CVE-2024-9050 - NetworkManager-libreswan Privilege Escalation Vulnerability

CVE ID : CVE-2024-9050
Published : Oct. 22, 2024, 1:15 p.m. | 35 minutes ago
Description : A flaw was found in the libreswan client plugin for NetworkManager (NetkworkManager-libreswan), where it fails to properly sanitize the VPN configuration from the local unprivileged user. In this configuration, composed by a key-value format, the plugin fails to escape special characters, leading the application to interpret values as keys. One of the most critical parameters that could be abused by a malicious user is the `leftupdown`key. This key takes an executable command as a value and is used to specify what executes as a callback in NetworkManager-libreswan to retrieve configuration settings back to NetworkManager. As NetworkManager uses Polkit to allow an unprivileged user to control the system's network configuration, a malicious actor could achieve local privilege escalation and potential code execution as root in the targeted machine.
Severity: 7.8 | HIGH
