Arch Linux Security Advisory ASA-202102-33 ========================================== Severity: High Date : 2021-02-27 CVE-ID : CVE-2020-28243 CVE-2020-28972 CVE-2020-35662 CVE-2021-3144 CVE-2021-3148 CVE-2021-3197 CVE-2021-25281 CVE-2021-25282 CVE-2021-25283 CVE-2021-25284 Package : salt Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1624 Summary ======= The package salt before version 3002.5-3 is vulnerable to multiple issues including access restriction bypass, arbitrary command execution, certificate verification bypass, cross-site scripting, insufficient validation, privilege escalation, directory traversal and information disclosure. Resolution ========== Upgrade to 3002.5-3. # pacman -Syu "salt>=3002.5-3" The problems have been fixed upstream in version 3002.5. Workaround ========== None. Description =========== - CVE-2020-28243 (privilege escalation) An issue was discovered in SaltStack Salt before 3002.5. The minion's restartcheck is vulnerable to command injection via a crafted process name. This allows for a local privilege escalation by any user able to create files on the minion in a non-blacklisted directory. - CVE-2020-28972 (certificate verification bypass) In SaltStack Salt before 3002.5, authentication to VMware vcenter, vsphere, and esxi servers (in the vmware.py files) does not always validate the SSL/TLS certificate. - CVE-2020-35662 (certificate verification bypass) In SaltStack Salt before 3002.5, when authenticating to services using certain modules, the SSL certificate is not always validated. - CVE-2021-3144 (insufficient validation) In SaltStack Salt before 3002.5, eauth tokens can be used once after expiration. (They might be used to run command against the salt master or minions.) - CVE-2021-3148 (arbitrary command execution) An issue was discovered in SaltStack Salt before 3002.5. Sending crafted web requests to the Salt API can result in salt.utils.thin.gen_thin() command injection because of different handling of single versus double quotes. This is related to salt/utils/thin.py. - CVE-2021-3197 (arbitrary command execution) An issue was discovered in SaltStack Salt before 3002.5. The salt-api's ssh client is vulnerable to a shell injection by including ProxyCommand in an argument, or via ssh_options provided in an API request. - CVE-2021-25281 (access restriction bypass) An issue was discovered in SaltStack Salt before 3002.5. salt-api does not honor eauth credentials for the wheel_async client. Thus, an attacker can remotely run any wheel modules on the master. - CVE-2021-25282 (directory traversal) An issue was discovered in SaltStack Salt before 3002.5. The salt.wheel.pillar_roots.write method is vulnerable to directory traversal. - CVE-2021-25283 (cross-site scripting) An issue was discovered in SaltStack Salt before 3002.5. The jinja renderer does not protect against server side template injection attacks. - CVE-2021-25284 (information disclosure) An issue was discovered in SaltStack Salt before 3002.5. salt.modules.cmdmod can log credentials to the info or error log level. Impact ====== A remote unauthenticated attacker could execute commands, bypass TLS verification, traverse directories and disclose credentials.
