📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete server compromise allowing remote code execution, data theft, lateral movement, and persistent backdoor installation.

🟠

Likely Case

Web shell upload leading to unauthorized access, file system manipulation, and potential data exfiltration.

🟢

If Mitigated

File uploads blocked or properly validated, limiting attack surface to other potential vulnerabilities.

🌐 Internet-Facing: HIGH - Web applications with file upload functionality exposed to internet are prime targets.
🏢 Internal Only: MEDIUM - Internal attackers could still exploit this to gain elevated privileges.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires authenticated access but is straightforward once access is obtained.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Versions after 06.7.22

Vendor Advisory: https://borelenzo.github.io/stuff/2023/06/01/cve-2023-3032.html

Restart Required: Yes

Instructions:

1. Contact Mobatime vendor for patched version. 2. Backup current installation. 3. Apply vendor-provided patch or upgrade to version after 06.7.22. 4. Restart web application services.

🔧 Temporary Workarounds

File Upload Restriction

all

Implement strict file type validation and whitelist acceptable file extensions

Web Application Firewall Rules

all

Configure WAF to block file uploads with dangerous extensions (.php, .jsp, .asp, etc.)

🧯 If You Can't Patch

  • Disable documentary proof upload modules completely
  • Implement network segmentation to isolate Mobatime servers from critical systems

🔍 How to Verify

Check if Vulnerable:

Check Mobatime web application version in admin interface or configuration files. If version is 06.7.22 or earlier, system is vulnerable.

Check Version:

Check application configuration or admin panel for version information

Verify Fix Applied:

Verify version is after 06.7.22 and test file upload functionality with restricted file types.

📡 Detection & Monitoring

Log Indicators:

  • Unusual file uploads to documentary proof modules
  • Files with web shell extensions (.php, .jsp, .asp) being uploaded
  • Multiple failed upload attempts with suspicious filenames

Network Indicators:

  • HTTP POST requests to upload endpoints with unusual file types
  • Subsequent connections to uploaded files from external IPs

SIEM Query:

source="web_server_logs" AND (uri="*upload*" OR uri="*documentary*" OR uri="*proof*") AND (filename="*.php" OR filename="*.jsp" OR filename="*.asp")
