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.
Directory traversal vulnerability in recv_file method allows arbitrary files to be written to the master cache directory.
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.
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.
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 attempt to be accepted.
Salt's request server is vulnerable to replay attacks when not using a TLS encrypted transport.
Multiple methods in the salt master skip minion token validation. Therefore a misbehaving minion can impersonate another minion.
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.
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.
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.
Git Providers can read from the wrong environment because they get the same cache directory base name in Salt masters prior to 3005.2 or 3006.2. Anything that uses Git Providers with different environments can get garbage data or the wrong data, which can lead to wrongful data disclosure, wrongful executions, data corruption and/or crash.
Salt masters prior to 3005.2 or 3006.2 contain a DOS in minion return. After receiving several bad packets on the request server equal to the number of worker threads, the master will become unresponsive to return requests until restarted.
Open redirect vulnerability in Tornado versions 6.3.1 and earlier allows a remote unauthenticated attacker to redirect a user to an arbitrary web site and conduct a phishing attack by having user access a specially crafted URL.
An issue was discovered in SaltStack Salt in versions before 3002.9, 3003.5, 3004.2. PAM auth fails to reject locked accounts, which allows a previously authorized user whose account is locked still run Salt commands when their account is locked. This affects both local shell accounts with an active session and salt-api users that authenticate via PAM eauth.
