#auth

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.

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).

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.

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.

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.

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.

### Impact The JWT secret key in the vantage6 server is auto-generated unless defined by the user. The auto-generated key is a UUID1, which is not cryptographically secure as it is [predictable to some extent](https://docs.python.org/3/library/uuid.html#uuid.uuid1) ### Patches No ### Workarounds You may define JWT secret key in the server configuration file

### Impact If attacker gets access to an authenticated session, they can try to brute-force the user password by using the change password functionality: they can call that route infinitely which will return the message that password is wrong until it is correct ### Patches This issue has been patched in version 4.11.0 ### Workarounds None

### Impact It's possible to execute any SQL query in Oracle by using the function like [DBMS_XMLGEN or DBMS_XMLQUERY](https://docs.oracle.com/en/database/oracle/oracle-database/19/arpls/DBMS_XMLGEN.html). The XWiki query validator does not sanitize functions that would be used in a simple `select` and Hibernate allows using any native function in an HQL query. ### Patches This has been patched in 16.10.2, 16.4.7 and 15.10.16. ### Workarounds There is no known workaround, other than upgrading XWiki. ### References https://jira.xwiki.org/browse/XWIKI-22734 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) * Email us at [Security Mailing List](mailto:[email protected])
