CVE-2025-2820

6.5 MEDIUM

📋 TL;DR

An authenticated attacker can cause a denial-of-service condition on affected Bizerba devices via network access, disrupting normal operations. This affects systems running vulnerable Bizerba software where an attacker has valid credentials.

💻 Affected Systems

Products:
  • Bizerba devices and software
Versions: Specific versions not detailed in reference, check vendor advisory
Operating Systems: Embedded systems on Bizerba hardware
Default Config Vulnerable: ⚠️ Yes
Notes: Requires authenticated access, but default configurations may be vulnerable if standard credentials are used.

⚠️ 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).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete service disruption making the device unavailable for normal operations, potentially impacting business processes.

🟠

Likely Case

Temporary service interruption requiring device restart to restore functionality.

🟢

If Mitigated

Minimal impact with proper network segmentation and authentication controls limiting attack surface.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires authenticated access but appears straightforward based on CVSS and description.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check vendor advisory for specific patched versions

Vendor Advisory: https://www.bizerba.com/downloads/global/information-security/2025/bizerba-sa-2025-0002.pdf

Restart Required: Yes

Instructions:

1. Review vendor advisory 2. Download appropriate patch 3. Apply patch following vendor instructions 4. Restart affected devices

🔧 Temporary Workarounds

Network segmentation

all

Restrict network access to Bizerba devices to only authorized management networks

Authentication hardening

all

Implement strong authentication policies and disable default credentials

🧯 If You Can't Patch

  • Implement strict network access controls to limit which systems can communicate with Bizerba devices
  • Monitor for authentication attempts and unusual network traffic patterns to affected devices

🔍 How to Verify

Check if Vulnerable:

Check device version against vendor advisory and verify if running vulnerable software

Check Version:

Check device management interface or vendor documentation for version query commands

Verify Fix Applied:

Verify patch installation and confirm version matches patched release from vendor

📡 Detection & Monitoring

Log Indicators:

  • Multiple authentication attempts followed by service disruption events
  • Device restart logs after network activity

Network Indicators:

  • Unusual traffic patterns to Bizerba device management interfaces
  • Traffic spikes preceding service outages

SIEM Query:

source="bizerba_device" AND (event_type="service_stop" OR event_type="restart") AND src_ip IN [suspicious_ips]
