Hello LinuxPatch users!

Today, we're delving into a significant cybersecurity vulnerability identified as CVE-2020-11652. This vulnerability has been classified with a severity rating of MEDIUM and an associated score of 6.5 according to industry standard metrics. Our main aim is to dissect what this CVE entails, the susceptible software, and the steps you should take to mitigate the risk.

CVE-2020-11652 primarily affects SaltStack Salt, a powerful configuration management and remote execution software. Salt is widely used in various IT environments to automate the management of servers, making it crucial to maintain the software's security integrity.

The core of the issue lies in the salt-master process's ClearFuncs class, which allows authenticated users improper access to methods that do not correctly sanitize paths. This flaw permits these users potential arbitrary directory access. In simpler terms, it could allow an intruder with basic user rights to access or modify locations on the server that should be restricted, possibly leading to further exploitability such as data theft or loss, and unauthorized system changes.

The affected versions include SaltStack Salt before 2019.2.4 and 3000 before 3000.2. Users running these versions are urged to upgrade immediately to the patched versions to prevent exploitation of this vulnerability.
