CVE-2024-41995
📋 TL;DR
This vulnerability in Java Platform versions 12.89 and earlier uses insecure default TLS settings, potentially exposing affected Ricoh MFPs and printers to known TLS 1.0/1.1 weaknesses. Attackers could exploit this to intercept or manipulate network communications. Organizations using vulnerable Ricoh devices with Java Platform are affected.
💻 Affected Systems
- Ricoh MFPs and printers containing Java Platform
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Man-in-the-middle attacks allowing interception of sensitive print jobs, authentication credentials, or device management communications, potentially leading to data theft or unauthorized device access.
Likely Case
Network eavesdropping on unencrypted or weakly encrypted communications between the device and management systems, potentially exposing print job contents or configuration data.
If Mitigated
Limited impact if network segmentation isolates devices and strong TLS configurations are enforced externally.
🎯 Exploit Status
Exploitation requires network access to the device and leverages known TLS 1.0/1.1 weaknesses rather than a new exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Java Platform version newer than 12.89
Vendor Advisory: https://jp.ricoh.com/security/products/vulnerabilities/vul?id=ricoh-2024-000010
Restart Required: Yes
Instructions:
1. Check specific Ricoh device model against vendor advisory. 2. Apply firmware updates provided by Ricoh. 3. Restart affected devices after patching. 4. Verify TLS configuration post-update.
🔧 Temporary Workarounds
Disable TLS 1.0 and 1.1
allConfigure devices to use only TLS 1.2 or higher if supported by the Java Platform version.
Network Segmentation
allIsolate vulnerable devices in separate network segments with restricted access.
🧯 If You Can't Patch
- Implement network-level TLS inspection/termination using secure proxies
- Monitor network traffic to/from affected devices for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check Java Platform version on Ricoh devices via web interface or management console, or consult Ricoh's vulnerability list for specific affected models.Check Version:
Device-specific; typically through Ricoh web interface or embedded management tools.Verify Fix Applied:
Verify Java Platform version is >12.89 and test TLS connections to ensure only TLS 1.2+ is accepted.📡 Detection & Monitoring
Log Indicators:
- Failed TLS handshake attempts
- Unexpected protocol downgrade events
- Multiple connection attempts using older TLS versions
Network Indicators:
- TLS 1.0/1.1 handshakes to Ricoh devices
- Unusual outbound connections from printers/MFPs
