CVE-2024-1819: Codeastro Membership System RCE Flaw

CVE-2024-1819 Overview

CVE-2024-1819 is an unrestricted file upload vulnerability in CodeAstro Membership Management System 1.0. The flaw resides in the Add Members Tab component, where the Member Photo parameter fails to validate uploaded file content. Attackers with high-privilege authentication can upload arbitrary files, including server-side scripts, over the network. The exploit has been publicly disclosed and is tracked as VulDB identifier VDB-254607. This maps to CWE-434: Unrestricted Upload of File with Dangerous Type.

Critical Impact
Successful exploitation allows remote code execution via malicious file upload, compromising confidentiality, integrity, and availability of the affected application.

Technical Details for CVE-2024-1819

Vulnerability Analysis

The vulnerability exists in the Add Members Tab of CodeAstro Membership Management System 1.0. The application accepts file uploads via the Member Photo parameter without enforcing file type, extension, or content validation. An authenticated attacker can substitute an executable server-side script (such as PHP) in place of an image file. Once uploaded, the file can be requested through the web server, resulting in arbitrary code execution in the application context.

The exploit has been disclosed publicly through VulDB, increasing the likelihood of opportunistic abuse against exposed installations. The EPSS score is 0.672%, placing it in the 49th percentile for exploitation probability.

Root Cause

The root cause is missing server-side validation of uploaded files in the member registration workflow. The application relies on client-side controls or file extension checks that attackers can trivially bypass. There is no MIME type verification, magic byte inspection, or restriction on files written to web-accessible directories.

Attack Vector

Exploitation requires network access to the application and authenticated privileges to reach the Add Members Tab. An attacker crafts a multipart form submission containing a malicious script disguised as an image. The web server stores the file in a publicly accessible upload directory. The attacker then invokes the uploaded script via HTTP, achieving remote code execution on the underlying host.

No verified proof-of-concept code is available in public repositories. Refer to the VulDB entry #254607 for additional technical context.

Detection Methods for CVE-2024-1819

Indicators of Compromise

Unexpected files with executable extensions (.php, .phtml, .jsp, .asp) present in member photo upload directories
Web server access logs showing POST requests to the Add Members endpoint followed by GET requests to non-image files in the upload path
Outbound network connections originating from the web server process shortly after file upload activity
Newly created web shells or scheduled tasks on the host running the Membership Management System

Detection Strategies

Inspect the upload directory for files whose extensions or magic bytes do not match image formats
Correlate authenticated administrative sessions with subsequent file writes to web-accessible paths
Alert on web server processes spawning shell interpreters such as sh, bash, or cmd.exe

Monitoring Recommendations

Enable verbose logging of multipart file uploads including original filename, stored path, and MIME type
Monitor filesystem changes in the application's upload directory with integrity checking tools
Track process lineage from the web server to identify anomalous child processes indicative of web shell execution

How to Mitigate CVE-2024-1819

Immediate Actions Required

Restrict access to the Membership Management System administrative interface to trusted networks only
Audit the upload directory for unauthorized files and remove any that do not conform to expected image formats
Rotate credentials for accounts that can access the Add Members Tab to reduce risk from stolen sessions
Disable script execution in directories that store user-uploaded content at the web server configuration level

Patch Information

No vendor advisory or official patch has been published for CodeAstro Membership Management System 1.0 as of the last NVD update on 2026-06-17. Organizations should contact the vendor directly or evaluate alternative membership management platforms. Consult the VulDB CTI entry for status updates.

Workarounds

Deploy a web application firewall rule that inspects uploaded file content and blocks non-image payloads to the Add Members endpoint
Configure the web server to deny script execution within the upload directory using directives such as php_flag engine off or equivalent handler removal
Enforce a strict allowlist of file extensions and validate magic bytes against expected image formats before persisting files
Isolate the application on a segmented network and place it behind an authenticated reverse proxy to limit exposure

bash

# Apache configuration example to disable script execution in uploads directory
<Directory "/var/www/mms/uploads">
