Description

Apache Linkis: Password Exposure

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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity none, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: None.
  • Availability impact: None.
