Overview<\/strong><\/p>\n

A critical vulnerability has been discovered in OpenMediaVault 7.4.17, potentially allowing attackers to escalate privileges to root level. This report provides a comprehensive analysis of CVE-2025-50674, detailing the potential threat it poses to data security and system integrity.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-50674
\nSeverity: High (7.8 CVSS Score)
\nAttack Vector: Local
\nPrivileges Required: User
\nUser Interaction: Required
\nImpact: Privilege escalation<\/a> to root, potentially resulting in system compromise or data leakage.<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

OpenMediaVault | 7.4.17<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability resides in the changePassword method in the \/usr\/share\/php\/openmediavault\/system\/user.inc file<\/a>. A local authenticated attacker can exploit this vulnerability to escalate their privileges<\/a> to root level, potentially allowing them to compromise the system or leak data.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

While no specific code is provided for this vulnerability<\/a>, the conceptual exploitation could involve an authenticated user changing their password in a manner that manipulates the system and escalate their privileges. It could look something like this:<\/p>\n

changePassword($user, $current_password, $new_password, $root_privileges = true);<\/code><\/pre>\n
In this conceptual example, the attacker modifies the changePassword function to include a parameter that grants root privileges<\/a>.<\/p>\n
Remediation<\/strong><\/p>\n
As a mitigation measure, it is strongly advised to apply vendor-provided patches immediately. In case of patch unavailability, users are advised to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation. Regularly updating and patching systems can significantly reduce the risk of such vulnerabilities<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
