Security readout for executives and security teams
Plain-English summary
This flaw lets an unauthenticated remote attacker abuse backup and restore handling to write or delete files outside the intended directory. For affected Bosch IoT Gateway Software or ProSyst mBS SDK deployments, that can disrupt service or alter system files. The sources identify fixed version boundaries but do not show active exploitation.
Executive priority
Treat this as urgent for any exposed gateway or SDK-based product because the impact is file modification or deletion without authentication. Prioritize internet-facing and remotely managed deployments first.
Technical view
CVE-2019-11601 is a path traversal vulnerability in remote backup and restore access. Versions earlier than ProSyst mBS SDK 8.2.6 and Bosch IoT Gateway Software 9.2.0 are described as affected. CVSS 3.0 is 9.1 with network attack vector, low complexity, no privileges, no user interaction, and high integrity and availability impact.
Likely exposure
Exposure is most likely where Bosch IoT Gateway Software or products built with ProSyst mBS SDK expose remote backup and restore functionality. The provided data does not include CPEs, deployment prevalence, or internet-exposure evidence.
Exploitation context
The CVE is not listed as KEV in the provided bundle, and no cited source reports active exploitation. Risk remains high because the CVSS vector indicates remote, unauthenticated, low-complexity access with file write or delete impact.
Researcher notes
The affected-product metadata in the bundle is incomplete, but the description names the relevant Bosch products and fixed version thresholds. Avoid assuming broader Bosch product impact without vendor confirmation.
Mitigation direction
- Upgrade ProSyst mBS SDK to 8.2.6 or later where applicable.
- Upgrade Bosch IoT Gateway Software to 9.2.0 or later where applicable.
- Review Bosch PSIRT guidance for product-specific remediation details.
- Restrict access to backup and restore interfaces until remediation is confirmed.
Validation and detection
- Inventory deployments using Bosch IoT Gateway Software or ProSyst mBS SDK.
- Confirm installed versions are not earlier than the fixed versions.
- Identify whether remote backup and restore access is reachable from untrusted networks.
- Review vendor advisories and asset records for embedded SDK usage.
