Hackers Exploit Tomcat Vulnerability to Hijack Apache Servers

A recent and significant cybersecurity threat has emerged involving a critical vulnerability in Apache Tomcat, identified as CVE-2025-24813.

This vulnerability allows for remote code execution, potentially allowing hackers to hijack servers running Apache Tomcat.

The exploitation of this vulnerability is a serious concern, as it could lead to widespread unauthorized access and malicious activities on compromised systems.

CVE-2025-24813: Understanding the Vulnerability

CVE-2025-24813 is described as a remote code execution vulnerability in Apache Tomcat.

According to the GitHub report, this security flaw can be exploited by sending specially crafted requests to vulnerable servers, allowing attackers to execute arbitrary code.

The nature of this vulnerability makes it particularly dangerous because it can be exploited remotely, meaning attackers do not need physical or network access to the targeted servers.

The impact of CVE-2025-24813 could be substantial. If exploited successfully, it would grant attackers full control over the server, allowing them to install malware, steal sensitive data, or disrupt service operations.

This could affect not just the security of the server but also the privacy and integrity of data stored or processed by the server.

Proof of Concept (PoC) Exploitation

A proof-of-concept (PoC) script has been made available to demonstrate the vulnerability.

This script is intended for network security research and educational purposes only. It is used to test whether a system is vulnerable to CVE-2025-24813.

The script supports batch detection with multi-threading capabilities, allowing security professionals to quickly identify vulnerable systems across large networks.

# Batch detection with multi-threading support:

python poc.py -l url.txt -t 5

# Single host detection:

python poc.py -u your-ip

The exploitation steps and tools associated with CVE-2025-24813 are purely for educational purposes.

These tools mustn’t be used for unauthorized testing or malicious activities. All testing must be conducted on systems where explicit permission has been granted.

To protect against exploits of CVE-2025-24813, organizations should take immediate action:

1. Update Apache Tomcat: Ensure all Tomcat installations are updated to the latest version, which should include patches for this vulnerability.
2. Implement Network Monitoring: Regularly monitor network traffic and server logs for signs of unauthorized activity.
3. Use Security Tools: Utilize intrusion detection systems and firewalls to block suspicious requests.
4. Limit Access: Implement strict access controls to limit who can interact with server configurations and code.

The exploitation of vulnerabilities like CVE-2025-24813 underscores the importance of maintaining robust cybersecurity practices.

Regular updates, proper network monitoring, and strict access controls are essential in preventing server hijacks and protecting sensitive data.

As the threat landscape continues to evolve, proactive measures are crucial for safeguarding digital assets.
