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 by creating a malicious configuration."}], "affected": [{"versions": [{"status": "affected", "version": "0", "lessThan": "1.2.24", "versionType": "semver"}],

However, this would also block them from connecting to new Wi-Fi networks, which is not ideal for laptops but might be acceptable for workstations. Server customers typically don't need to be concerned, as they generally don't have local users capable of exploiting the bug."}, "name": "CVE-2024-9050", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:10", "fix_state": "Affected", "package_name": "NetworkManager-libreswan", "product_name": "Red Hat Enterprise Linux 10"}], "public_date": "2024-10-22T12:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2024-9050\nhttps://nvd.nist.gov/vuln/detail/CVE-2024-9050\nhttps://www.openwall.com/lists/oss-security/2024/10/25/1"], "statement": "This issue marked with an Important severity due to its potential to enable local privilege escalation and arbitrary code execution. Since NetworkManager uses Polkit to allow unprivileged users to manage network configurations, the failure to properly sanitize the VPN configuration, particularly the `leftupdown` key, creates a direct attack vector. By leveraging this vulnerability, an attacker can inject malicious commands into the VPN configuration, bypassing user privilege boundaries and gaining root access.", "threat_severity": "Important"}
