CVE-2023-39509

7.2 HIGH

📋 TL;DR

This CVE describes a command injection vulnerability in Bosch IP cameras that allows authenticated administrators to execute arbitrary operating system commands on the camera device. This affects organizations using vulnerable Bosch IP camera models, potentially allowing attackers with administrative credentials to take full control of affected cameras.

💻 Affected Systems

Products:
  • Bosch IP cameras
Versions: Specific versions not detailed in provided references; consult Bosch advisory for exact affected versions
Operating Systems: Embedded Linux-based camera firmware
Default Config Vulnerable: ⚠️ Yes
Notes: Requires administrative authentication; affects cameras with web interface access enabled

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of camera system allowing persistent access, lateral movement to other network devices, data exfiltration, and use as pivot point for further attacks.

🟠

Likely Case

Unauthorized access to camera feeds, modification of camera settings, installation of malware, and disruption of surveillance operations.

🟢

If Mitigated

Limited impact if proper network segmentation, strong authentication, and least privilege principles are implemented.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Exploitation requires administrative credentials; command injection typically involves manipulating web interface parameters

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Bosch security advisory for specific firmware versions

Vendor Advisory: https://psirt.bosch.com/security-advisories/BOSCH-SA-638184-BT.html

Restart Required: Yes

Instructions:

1. Identify affected camera models and current firmware versions. 2. Download updated firmware from Bosch support portal. 3. Follow Bosch firmware update procedures for your specific camera model. 4. Verify successful update and functionality.

🔧 Temporary Workarounds

Network segmentation

all

Isolate cameras on separate VLAN with restricted access

Access control hardening

all

Implement strong authentication and limit administrative access

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate cameras from critical systems
  • Enforce strong authentication policies and regularly rotate administrative credentials

🔍 How to Verify

Check if Vulnerable:

Check camera firmware version against Bosch advisory; cameras with vulnerable firmware versions are affected

Check Version:

Check via camera web interface: System > Information > Firmware Version

Verify Fix Applied:

Verify firmware version has been updated to patched version specified in Bosch advisory

📡 Detection & Monitoring

Log Indicators:

  • Unusual command execution patterns in system logs
  • Multiple failed authentication attempts followed by successful admin login
  • Unexpected system configuration changes

Network Indicators:

  • Unusual outbound connections from camera devices
  • Traffic patterns inconsistent with normal camera operation
  • Command and control traffic from camera IPs

SIEM Query:

source="camera_logs" AND (event="command_execution" OR event="system_config_change") AND user="admin"
