This Security Advisory is about a vulnerability in the way eZ Platform and eZ Publish Legacy handles file uploads, which can in the worst case lead to remote code execution (RCE), a very serious threat. An attacker would need access to uploading files to be able to exploit the vulnerability, so if you have strict controls on this and trust all who have this permission, you're not affected. On the …
This security advisory fixes 4 separate vulnerabilities in eZ Publish Legacy, and we recommend that you install it as soon as possible if you are using Legacy by itself or via the LegacyBridge. First, it increases the randomness, and thus the security, of the pseudo-random bytes used to generate a hash for the "forgot password" feature.

This Security Advisory is about a vulnerability in the Legacy shop module. A backend editor could perform object injection in discount rules. This would require backend access and permission to edit discount rules. While object injection in itself is a serious vulnerability, the permission requirement means that normally only administrators would be able to exploit it, that's why it was classified as Medium severity.
The eZ Platform and Legacy are affected by an issue related to how uploaded PHP and PHAR files are handled, and consists of two parts: 1. Web server configuration, and 2. Disabling the PHAR stream wrapper. 1. WEB SERVER CONFIGURATION The sample web server configuration in our documentation can in some cases allow the execution of uploaded PHP/PHAR code. This can be abused to allow priviledge escalation and breach of …
