A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v1.0 for Windows could allow an authenticated, local attacker to run arbitrary code with elevated privileges. The PIA client is vulnerable to a DLL injection vulnerability during the software update process. The updater loads several libraries from a folder that authenticated users have write access to. A low privileged user can leverage this vulnerability to execute arbitrary code as SYSTEM. Una vulnerabilidad en el cliente VPN de Private Internet Access (PIA) versiones 1.0 de London Trust Media para Windows, podría permitir a un atacante local autenticado ejecutar código arbitrario con privilegios elevados. • https://github.com/mirchr/security-research/blob/master/vulnerabilities/PIA/CVE-2019-12574.txt • CWE-426: Untrusted Search Path •

A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v82 for Linux could allow an authenticated, local attacker to run arbitrary code with elevated privileges. The openvpn_launcher.64 binary is setuid root. This binary executes /opt/pia/openvpn-64/openvpn, passing the parameters provided from the command line. Care was taken to programmatically disable potentially dangerous openvpn parameters; however, the --route-pre-down parameter can be used. This parameter accepts an arbitrary path to a script/program to be executed when OpenVPN exits. • https://github.com/mirchr/security-research/blob/master/vulnerabilities/PIA/CVE-2019-12578.txt • CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •

A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v0.9.8 beta (build 02099) for macOS could allow an authenticated, local attacker to overwrite arbitrary files. When the client initiates a connection, the XML /tmp/pia-watcher.plist file is created. If the file exists, it will be truncated and the contents completely overwritten. This file is removed on disconnect. An unprivileged user can create a hard or soft link to arbitrary files owned by any user on the system, including root. • https://github.com/mirchr/security-research/blob/master/vulnerabilities/PIA/CVE-2019-12571.txt • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v82 for macOS could allow an authenticated, local attacker to run arbitrary code with elevated privileges. The openvpn_launcher binary is setuid root. This program is called during the connection process and executes several operating system utilities to configure the system. The networksetup utility is called using relative paths. A local unprivileged user can execute arbitrary commands as root by creating a networksetup trojan which will be executed during the connection process. • https://github.com/mirchr/security-research/blob/master/vulnerabilities/PIA/CVE-2019-12576.txt • CWE-426: Untrusted Search Path •

A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v82 for Linux and macOS could allow an authenticated, local attacker to overwrite arbitrary files. The openvpn_launcher binary is setuid root. This binary supports the --log option, which accepts a path as an argument. This parameter is not sanitized, which allows a local unprivileged user to overwrite arbitrary files owned by any user on the system, including root. This creates a denial of service condition and possible data loss if leveraged by a malicious local user. • https://github.com/mirchr/security-research/blob/master/vulnerabilities/PIA/CVE-2019-12573.txt • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
