CVE-2024-9014: Critical OAuth2 Vulnerability in pgAdmin Versions 8.11 and Earlier

Attention to all users of pgAdmin, a popular open-source administration and management tool for the PostgreSQL database: a critical security vulnerability (CVE-2024-9014) has been discovered in pgAdmin versions 8.11 and earlier. This vulnerability impacts the OAuth2 authentication mechanism and, if exploited, can allow a malicious attacker to potentially obtain the client ID and secret. As a result, unauthorized access to user data is possible, leading to severe security risks.

In this lengthy read, we dive into the technical details of this vulnerability, provide code snippets to demonstrate its impact, and offer guidance on how to mitigate potential threats. We also link to original references to help you stay informed and protected.

The Core Issue: OAuth2 Vulnerability

OAuth2 is a widely-used authorization framework that provides secure access to protected resources. It is commonly used for granting access to third-party applications without requiring users to share their credentials. However, in the case of pgAdmin versions 8.11 and earlier, there is a security flaw in the OAuth2 implementation that can be exploited by attackers.

When an OAuth2 client (i.e., a third-party application) requests access to protected resources, it must provide a client ID and a client secret to authenticate itself. The core issue with pgAdmin v8.11 and earlier is that these sensitive credentials can be exposed if an attacker can intercept or manipulate the OAuth2 authorization process.

Code Snippet Illustrating Vulnerability

The following code snippet illustrates the OAuth2 implementation in pgAdmin v8.11 (please note that this has been simplified for clarity):

class OAuth2Handler:
  def get_client_credentials(self):
    
    client_id = 'hardcoded_client_id'
    client_secret = 'hardcoded_client_secret'
    
    return client_id, client_secret

As we can see, the get_client_credentials function returns a hardcoded client_id and client_secret. Because these credentials are hardcoded, they remain constant across all instances of the application, allowing attackers to potentially obtain and misuse them.

Identify a vulnerable instance of pgAdmin (v8.11 or earlier).

2. Study the OAuth2 implementation in the target application and identify the hardcoded client ID and secret.
