CVE-2022-25167 : Vulnerability Insights and Analysis
Discover the details of CVE-2022-25167 affecting Apache Flume versions 1.4.0 through 1.9.0, allowing remote code execution through a JNDI LDAP data source URI. Learn the impact, mitigation steps, and prevention measures.
Apache Flume versions 1.4.0 through 1.9.0 are vulnerable to a remote code execution (RCE) attack when a configuration uses a JMS Source with a JNDI LDAP data source URI with an attacker controlling the target LDAP server. The vulnerability is fixed by restricting JNDI to only allow the use of the java protocol or no protocol.
Understanding CVE-2022-25167
This section delves into the intricacies of the CVE-2022-25167 vulnerability in Apache Flume.
What is CVE-2022-25167?
CVE-2022-25167 highlights a security flaw in Apache Flume versions 1.4.0 through 1.9.0 that exposes systems to remote code execution through a JNDI LDAP data source URI.
The Impact of CVE-2022-25167
The vulnerability poses a moderate risk, allowing attackers to execute malicious code remotely when manipulating the JMS Source with a malicious JNDI URI.
Technical Details of CVE-2022-25167
In this section, we explore the technical aspects of CVE-2022-25167.
Vulnerability Description
The vulnerability arises when improper input validation occurs in configurations using a JMS Source with a JNDI LDAP data source URI.
Affected Systems and Versions
Apache Flume versions 1.4.0 to 1.9.0 are affected, specifically when using the 'flume-jms-source' version less than 1.10.0.
Exploitation Mechanism
Attackers exploit the vulnerability by gaining control of the target LDAP server, enabling them to execute remote code via the JMS Source.
Mitigation and Prevention
Protecting systems from CVE-2022-25167 requires immediate actions and long-term security measures.
Immediate Steps to Take
Immediately update Apache Flume to versions beyond 1.9.0 and restrict JNDI to permit only the use of the java protocol or no protocol.
Long-Term Security Practices
Adopt best security practices, such as network segmentation, least privilege access, and regular security audits to prevent similar vulnerabilities.
Patching and Updates
Regularly monitor for security updates from Apache Flume and apply patches promptly to mitigate the risk of exploitation.
