CVE-2024-52316 is a critical vulnerability found in Apache Tomcat, with a CVSS score of 9.8. This vulnerability allows attackers to bypass the authentication process if Tomcat is configured to use a custom Jakarta Authentication component that does not set an HTTP status to indicate failure when an exception occurs during authentication. As a result, the authentication may not fail, which poses significant risks to organizations utilizing affected versions of Tomcat.
The vulnerability affects multiple versions of Apache Tomcat, including versions from 11.0.0-M1 to 11.0.0-M26, 10.1.0-M1 to 10.1.30, and 9.0.0-M1 to 9.0.95. Additionally, older versions that have reached end-of-life (EOL) status, such as 8.5.0 to 8.5.100, may also be affected. Organizations utilizing these versions should take immediate action.
The urgency for defenders is high; organizations should prioritize patching immediately to prevent unauthorized access. Users are advised to upgrade to version 11.0.0, 10.1.31, or 9.0.96, as these versions contain fixes for the vulnerability.
Given the critical nature of this vulnerability and its potential impact, security teams must ensure that they are using patched versions of Tomcat to mitigate risks effectively.
Vulnerability Details
The unchecked error condition vulnerability in Apache Tomcat can lead to an authentication bypass. If a custom Jakarta Authentication ServerAuthContext component is configured without proper error handling, the authentication process may fail to indicate an error, allowing unauthorized users to access protected resources. This vulnerability highlights the importance of rigorous error handling in authentication mechanisms.
The CVSS score of 9.8 categorizes this vulnerability as critical, indicating a severe threat that can lead to unauthorized access. The vulnerability affects various versions of Apache Tomcat, and it is crucial for organizations to remain vigilant and apply necessary updates.
The following CWE classifications apply: CWE-391 (Unchecked Error Condition) and CWE-754 (Improper Check for Unusual or Exceptional Conditions). The continuous monitoring and response to such vulnerabilities are essential for maintaining security.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of error conditions during the authentication process. When an exception is thrown by the Jakarta Authentication component, if it does not set an appropriate HTTP status, the system may incorrectly allow access without proper validation.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely without physical access to the target system. The attack complexity is low, and no special privileges or user interaction are required to exploit this vulnerability, making it particularly dangerous.
The impact of this vulnerability is significant, with high consequences for confidentiality, integrity, and availability. Attackers may leverage this weakness to gain unauthorized access to sensitive information, potentially leading to data breaches and loss of user trust.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to restricted areas of applications using affected versions of Apache Tomcat. The potential blast radius for this vulnerability is broad, affecting any organization that relies on these components for authentication.
As this vulnerability is critical, organizations should address it in their priority patch cycle. Failing to remediate this issue could result in significant reputational damage and financial loss due to potential data breaches.
In conclusion, organizations must remain proactive in their security measures and ensure they are operating on the latest versions of affected software. Continuous monitoring and assessment of security posture are essential to mitigate risks associated with vulnerabilities like CVE-2024-52316.
