CVE-2024-1735 - Armeria-SAML Vulnerability Allows Authentication Bypass: Know the Risks, Update Now

In today's interconnected world, it is crucial to keep our systems and software updated to stay ahead of cybercriminals. One such area is Armeria-SAML, a crucial component for many applications that rely on SAML authentication. Recently, a significant vulnerability has been discovered with potentially far-reaching consequences. If you are using armeria-saml versions less than 1.27.2, it's time to pay attention and take action.

CVE-2024-1735: Armeria-SAML Authentication Bypass Vulnerability

A serious vulnerability has been identified in armeria-saml versions less than 1.27.2, which can lead to the bypassing of authentication using malicious SAML messages. If exploited successfully, this vulnerability can have severe consequences, including unauthorized access to your systems by cybercriminals.

CVE-2024-1735 details can be found at the official reference

https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-1735

Below is a code snippet to demonstrate the issue in armeria-saml

HttpAuthServiceBuilder samlAuth = new HttpAuthServiceBuilder(requestContext -> {
// ... process the request ...
}, loginTimeout, cookieName);
  
try {
    SAMLMessageContext context = samlHandler.extractSAMLMessageContext(xmlObject);
    if (samlHandler.verifySAMLMessage(context)) {
        return samlHandler.authenticate(requestContext, context);
    } else {
        return HttpResponse.of(HttpStatus.UNAUTHORIZED);
    }
} catch (Exception e) {
    return  HttpResponse.of(HttpStatus.UNAUTHORIZED);
}

In the code above, the verifySAMLMessage method checks if the SAML message is legitimate. However, the vulnerability allows the use of malicious SAML messages to bypass this check, leading to unauthorized access.

Exploit Details

In order to exploit this vulnerability, an attacker would first need to craft a malicious SAML message that bypasses the checks put in place by the verifySAMLMessage method. With the bypass in place, the attacker could potentially gain unauthorized access to the target system, which could lead to data breaches, system compromise, and other severe consequences if not properly addressed.

Addresses This Issue

All users who rely on armeria-saml older than version 1.27.2 must upgrade as soon as possible to protect their systems. Upgrading to the latest version 1.27.2 or later will help to mitigate the risk and safeguard your applications from unauthorized access. The latest version can be found here:
