Path traversal in saltstack
A specially crafted url can be created which leads to a directory traversal in the salt file server.
A malicious user can read an arbitrary file from a Salt master’s filesystem.

Salt's salt.auth.pki module does not properly authenticate callers
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 attempt to be accepted.

Salt's on demand pillar functionality vulnerable to arbitrary command injections
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.

Salt allows arbitrary directory creation or file deletion
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.

Salt has minion event bus authorization bypass vulnerability
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).

Directory creation by malicious user in saltstack
Syndic cache directory creation is vulnerable to a directory traversal attack in salt project which can lead a malicious attacker to create an arbitrary directory on a Salt master.

Salt's file contents overwrite the VirtKey class
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 is present in the default configuration.

Salt vulnerable to directory traversal attack in minion file cache creation
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.

Salt vulnerable to directory traversal attack in file receiving method
Directory traversal vulnerability in recv_file method allows arbitrary files to be written to the master cache directory.

Salt's worker process vulnerable to denial of service through file read operation
Worker process denial of service through file read operation. .A vulnerability exists in the Master's “pub_ret” method which is exposed to all minions. The un-sanitized input value “jid” is used to construct a path which is then opened for reading. An attacker could exploit this vulnerabilities by attempting to read from a filename that will not return any data, e.g. by targeting a pipe node on the proc file system.

Salt vulnerable to arbitrary event injection
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.

Salt junos Module Vulnerable to Code Injection via Specially Crafted YAML Payload
Salt's junos execution module contained an unsafe YAML decode/load usage. A specially crafted YAML payload processed by the junos module could lead to unintended code execution under the context of the Salt process.

Salt preflight script could be attacker controlled
The Salt-SSH pre-flight option copies the script to the target at a predictable path, which allows an attacker to force Salt-SSH to run their script. If an attacker has access to the target VM and knows the path to the pre-flight script before it runs they can ensure Salt-SSH runs their script with the privileges of the user running Salt-SSH. Do not make the copy path on the target predictable and ensure we check return codes of the scp command if the copy fails.
