CVE-2025-59355

/// Technical description

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.
