SugarCRM Security

SugarCRM is one of the most popular customer relationship management solutions. It is available as a commercial edition and as an open-source community edition and is used by more than 2 million individuals in over 120 countries to manage sensitive customer data 1. Lately its security attracted attention after a researcher reported multiple security issues in the code 2. As a result, a new version of SugarCRM was released.

We wanted to check what our automated code analysis technology RIPS would find after the recent manual audit and how it could contribute to the security. As a result, critical issues were uncovered that could allow attackers to steal customer data or sensitive files from the server.

Roundcube

Roundcube is a widely distributed open-source webmail software used by many organizations and companies around the globe. The mirror on SourceForge, for example, counts more than 260,000 downloads in the last 12 months1 which is only a small fraction of the actual users. Once Roundcube is installed on a server, it provides a web interface for authenticated users to send and receive emails with their web browser.

In this post, we show how a malicious user can remotely execute arbitrary commands on the underlying operating system, simply by writing an email in Roundcube 1.2.2 (>= 1.0). This vulnerability is highly critical because all default installations are affected. We urge all administrators to update the Roundcube installation to the latest version 1.2.3 as soon as possible.
