Recently, a critical vulnerability (CVE-2022-27893) was identified in The Foundry Magritte plugin osisoft-pi-web-connector, affecting versions .15. to .43.. Due to improper logging, the vulnerability could allow an attacker to obtain user authentication details, potentially leading to unauthorized access to sensitive information and systems. In this article, we'll take a deep dive into the details of this vulnerability, explore how it can be exploited, and discuss the steps to mitigate the risk.

Vulnerability Overview

The Foundry Magritte plugin osisoft-pi-web-connector is designed to enable communication between the Magritte application and the OSIsoft PI System.

In versions .15. to .43., it was discovered that the plugin was logging authentication requests, including both usernames and passwords, in plaintext format. As a result, attackers with access to the log files could potentially gain unauthorized access to the targeted systems.

This information disclosure vulnerability was addressed in osisoft-pi-web-connector version .44., which removes sensitive data from log entries, thus helping to protect user credentials.

Exploit Details

Although there are no public exploits for this vulnerability, a potential exploit scenario would involve an attacker gaining access to the log files containing authentication requests. Below is a sample code snippet showcasing the logging of authentication requests in affected versions:

logger.log(Level.INFO, "Processing authentication request: Username: {}, Password: {1}", new Object[] {username, password});

In this example, the 'username' and 'password' are logged as plaintext in the specified log file, making them easily accessible to anyone with access to the logs.

To protect your systems against this vulnerability, follow these steps

1. Update your osisoft-pi-web-connector plugin to version .44.. The updated version resolves the information disclosure issue by removing sensitive data from log entries.

2. Review and remove any log files containing sensitive information, such as plaintext user credentials.

3. Ensure proper monitoring and access controls are in place to prevent unauthorized access to log files.

4. Regularly check for and apply available security patches and updates to keep your systems protected against emerging threats.
