CVE-2022-45093
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 has been identified in SINEC INS (All versions < V1.0 SP2 Update 1). An authenticated remote attacker with access to the Web Based Management (443/tcp) of the affected product as well as with access to the SFTP server of the affected product (22/tcp), could potentially read and write arbitrary files from and to the device's file system. An attacker might leverage this to trigger remote code execution on the affected component.
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 confidenceAn authenticated file read/write vulnerability in SINEC INS allows attackers with credentials to both the Web Based Management (443/tcp) and SFTP server (22/tcp) to read and write arbitrary files to the device's file system. This file operation primitive can be leveraged for remote code execution by writing malicious content to web-accessible directories or modifying system configurations.

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 SINEC INS installation and versionLocate SINEC INS in your system inventory or installed software list, and note the exact version number installed. Compare this version against the affected range: versions < 1.0 and = 1.0 are vulnerable.Affected if The installed version is 1.0 or any version below 1.0.
-
Verify Web Based Management port 443 is accessibleCheck if TCP port 443 is open and accepting connections on the device hosting SINEC INS. Use a network scan or check firewall rules to confirm exposure.Affected if Port 443 is reachable from an untrusted network and SINEC INS version is 1.0 or below.
-
Verify SFTP server port 22 is accessibleCheck if TCP port 22 is open and accepting connections on the device hosting SINEC INS. Use a network scan or check firewall rules to confirm exposure.Affected if Port 22 is reachable from an untrusted network and SINEC INS version is 1.0 or below.
-
Confirm authentication credentials exist for affected servicesDetermine whether valid credentials exist for the SINEC INS Web Based Management interface (port 443) and/or the SFTP server (port 22). This vulnerability requires valid authentication to exploit.Affected if Valid credentials are configured for either the WBM or SFTP service, and the SINEC INS version is 1.0 or below.
You are affected if SINEC INS version 1.0 or below is installed, the Web Based Management (443/tcp) or SFTP (22/tcp) interfaces are accessible, and valid credentials exist for these services.

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.
dbcve · scoped1.0
Upgrade SINEC INS to version V1.0 SP2 Update 1 or later. Until then, restrict network access to ports 443 and 22 to trusted personnel only, and enforce strong, unique credentials for both management interfaces.
V1.0 SP2 Update 1
- Obtain SINEC INS version V1.0 SP2 Update 1 (or later) from the official Siemens support portal
- Follow the standard SINEC INS upgrade procedure to apply the update
- Verify the upgrade was successful by checking the version number in the Web Based Management interface
