A vulnerability.
When org.apache.linkis.metadata.util.HiveUtils.decode() fails to perform Base64 decoding, it records the complete input parameter string in the log via logger.error(str + "decode failed", e). If the input parameter contains sensitive information such as Hive Metastore keys, plaintext passwords will be left in the log files when decoding fails, resulting in information leakage.
Affected Scope
Component: Sensitive fields in hive-site.xml (e.g., javax.jdo.option.ConnectionPassword) or other fields encoded in Base64.
Version: Apache Linkis 1.0.0 – 1.7.0
Trigger Conditions
The value of the configuration item is an invalid Base64 string.
Log files are readable by users other than hive-site.xml administrators.
Severity: Low
The probability of Base64 decoding failure is low.
The leakage is only triggered when logs at the Error level are exposed.
Remediation
Apache Linkis 1.8.0 and later versions have replaced the log with desensitized content.
logger.error("URL decode failed: {}", e.getMessage()); // 不再输出 str
Users are recommended to upgrade to version 1.8.0, which fixes the issue.

In Apache Linkis <1.7.0, due to the lack of effective filtering
of parameters, an attacker configuring malicious Mysql JDBC parameters in the DataSource Manager Module will
allow the attacker to read arbitrary files from the Linkis server. Therefore, the parameters in the Mysql JDBC URL should be blacklisted. This attack requires the attacker to obtain an authorized account from Linkis before it can be carried out. Versions of Apache Linkis < 1.7.0 will be affected.
We recommend users upgrade the version of Linkis to version 1.7.0.

In Apache Linkis <=1.3.1, due to the default token generated by Linkis Gateway deployment being too simple, it is easy for attackers to obtain the default token for the attack. Generation rules should add random values.
We recommend users upgrade the version of Linkis to version 1.3.2 And modify the default token value. You can refer to Token authorization[1]

In Apache Linkis <=1.3.1, because the parameters are not
effectively filtered, the attacker uses the MySQL data source and malicious parameters to
configure a new data source to trigger a deserialization vulnerability, eventually leading to
remote code execution.

In Apache Linkis <=1.3.0 when used with the MySQL Connector/J, a deserialization vulnerability with possible remote code execution impact exists when an attacker has write access to a database and configures new datasource with a MySQL data source and malicious parameters. Therefore, the parameters in the jdbc url should be blacklisted. Versions of Apache Linkis <= 1.3.0 will be affected.
We recommend users to upgrade the version of Linkis to version 1.3.1.
