What is CVE-2026-41125?

CVE-2026-41125 is a SQL injection flaw in blueplanet 100 NX3 M8. User input reaches a database query without proper parameterization, letting an attacker read, modify, or in some cases execute commands through stacked queries or out-of-band channels. Vendor description: A vulnerability has been identified in blueplanet 100 NX3 M8 (All versions), blueplanet 100 TL3 GEN2 (All versions), blueplanet 105 TL3 (All versions), blueplanet 105 TL3 GEN2 (All versions), blueplanet 110 TL3 (All versions), blueplanet 125 NX3 M11 (All versions), blueplanet 125 TL3 (All versions), blueplanet 125 TL3 GEN2 (All versions), blueplanet 137 TL3 (All versions), blueplanet 150 TL3 (All versions), blueplanet 150 TL3 GEN2 (All versions), blueplanet 155 TL3 (All versions), blueplanet 155 TL3 GEN2 (All versions), blueplanet 165 TL3 (All versions), blueplanet 165 TL3 GEN2 (All versions), blueplanet 25.0 NX3-33.0 NX3 (All versions), blueplanet 3.0 NX3-20.0 NX3 (All versions), blueplanet 3.0-5.0 NX1 (All versions), blueplanet 360 NX3 M6 (All versions), blueplanet 50.0 NX3-60.0 NX3 (All versions), blueplanet 87.0 TL3 (All versions), blueplanet 87.0 TL3 GEN2 (All versions), blueplanet 92.0 TL3 (All versions), blueplanet 92.0 TL3 GEN2 (All versions), blueplanet gridsafe 110 TL3-S (All versions), blueplanet gridsafe 137 TL3-S (All versions), blueplanet gridsafe 92.0 TL3-S (All versions), blueplanet hybrid 10.0 TL3 (All versions), blueplanet hybrid 6.0 NH3-12.0 NH3 (All versions). Improper neutralization of special elements used in an sql command ('sql injection') in KACO Meteor server allows an authorized attacker to elevate privileges over a local network.

Why this CVE matters

SQL injection against a management product is rarely just a data leak. Once an attacker can read or write to the application database, the chain commonly ends with credential theft, persistence via scheduled tasks, or stacked queries that pivot into the operating system.

For deployments of blueplanet 100 NX3 M8 that have been exposed to the public internet during the disclosure window, the operating assumption should be that scanning has already happened. Even where exploitation has not been publicly observed, scanning for the vulnerable fingerprint is cheap and routine. Patching closes the door; log review and credential rotation close out the rest of the response.

Am I affected?

You are affected if your installation matches any of these version ranges:

Check your installed version against the list above. If you cannot determine the version, treat the system as affected and follow the upgrade path below.

Open blueplanet 100 NX3 M8's About dialog or run the vendor-documented version-check command. Compare the result against the affected ranges in the advisory.

How to fix CVE-2026-41125

  1. Read the vendor advisory in full: https://cert-portal.siemens.com/productcert/html/ssa-545643.html
  2. Upgrade blueplanet 100 NX3 M8 to 0, 0, 0, 0, 0, 0, 0 or a later version listed in the vendor advisory.
  3. Back up the configuration (and database, where applicable) before upgrading.
  4. Rotate any credentials, API keys, or session tokens that the vulnerable service touched. An unauthenticated RCE-class flaw means anything the process could see should be treated as exposed.
  5. Apply the patch in a maintenance window. For HA pairs, upgrade the standby node first, fail over, then upgrade the former primary.
  6. Restart the affected service so the patched binary loads, then verify the new version (see verification section).

# CVE-2026-41125 affects blueplanet 100 NX3 M8 0 < *.
# Fixed in *. Vendor advisory: https://cert-portal.siemens.com/productcert/html/ssa-545643.html

# 1. Identify the running version using the vendor-documented command.
#    (Open the product UI -> About, or run the CLI version probe.)

# 2. Stage the patched build named in the advisory.
#    Vendor advisory: https://cert-portal.siemens.com/productcert/html/ssa-545643.html

# 3. Apply the upgrade. If the vendor ships a Linux package, pull it via your
#    distribution's package manager:
sudo apt update && sudo apt install --only-upgrade blueplanet-100-nx3-m8        # Debian / Ubuntu
sudo dnf upgrade blueplanet-100-nx3-m8                                          # RHEL / Rocky / Alma / Fedora

# 4. Restart the affected service so the new binary loads.
sudo systemctl restart blueplanet-100-nx3-m8 2>/dev/null || true

# 5. Re-run the version probe and confirm it matches *.

# CVE-2026-41125 verification checklist.

# 1. Confirm the running version matches * (replace the version probe with
#    the platform-specific command shown above).

# 2. Re-scan the host with your vulnerability scanner (Nessus, Qualys, Tenable,
#    OpenVAS, Wazuh). The scanner must no longer flag CVE-2026-41125.

# 3. Inspect recent service and kernel logs for crash-loops or rollback events.
journalctl -u <service-name> --since "10 minutes ago"
dmesg --since "10 minutes ago"

# 4. Cross-check the running build against the vendor advisory:
#    https://cert-portal.siemens.com/productcert/html/ssa-545643.html

If you cannot patch immediately

Front the affected endpoint with a WAF rule that blocks SQL metacharacters in the vulnerable parameters. This is a stopgap, not a fix. Patch promptly.

How to verify the fix worked

If your installation was internet-reachable during the disclosure window, treat log review as part of the remediation rather than an optional follow-up. Look for unexpected administrator accounts in blueplanet 100 NX3 M8, scheduled tasks or cron jobs you did not create, new files in web-accessible directories, and outbound connections to addresses not in your baseline. Suspicious requests to the vulnerable endpoint immediately followed by successful 200-class responses with unusually large bodies are a strong indicator of exploitation.

Frequently asked questions

Is CVE-2026-41125 being exploited in the wild?

Public exploitation has not been confirmed by CISA at the time of writing. Treat the patch as time-sensitive anyway; reports often lag actual abuse.

Will a WAF or IDS rule fully mitigate CVE-2026-41125?

No. Network-layer filters can reduce noise and slow opportunistic scanners, but they will not stop a determined attacker. The vendor patch is the only durable fix.

Do I need to assume compromise if my blueplanet 100 NX3 M8 was internet-facing and unpatched?

For an unauthenticated RCE-class flaw exposed to the public internet during the known exploitation window, yes. Review logs, rotate credentials the process could access, and look for unexpected accounts, scheduled tasks, or outbound connections.
