CVE-2019-11771 Explained : Impact and Mitigation
Learn about CVE-2019-11771 affecting Eclipse OpenJ9 versions before 0.15.0 on AIX. Discover the risks of code injection and privilege escalation by local users and how to mitigate the vulnerability.
Eclipse OpenJ9 versions prior to 0.15.0 on AIX operating system have unused RPATHs that could potentially enable local users to inject code and elevate privileges.
Understanding CVE-2019-11771
A vulnerability in Eclipse OpenJ9 versions before 0.15.0 on AIX systems could allow local users to inject malicious code and escalate privileges.
What is CVE-2019-11771?
This CVE refers to the presence of unused RPATHs in Eclipse OpenJ9 versions earlier than 0.15.0 on AIX, which may be exploited by local users to execute arbitrary code and gain elevated privileges.
The Impact of CVE-2019-11771
The vulnerability could lead to unauthorized code execution and privilege escalation by local users on affected systems.
Technical Details of CVE-2019-11771
AIX builds of Eclipse OpenJ9 before version 0.15.0 contain unused RPATHs that may facilitate code injection and privilege elevation by local users.
Vulnerability Description
The issue stems from the presence of unused RPATHs in the affected versions, creating a potential security risk for local users to exploit.
Affected Systems and Versions
- Product: Eclipse OpenJ9
- Vendor: The Eclipse Foundation
- Versions Affected: < 0.15.0
Exploitation Mechanism
Local users on AIX systems running vulnerable versions of Eclipse OpenJ9 could inject malicious code through the unused RPATHs, leading to privilege escalation.
Mitigation and Prevention
Immediate Steps to Take:
- Update Eclipse OpenJ9 to version 0.15.0 or newer to mitigate the vulnerability.
- Monitor system logs for any suspicious activities that could indicate exploitation.
Long-Term Security Practices:
- Implement the principle of least privilege to restrict user access and actions.
- Regularly audit and review system configurations to identify and address security weaknesses.
- Educate users on safe computing practices and the risks associated with code injection.
Patching and Updates
Ensure timely patching of software and systems to address known vulnerabilities and enhance overall security.
