CVE-2019-11897
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 Server-Side Request Forgery (SSRF) vulnerability in the backup & restore functionality in earlier versions than ProSyst mBS SDK 8.2.6 and Bosch IoT Gateway Software 9.3.0 allows a remote attacker to forge GET requests to arbitrary URLs. In addition, this could potentially allow an attacker to read sensitive zip files from the local server.
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 confidenceThis is a Server-Side Request Forgery (SSRF) vulnerability in the backup and restore functionality of ProSyst mBS SDK and Bosch IoT Gateway Software. The vulnerability allows remote attackers to force the server to make GET requests to arbitrary URLs, potentially reaching internal systems. Additionally, the flaw permits reading sensitive zip files from the local server file system.

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 installed Bosch IoT Gateway Software versionLocate the installation directory and check the version file or banner. Common locations include /opt/bosch/iot-gateway or the installation root. Look for a version.info, VERSION, or similar file, or run: java -jar gateway.jar --versionAffected if The installed version is below 9.3.0
-
Identify installed ProSyst mBS SDK versionCheck the SDK installation directory for version information. Look in the SDK root folder for a version manifest or about file. The version is typically stored in a manifest.mf or version.properties file within the SDK librariesAffected if The installed version is below 8.2.6
-
Verify if backup/restore functionality is exposedExamine the web service configuration or API endpoints. Check configuration files (typically in a config/ or conf/ directory) for backup/restore service definitions. Look for endpoints related to backup, restore, or archive operations that may be accessible over HTTP/HTTPSAffected if The backup/restore interface is externally accessible without authentication or proper network restrictions
-
Inspect network logs for suspicious outbound requestsReview gateway or firewall logs for outgoing HTTP/HTTPS connections from the gateway server to unusual internal or external IP addresses. Focus on GET requests originating from the gateway software process, especially to internal IP ranges (127.0.0.0/8, 10.0.0.0/8, 192.168.0.0/16)Affected if Outbound GET requests are observed from the gateway to arbitrary URLs that were not initiated by legitimate backup operations
-
Check file system for unauthorized zip file accessAudit server logs and access records for backup/restore operations accessing zip files outside the expected backup directory. Review application logs for file read operations on sensitive system directoriesAffected if Evidence exists of zip file reads from locations outside designated backup directories, particularly system or configuration directories
You are affected if either Bosch IoT Gateway Software below 9.3.0 or ProSyst mBS SDK below 8.2.6 is installed AND the backup/restore interface is accessible, as the SSRF flaw allows arbitrary URL requests and local file access.

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 data8.2.69.3.0
Upgrade to ProSyst mBS SDK 8.2.6 or later, or Bosch IoT Gateway Software 9.3.0 or later. If immediate patching is not possible, restrict network access to the backup/restore interfaces and monitor for suspicious outbound requests.
