Security readout for executives and security teams
Plain-English summary
This flaw lets an unauthenticated remote attacker abuse backup/restore features in vulnerable Bosch/ProSyst gateway software to make the server request arbitrary URLs. The main business risk is confidential data exposure, including possible access to sensitive local zip files. Systems running versions before fixed releases should be treated as high-priority remediation targets.
Executive priority
Prioritize remediation for internet-facing or partner-facing gateway deployments first. The vulnerability can be exploited without authentication and primarily threatens confidentiality, which may include sensitive backup or local zip data. No active exploitation is cited, but the technical severity justifies prompt patch verification.
Technical view
CVE-2019-11897 is a CWE-918 SSRF in backup and restore functionality affecting ProSyst mBS SDK before 8.2.6 and Bosch IoT Gateway Software before 9.3.0. It is network exploitable, requires no privileges or user interaction, changes scope, and is rated CVSS 3.0 8.6 with high confidentiality impact.
Likely exposure
Exposure is most likely in deployments using Bosch IoT Gateway Software or products built on ProSyst mBS SDK where the vulnerable backup/restore interface is reachable over a network. The source bundle does not identify specific deployment defaults, CPEs, or all affected version ranges beyond versions earlier than the fixed releases.
Exploitation context
The provided sources do not report known active exploitation, and the CVE is not marked as CISA KEV. The vulnerability is still serious because the stated attack path is remote, unauthenticated, low complexity, and could expose sensitive files through server-side request forgery behavior.
Researcher notes
The public record establishes SSRF in backup/restore handling and possible local sensitive zip file exposure, but does not provide detailed vulnerable endpoints, deployment preconditions, or exhaustive affected version mapping. Treat exploit status as unconfirmed unless new vendor or KEV evidence appears.
Mitigation direction
- Upgrade ProSyst mBS SDK to 8.2.6 or later where applicable.
- Upgrade Bosch IoT Gateway Software to 9.3.0 or later where applicable.
- Check Bosch PSIRT guidance for product-specific remediation details.
- Restrict network access to backup and restore functionality until remediation is complete.
- Review whether downstream products embed the affected ProSyst mBS SDK.
Validation and detection
- Inventory Bosch IoT Gateway Software and ProSyst mBS SDK usage across environments.
- Confirm deployed versions are not earlier than the fixed releases.
- Verify backup and restore interfaces are not exposed to untrusted networks.
- Review logs for unusual backup/restore activity or unexpected outbound server requests.
- Check for sensitive zip files accessible on affected local servers.

Server-Side Request Forgery (SSRF)
Server-Side Request Forgery (SSRF) represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
