CVE-2022-45094
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, could potentially inject commands into the dhcpd configuration of the affected product. 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 confidenceCommand injection vulnerability in SINEC INS web-based management interface (443/tcp). An authenticated attacker can inject malicious commands into the dhcpd configuration file, potentially achieving remote code execution on the affected component.

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 if SINEC INS is installedLocate SINEC INS installation directories or check for the web-based management service running on port 443/tcp using netstat or similar network scanning toolsAffected if SINEC INS is present and the web interface is accessible on port 443/tcp
-
Determine installed SINEC INS versionConsult the SINEC INS documentation or check the software version through the web management interface, typically found in the About or System Information sectionAffected if The installed version is any version prior to 1.0, or exactly version 1.0 (the affected versions)
-
Verify DHCP configuration feature accessibilityLog into the SINEC INS web interface and navigate to the DHCP server configuration section to determine if this feature is accessible to authenticated usersAffected if The DHCP configuration functionality is enabled and accessible to authenticated users
-
Inspect DHCP configuration file for anomaliesAccess and review the dhcpd.conf or equivalent DHCP configuration file used by SINEC INS, looking for unexpected commands, scripts, or suspicious entries that do not belong to your intended DHCP configurationAffected if The DHCP configuration file contains unexpected or malicious command entries that were not intentionally configured by the administrator
-
Review system logs for command injection indicatorsCheck SINEC INS and underlying system logs for authentication events followed by DHCP configuration changes, particularly entries indicating shell command execution or privilege escalationAffected if Logs show DHCP configuration changes accompanied by evidence of command execution or unauthorized system modifications
A user is affected if SINEC INS version 1.0 or earlier is installed, the web interface on port 443/tcp is accessible, and the DHCP configuration feature is enabled and could accept malicious input.

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. If immediate patching is not feasible, restrict network access to the web-based management interface and monitor for suspicious DHCP configuration changes.
SINEC INS V1.0 SP2 Update 1
- Upgrade SINEC INS to version V1.0 SP2 Update 1 or later to remediate the command injection vulnerability.
- Verify the upgrade by confirming the new version through the Web Based Management interface.
- Test that the DHCP configuration functionality works correctly after the upgrade.
- Ensure the attacker no longer can inject commands into the dhcpd configuration through the Web Based Management interface.
