CVE-2024-48989

7.5 HIGH

📋 TL;DR

A vulnerability in the PROFINET stack implementation of Bosch Rexroth IndraDrive allows attackers to cause denial of service by sending arbitrary UDP messages, rendering affected devices unresponsive. This affects all versions of IndraDrive industrial drives used in automation systems.

💻 Affected Systems

Products:
  • Bosch Rexroth IndraDrive
Versions: All versions
Operating Systems: Embedded firmware
Default Config Vulnerable: ⚠️ Yes
Notes: Affects devices with PROFINET functionality enabled. Industrial control systems using these drives in manufacturing, automation, and critical infrastructure are at risk.

⚠️ 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 device unresponsiveness leading to production line stoppage, equipment damage, and safety hazards in industrial environments.

🟠

Likely Case

Temporary device unavailability requiring manual restart, causing production delays and operational disruption.

🟢

If Mitigated

Minimal impact with proper network segmentation and monitoring allowing quick detection and response.

🌐 Internet-Facing: HIGH if devices are directly exposed to internet, as exploit requires only UDP packet transmission.
🏢 Internal Only: MEDIUM to HIGH depending on network segmentation and attacker access to industrial network segments.

🎯 Exploit Status

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

Exploitation requires network access to PROFINET port (UDP). No authentication needed. Attack can be performed with simple UDP packet crafting tools.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Contact Bosch Rexroth for specific firmware updates

Vendor Advisory: https://psirt.bosch.com/security-advisories/BOSCH-SA-315415.html

Restart Required: Yes

Instructions:

1. Contact Bosch Rexroth support for firmware updates. 2. Schedule maintenance window. 3. Backup configuration. 4. Apply firmware update following vendor instructions. 5. Verify functionality after restart.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate PROFINET network from other networks using firewalls or VLANs

Port Filtering

all

Block unnecessary UDP traffic to PROFINET ports from untrusted networks

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate industrial control systems
  • Deploy intrusion detection systems monitoring for abnormal UDP traffic patterns

🔍 How to Verify

Check if Vulnerable:

Check device model and firmware version against Bosch advisory. Devices with PROFINET enabled are vulnerable.

Check Version:

Check via IndraDrive commissioning software or HMI interface (vendor-specific commands)

Verify Fix Applied:

Verify firmware version has been updated to version provided by Bosch Rexroth support.

📡 Detection & Monitoring

Log Indicators:

  • Device restart logs
  • PROFINET communication errors
  • Unexpected UDP traffic spikes

Network Indicators:

  • High volume of UDP packets to PROFINET ports (typically 34962-34964)
  • Malformed PROFINET packets

SIEM Query:

source_port:34962-34964 AND protocol:UDP AND (packet_size:anomalous OR rate_threshold_exceeded)
