Smarty is a template library responsible for composing web-page output in CiviCRM. If Smarty encounters an internal processing error (such as an unknown template-file or unknown template-function), then it outputs an error message. In Smarty 2.6.26 and earlier, the error message is not properly escaped and (in combination with other, unidentified flaws) may provide a vector for a cross-site scripting attack. The issue is resolved in Smarty 2.6.27 and CiviCRM 4.3.4.

The "Quick Search" bar in CiviCRM v4.3 includes a backend for processing search requests which is split in two layers. Both layers may be accessed remotely by backend users with permission "access CiviCRM." A malicious user may bypass one layer (which performs SQL validation/escaping) and call the second layer directly (thus bypassing SQL validation/escaping).

Note: The scope of the SQL injection is limited compared to a typical SQL injection because CiviCRM's SQL API does not accept SQL queries with multiple statements. Consequently:

CiviCRM v2+ includes a "Custom Search" system which allows administrators to register customized search forms and includes some default custom-searches (e.g. "Find Contribution Amounts by Tag"). CiviCRM also supports role-based access controls using permissions like "access CiviContribute" or "access CiviEvent". For the default custom-searches, CiviCRM does not enforce the expected role-based access controls.

OpenFlashChart is a library used to render dashboards and reports in CiviCRM v3+. The library includes a program written for Adobe Flash which accepts data via query string. The data is not properly sanitisized. If an attacker provides an authorized user with a maliciously constructed link, the attacker can cause the user to execute arbitrary JavaScript code.

Note: This document is being published in June 2013 to conform with our new disclosure format. However, the issue was previously disclosed in detail in a civicrm.org blog-post (April 2013) and in summary in a civicrm.org release-announcement (Nov 2012).
