CVE-2020-6776
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability in the web-based management interface of Bosch PRAESIDEO until and including version 4.41 and Bosch PRAESENSA until and including version 1.10 allows an unauthenticated remote attacker to trigger actions on an affected system on behalf of another user (Cross-Site Request Forgery). This requires the victim to be tricked into clicking a malicious link or submitting a malicious form. A successful exploit allows the attacker to perform arbitrary actions with the privileges of the victim, e.g. creating and modifying user accounts, changing system configuration settings and cause DoS conditions. Note: For Bosch PRAESIDEO 4.31 and newer and Bosch PRAESENSA in all versions, the confidentiality impact is considered low because user credentials are not shown in the web interface.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceCross-Site Request Forgery (CSRF) vulnerability in the web-based management interfaces of Bosch PRAESIDEO (versions up to 4.41) and Bosch PRAESENSA (versions up to 1.10) allows unauthenticated remote attackers to trick authenticated users into performing unintended actions such as creating/modifying user accounts, changing system configuration, or causing denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Bosch PRAESIDEO or PRAESENSA is deployedReview asset inventory or network scans for devices running PRAESIDEO or PRAESENSA firmware. Check device labels, management console, or consult documentation for the installed system.Affected if Bosch PRAESIDEO or PRAESENSA systems are found in the environment
-
Determine the installed firmware versionLog into the web-based management interface and navigate to the system information or status page to view the firmware version. Alternatively, check via the admin desktop application if available.Affected if Firmware version is 4.41 or lower for PRAESIDEO, or 1.10 or lower for PRAESENSA
-
Verify the web management interface is accessibleAttempt to access the PRAESIDEO or PRAESENSA web interface URL (typically HTTPS on ports 443 or 8443) from a browser or curl command to confirm it responds.Affected if The web-based management interface is reachable and responds to HTTP/HTTPS requests
-
Check if the web interface is exposed to untrusted networksReview firewall rules, NAT configurations, or access control lists to determine if the management web interface is accessible from outside the local network or from the internet.Affected if The web interface is accessible from untrusted networks or the internet without VPN or network segmentation
A user is affected if they have Bosch PRAESIDEO firmware <= 4.41 or PRAESENSA firmware <= 1.10 with the web-based management interface accessible to potential attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement anti-CSRF tokens (synchronizer token pattern) on all state-changing forms and validate tokens server-side; additionally, verify Origin/Referer headers as a defense-in-depth measure. Until patch is available, restrict web interface access via network segmentation or VPN.
