SaltStack reports:

Improper handling of clear messages on the minion, which could result in executing commands not sent by the master.

ge 2015.8.0 lt 2015.8.4

SaltStack reports:

Correct a flaw in minion id validation which could allow certain minions to authenticate to a master despite not having the correct credentials. To exploit the vulnerability, an attacker must create a salt-minion with an ID containing characters that will cause a directory traversal.

Remote command execution and incorrect access control when using salt-api.

Directory traversal vulnerability when using salt-api. Allows an attacker to determine what files exist on a server when querying /run or /events.

SaltStack reports:

Directory traversal vulnerability in minion id validation in SaltStack. Allows remote minions with incorrect credentials to authenticate to a master via a crafted minion ID. Credit for discovering the security flaw goes to: Julian Brost (julian@0x4a42.net). NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-12791.

Remote Denial of Service with a specially crafted authentication request. Credit for discovering the security flaw goes to: Julian Brost (julian@0x4a42.net)

CVE-2020-11651 - Authentication bypass vulnerabilities

The ClearFuncs class processes unauthenticated requests and unintentionally exposes the _send_pub() method, which can be used to queue messages directly on the master publish server. Such messages can be used to trigger minions to run arbitrary commands as root.

The ClearFuncs class also exposes the method _prep_auth_info(), which returns the "root key" used to authenticate commands from the local root user on the master server. This "root key" can then be used to remotely call administrative commands on the master server. This unintentional exposure provides a remote un-authenticated attacker with root-equivalent access to the salt master.

CVE-2020-11652 - Directory traversal vulnerabilities

The wheel module contains commands used to read and write files under specific directory paths. The inputs to these functions are concatenated with the target directory and the resulting path is not canonicalized, leading to an escape of the intended path restriction.

The get_token() method of the salt.tokens.localfs class (which is exposed to unauthenticated requests by the ClearFuncs class) fails to sanitize the token input parameter which is then used as a filename, allowing insertion of ".." path elements and thus reading of files outside of the intended directory. The only restriction is that the file has to be deserializable by salt.payload.Serial.loads().

SaltStack reports:

This issue affects all Salt versions prior to 2015.8.8/2015.5.10 when PAM external authentication is enabled. This issue involves passing an alternative PAM authentication service with a command that is sent to LocalClient, enabling the attacker to bypass the configured authentication service.

SaltStack reports:

With the Salt NetAPI enabled in addition to having a SSH roster defined, unauthenticated access is possible when specifying the client as SSH.

Additionally, when the raw_shell option is specified any arbitrary command may be run on the Salt master when specifying SSH options.
