CVE-2025-49113
Overview
This vulnerability is a PHP Object Deserialization flaw occurring in Roundcube Webmail's file upload handling component. The root cause is improper validation of the _from parameter in the URL processed by program/actions/settings/upload.php, which allows crafted serialized objects to be deserialized unsafely. The affected feature is the authenticated user settings upload functionality, where user-supplied input is deserialized without sufficient integrity checks.
Vulnerability Description
Roundcube Webmail before 1.5.10 and 1.6.x before 1.6.11 allows remote code execution by authenticated users because the _from parameter in a URL is not validated in program/actions/settings/upload.php, leading to PHP Object Deserialization.
Impact
An attacker with valid authentication can execute arbitrary PHP code on the server, resulting in full system compromise. This includes the ability to execute shell commands, manipulate server files, and potentially pivot within the network. The prerequisite is possession of valid user credentials, which could be low-privileged accounts. The real-world consequence is a complete breach of the mail server environment, risking data exfiltration, service disruption, and lateral movement within the infrastructure.
Solution
Upgrade Roundcube Webmail to version 1.5.10 or later in the 1.5.x branch, or 1.6.11 or later in the 1.6.x branch as specified in the official Roundcube security advisory (https://roundcube.net/news/2025/06/01/security-updates-1.6.11-and-1.5.10). Follow the vendor's release notes and patch instructions available on their GitHub repository (https://github.com/roundcube/roundcubemail/releases/tag/1.6.11) to ensure the vulnerability is fully mitigated.
