How the Exploit Works
The vulnerability resides in the changePassword method in the /usr/share/php/openmediavault/system/user.inc file. A local authenticated attacker can exploit this vulnerability to escalate their privileges to root level, potentially allowing them to compromise the system or leak data.
Conceptual Example Code
While no specific code is provided for this vulnerability, 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:
changePassword($user, $current_password, $new_password, $root_privileges = true);In this conceptual example, the attacker modifies the changePassword function to include a parameter that grants root privileges.
Remediation
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.
