CVE-2025-2538: Understanding the Improper Authentication Vulnerability in Esri ArcGIS Enterprise Deployments

The Common Vulnerabilities and Exposures (CVE) system helps users stay informed about security vulnerabilities in their software. CVE-2025-2538 is a serious vulnerability affecting some deployments of Esri ArcGIS Enterprise, a widely used platform for managing and visualizing spatial data. This post aims at providing a comprehensive description of CVE-2025-2538, the nature of the vulnerability, and how to detect and potentially exploit this security flaw.

The Vulnerability: CVE-2025-2538

CVE-2025-2538 is an improper authentication vulnerability that can allow an attacker to bypass security measures and access the underlying system without valid credentials. In essence, an attacker could gain unauthorized access to sensitive data, manipulate controls, and potentially execute malicious code.

Esri ArcGIS Enterprise is a popular platform for managing and visualizing spatial data used by many organizations worldwide. The improper authentication vulnerability can affect some deployments of the software, depending on the configuration.

Understanding Improper Authentication

Improper authentication occurs when a system fails to properly verify the identity of a user or a system. This failure can result from insufficient validation, bypassing of checks, or incorrect usage of authentication mechanisms.

In the case of CVE-2025-2538, the affected Esri ArcGIS Enterprise deployments do not properly authenticate certain requests, allowing attackers to bypass the required authentication process.

Code Snippet

The following code snippet demonstrates the authentication bypass vulnerability in a simplified way. In this example, the authenticate() function is supposed to verify the credentials provided by a user, returning True if the user is authenticated or False if the authentication fails.

def authenticate(username, password):
    # Check if username and password are correct
    if username == "admin" and password == "password":
        return True
    else:
        return False

def main():
    authenticated = authenticate("admin", "wrong_password")
    if authenticated:
        print("Access granted.")
    else:
-hidden_hashtags-        print("Access denied.")

main()

However, due to the improper authentication vulnerability, the attacker can bypass the credential check and gain access to the system with unauthorized privileges.

Exploit Details

Exploiting CVE-2025-2538 requires access to the affected Esri ArcGIS Enterprise deployment. Attackers can craft malicious requests that bypass the authentication mechanism, allowing them access to sensitive data and system controls.

Unfortunately, the exploitation of this vulnerability can be relatively simple for experienced attackers with knowledge of the target system. For this reason, it is critical to apply any available patches and follow best practices when configuring and deploying Esri ArcGIS Enterprise systems.
