CVE-2024-29319
📋 TL;DR
Volmarg Personal Management System 1.4.64 contains a Server-Side Request Forgery (SSRF) vulnerability that allows attackers to make the server send HTTP and DNS requests to attacker-controlled systems by uploading malicious SVG files. This affects all users running the vulnerable version of the software. Attackers can potentially access internal systems and services that should not be exposed.

📦 What is this software?
Personal Management System by Personal Management System
⚠️ Risk & Real-World Impact
Worst Case
Attackers could use the vulnerable server as a proxy to scan internal networks, access internal services, perform port scanning, or interact with cloud metadata services to obtain credentials and escalate access.
Likely Case
Attackers will use the vulnerability to make the server send requests to external systems they control, potentially exfiltrating data or performing reconnaissance on internal network segments accessible from the server.
If Mitigated
With proper network segmentation and egress filtering, the impact is limited to the server making unauthorized external requests, though internal network access might still be possible.
🎯 Exploit Status
Exploitation requires authenticated access to upload files. The vulnerability is well-documented with public proof-of-concept available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.4.65 or later
Vendor Advisory: https://github.com/Volmarg/personal-management-system
Restart Required: No
Instructions:
1. Backup your current installation. 2. Download the latest version from the official repository. 3. Replace the existing files with the new version. 4. Verify the version number in the system settings.
🔧 Temporary Workarounds
Disable SVG file uploads
allModify the application configuration to reject SVG file uploads entirely
Modify upload validation in the application code to filter out .svg files
Implement strict file type validation
allAdd server-side validation that checks file content, not just extensions
Implement MIME type checking and file signature validation for all uploads
🧯 If You Can't Patch
- Implement network egress filtering to restrict outbound connections from the server
- Deploy a web application firewall (WAF) with SSRF protection rules
🔍 How to Verify
Check if Vulnerable:
Check if running version 1.4.64 of Volmarg Personal Management System and test SVG file upload functionality with SSRF payloadsCheck Version:
Check the version in the application's admin interface or settings pageVerify Fix Applied:
Verify the system version is 1.4.65 or later and test that SVG uploads no longer trigger external requests📡 Detection & Monitoring
Log Indicators:
- Unusual outbound HTTP requests from the server
- Multiple failed SVG upload attempts
- Requests to unusual domains or internal IP addresses
Network Indicators:
- Unexpected outbound HTTP traffic from the application server
- DNS requests to suspicious domains from the server
SIEM Query:
