XSS flaw that affects the order system under certain circumstances.

Resolution

If running 4.10.0, apply the patch for 4.10.1. If running a version earlier than 4.10.0, upgrade to the full 4.10.1 release. See below for mitigation for older supported releases.

Mitigation

It is best to upgrade to 4.10.1, however, if you are running a supported version of Blesta (version 4.6, 4.7, 4.8, or 4.9) you may overwrite the following files from the 4.10.1 patch:

• /blesta/plugins/order/views/templates/ajax/config.pdt
• /blesta/plugins/order/views/templates/standard/config.pdt
• /blesta/plugins/order/views/templates/wizard/config.pdt

Security Advisory

We have released new updates for all supported versions of Blesta. These updates address security related concerns with Blesta and have an impact rating of Low. More information about how we rate vulnerabilities can be found on our Security Advisories page.

Affected Versions

Versions 3.0.0 through 3.6.1 are affected.

Description

This update addresses two security concerns:

1. An undemonstrated potential vulnerability. In cooperation with a competing software application, we will release further details about this issue and how it affects Blesta once a sufficient amount of time has passed.
2. Full Path Disclosure.

Resolution

If you are running 3.6.0 or 3.6.1, apply the following patch:

3.6.x -> 3.6.2 - Download Patch

If you are running a version prior to 3.6.0, upgrade to 3.6.2:

3.6.2 - Download Full

Be sure to run ~/admin/upgrade in your browser after updating the files. A new configuration variable will be written to your ~/config/blesta.php config file. Ensure that it is writable.

Related tasks: CORE-2228, CORE-2231

Mitigation

It is best to upgrade to 3.6.2, however, the Full Path Disclosure issue may be mitigated by changing the System.debug variable to false in ~/config/core.php. To do so, open ~/config/core.php and look for the following:

<?php
...
Configure::set("System.debug", true);

Change this to:

<?php
...
Configure::set("System.debug", false);

This will effectively disable stack traces within minPHP “Oh noes” error pages. When upgrading to Blesta 3.6.2, this option is defined and overridden in Blesta’s config file (~/config/blesta.php).

An authenticated staff member may be able to affect settings in the system where they are otherwise prohibited via ACL restrictions, via carefully crafted HTTP POST requests under limited circumstances. This issue is classified as a Moderate vulnerability. (CORE-1163)

Affected Versions

Versions 3.0.0 through 3.0.9, and 3.1.0 through 3.1.1 are affected.

Description

Active and valid staff members may be able to access areas of the application without proper ACL permissions. Additionally, staff members may not be logged out immediately after being made inactive. These issues are classified as Moderate vulnerabilities. Patch release 3.0.10 and 3.1.2 correct these vulnerabilities.

Resolution

If you are running 3.0.x upgrade to version 3.0.10. If you are running 3.1.x upgrade to version 3.1.2.

Security Advisory - Staff Permission Escalation

Affected Versions

Versions 3.0.0 through 3.0.8, and 3.1.0 are affected.

Description

Active and valid staff members may be able to gain additional permissions through crafted URLs. Because this issue requires that the user have an active and valid staff member account, this is classified as a Moderate vulnerability. Patch release 3.0.9 and 3.1.1 corrects this vulnerability.

Resolution

If you are running 3.0.x upgrade to version 3.0.9. If you are running 3.1.0 upgrade to version 3.1.1.
