Linux Debian vulnerability analysis and mitigation
Overview
CVE-2025-49113 affects Roundcube Webmail versions before 1.5.10 and 1.6.x before 1.6.11. The vulnerability allows remote code execution by authenticated users due to improper validation of the _from parameter in program/actions/settings/upload.php, which leads to PHP Object Deserialization (NVD, Roundcube News).
Technical details
The vulnerability is classified as a PHP Object Deserialization issue (CWE-502) where the _from parameter in a URL is not properly validated in the upload.php file. The CVSS v3.1 score is 9.9 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H, indicating network accessibility, low attack complexity, and high impact across confidentiality, integrity, and availability (NVD).
Impact
