Description

This security bulletin contains information about 5 vulnerabilities.


1) Improper access control (CVE-ID: CVE-2016-9639)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to obtain potentially sensitive information and write arbitrary files on the target system.

The weakness exists due to improper access control. A remote attacker can read or write to minions with the same id, related to caching.

2) Path traversal (CVE-ID: CVE-2017-12791)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to bypass security restrictions on the target system.

The weakness exists in minion id validation due to path traversal. A remote attacker with incorrect credentials can authenticate to a master via a crafted minion ID.

3) Path traversal (CVE-ID: CVE-2017-14695)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to bypass security restrictions on the target system.

The weakness exists in minion id validation due to path traversal. A remote attacker with incorrect credentials can authenticate to a master via a crafted minion ID.

4) Improper input validation (CVE-ID: CVE-2017-14696)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to improper input validation. A remote attacker can submit a specially crafted authentication request and cause the service to crash.

5) Command injection (CVE-ID: CVE-2017-5200)

CWE-ID: CWE-77 - Command injection

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to execute arbitrary commands on the target system.

The weakness exists in a salt-master due to command injection via Salt's ssh_client. A remote attacker can inject and execute arbitrary commands.
