File contents overwrite the VirtKey class is called when “on-demand pillar” data is requested and uses un-validated input to create paths to the “pki directory”. The functionality is used to auto-accept Minion authentication keys based on a pre-placed “authorization file” at a specific location and…

Arbitrary directory creation or file deletion. In the find_file method of the GitFS class, a path is created using os.path.join using unvalidated input from the “tgt_env” variable. This can be exploited by an attacker to delete any file on the Master's process has permissions to.

Arbitrary event injection on Salt Master. The master's "_minion_event" method can be used by and authorized minion to send arbitrary events onto the master's event bus.

Directory traversal attack in minion file cache creation. The master's default cache is vulnerable to a directory traversal attack. Which could be leveraged to write or overwrite 'cache' files outside of the cache directory.

An attacker with access to a minion key can exploit the 'on demand' pillar functionality with a specially crafted git url which could cause and arbitrary command to be run on the master with the same privileges as the master process.

Minion event bus authorization bypass. An attacker with access to a minion key can craft a message which may be able to execute a job on other minions (>= 3007.0).

The salt.auth.pki module does not properly authenticate callers. The "password" field contains a public certificate which is validated against a CA certificate by the module. This is not pki authentication, as the caller does not need access to the corresponding private key for the authentication a…

Salt's request server is vulnerable to replay attacks when not using a TLS encrypted transport.

The Game Review Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘className’ parameter in all versions up to, and including, 4.8.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level ac…

Multiple methods in the salt master skip minion token validation. Therefore a misbehaving minion can impersonate another minion.
