Apache Flume vulnerable to remote code execution via deserialization of unsafe providerURL

Critical severity GitHub Reviewed Published Oct 26, 2022 to the GitHub Advisory Database • Updated Jul 28, 2023

Package

maven org.apache.flume.flume-ng-sources:flume-jms-source (Maven)

Affected versions

< 1.11.0

Patched versions

1.11.0

Description

Flume’s JMSSource class can be configured with a providerUrl parameter. A JNDI lookup is performed on this name without performing validation. This could result in untrusted data being deserialized, leading to remote code execution (RCE) attack when a configuration uses a JMS Source with an unsafe providerURL. This issue is fixed in version 1.11.0.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
