Description Preview
CVE-2021-42082 is a privilege escalation vulnerability in OSNEXUS QuantaStor software-defined storage solution. The vulnerability allows local users to execute scripts under root privileges, which could lead to complete system compromise. This is classified as CWE-269 (Improper Privilege Management). The issue was discovered and reported by the Dutch Institute for Vulnerability Disclosure (DIVD).
Overview
OSNEXUS QuantaStor is a software-defined storage platform used in enterprise environments. The vulnerability allows unprivileged local users to escalate their privileges by executing scripts with root permissions. This could enable attackers who have already gained access to a system to obtain full administrative control, potentially compromising the entire storage infrastructure and any data stored within it. The vulnerability represents a serious security risk as it bypasses the normal security boundaries between user and administrative privileges.
Remediation
Organizations using OSNEXUS QuantaStor should:
- Apply the latest security patches provided by OSNEXUS as soon as possible
- Restrict local access to QuantaStor systems to only authorized personnel
- Implement network segmentation to limit access to storage management interfaces
- Monitor systems for suspicious activities, especially any attempts to execute unauthorized scripts
- Contact OSNEXUS support for specific guidance if patches cannot be applied immediately
- Review system logs for any signs of exploitation
