Technical Details for CVE-2024-53677

Vulnerability Analysis

The vulnerability arises from improper file upload parameter handling, allowing attackers to perform path traversal. This can lead to the upload of malicious files, potentially enabling remote code execution.

Root Cause

The root cause is the flawed logic in the FileuploadInterceptor, which improperly sanitizes file paths during upload.

Attack Vector

The vulnerability can be exploited remotely via network access by sending crafted file upload requests.

java

// Example exploitation code (sanitized)
public void exploit(StrutsRequest req) {
    req.addFile("../../../../malicious.jar");
    req.send();
}

Detection Methods for CVE-2024-53677

Indicators of Compromise

Malicious file uploads with unexpected paths
Suspicious file creation under application directories
Anomalous application behavior or crashes

Detection Strategies

Utilize intrusion detection systems (IDS) to monitor for unusual file upload patterns, and employ file integrity checks on server directories.

Monitoring Recommendations

Continuously monitor log files for irregular file upload requests and implement alerts for unauthorized access attempts.

How to Mitigate CVE-2024-53677

Immediate Actions Required

Upgrade to Apache Struts version 6.4.0 or later
