A vulnerability was found in London Trust Media Private Internet Access 0.9.8 Beta Build 02099 on MacOS and classified as critical. Affected by this issue is an unknown functionality of the file /tmp/pia-watcher.plist. The manipulation with an unknown input leads to a link following vulnerability. Using CWE to declare the problem leads to CWE-59. The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. Impacted is confidentiality, integrity, and availability. CVE summarizes:
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. This creates a denial of service condition and possible data loss if leveraged by a malicious local user.
The weakness was presented 07/11/2019. This vulnerability is handled as CVE-2019-12571 since 06/02/2019. The attack needs to be approached locally. The successful exploitation needs a simple authentication. There are known technical details, but no exploit is available.
There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
