Security readout for executives and security teams
Plain-English summary
Some Bosch IP cameras can be reached remotely without required authentication, allowing sensitive information extraction or settings changes. The issue is critical because exploitation requires no login or user interaction, but the provided sources do not show confirmed active exploitation.
Executive priority
Treat as urgent for internet-exposed or broadly reachable Bosch camera fleets. The business risk is unauthorized access to camera information and settings, potentially affecting surveillance integrity and operational trust.
Technical view
CVE-2021-23847 is CWE-287 missing authentication in a critical function. Crafted remote requests can bypass expected authentication on affected Bosch CPP6, CPP7, and CPP7.3 camera firmware, with CVSS 3.1 score 9.8 and high confidentiality, integrity, and availability impact.
Likely exposure
Organizations operating Bosch IP cameras in CPP6, CPP7, or CPP7.3 families on firmware 7.70, 7.72, or 7.80 before B128. Bosch states versions 7.62 or lower and INTEOX cameras are not affected.
Exploitation context
The source bundle marks CISA KEV status as false and provides no cited evidence of active exploitation. Risk remains high because the attack is remote, unauthenticated, low complexity, and can affect device confidentiality and configuration integrity.
Researcher notes
Evidence is limited to CVE and Bosch advisory material in the bundle. Do not broaden scope beyond CPP6, CPP7, and CPP7.3 firmware 7.70, 7.72, and 7.80 before B128 without vendor confirmation.
Mitigation direction
- Identify Bosch IP cameras and firmware versions across production networks.
- Upgrade affected CPP6, CPP7, and CPP7.3 firmware to B128 or later where available.
- Review Bosch PSIRT guidance before applying operational changes.
- Restrict camera management access to trusted administrative networks.
- Monitor camera configuration changes and unexpected remote access attempts.
Validation and detection
- Confirm each Bosch camera family: CPP6, CPP7, CPP7.3, INTEOX, or other.
- Record firmware versions and flag 7.70, 7.72, and 7.80 before B128.
- Verify cameras on 7.62 or lower are not within the affected set described by Bosch.
- Check whether affected cameras are reachable from untrusted networks.
- Review recent configuration changes for unauthorized modifications.

Improper Authentication
Improper Authentication represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
