CVE-2019-11601
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 directory traversal vulnerability in remote access to backup & restore in earlier versions than ProSyst mBS SDK 8.2.6 and Bosch IoT Gateway Software 9.2.0 allows remote attackers to write or delete files at any location.
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 · moderate confidenceA directory traversal vulnerability exists in the remote backup and restore functionality of ProSyst mBS SDK and Bosch IoT Gateway Software. Attackers can use '..' sequences in backup/restore requests to escape the intended directory and write or delete files at arbitrary locations on the filesystem, leading to potential system compromise or 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 installed Bosch IoT softwareLocate and identify any Bosch IoT Gateway Software or ProSyst mBS SDK installations on the system. Check for directories or services related to Bosch IoT Gateway or ProSyst mBS.Affected if Either product is installed on the system
-
Determine installed software versionCheck the version of the installed Bosch IoT Gateway Software or ProSyst mBS SDK using vendor-provided tools, configuration files, or system inventory. Compare the version number against the affected ranges: < 9.2.0 for Bosch IoT Gateway Software and < 8.2.6 for ProSyst mBS SDK.Affected if The installed version is below 9.2.0 for Bosch IoT Gateway Software or below 8.2.6 for ProSyst mBS SDK
-
Verify backup/restore functionality statusCheck whether the remote backup and restore functionality is enabled on the gateway. This may involve reviewing the gateway configuration, service settings, or administrative interfaces for backup/restore service status.Affected if The remote backup/restore feature is enabled and accessible
-
Assess network exposure of backup/restore interfaceReview network configuration, firewall rules, or access control lists to determine if the backup/restore interface is exposed to network access. Check for open ports or services related to backup/restore functionality.Affected if The backup/restore interface is reachable from the network without proper access restrictions
A system is affected if it runs an installed version of Bosch IoT Gateway Software below 9.2.0 or ProSyst mBS SDK below 8.2.6, and the remote backup/restore functionality is enabled and network-accessible.

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 data8.2.69.2.0
Upgrade ProSyst mBS SDK to version 8.2.6 or later, and Bosch IoT Gateway Software to version 9.2.0 or later. Additionally, restrict network access to backup/restore interfaces and implement strict input validation on file paths.
