What is CVE-2026-1023?
CVE-2026-1023 is an authentication bypass in Statistics Database System. A flaw in the authentication or session-handling logic lets a remote attacker reach administrative functions without valid credentials. In several reported cases this leads directly to remote code execution. Vendor description: Statistics Database System developed by Gotac has a Missing Authentication vulnerability, allowing unauthenticated remote attackers to directly exploit a specific functionality to query database contents.
Why this CVE matters
Authentication bypass on a network appliance or admin console is a top-tier target. Once the attacker is past the login, every administrative endpoint becomes available, including the ones that change settings, upload firmware, or run shell commands.
For deployments of Statistics Database System 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:
- Statistics Database System: 0 <= 1.0.3
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 Statistics Database System'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-2026-1023
The fix is to upgrade Statistics Database System to version 1.0.4 or later.
Affected versions confirmed in the CVE record:
Statistics Database System≤ 1.0.3
Patch via the OS package manager (Linux)
<!-- enrich_agent_2:v1 -->
# 1. Update the package metadata.
sudo apt update # Debian / Ubuntu
sudo dnf check-update # RHEL / Rocky / AlmaLinux / Fedora
sudo zypper refresh # openSUSE
# 2. Pull the patched version `1.0.4` of Statistics Database System from Gotac.
sudo apt install --only-upgrade statistics-database-system
sudo dnf upgrade statistics-database-system
sudo zypper update statistics-database-system
# 3. Restart the affected service so the patched binary is the running binary.
sudo systemctl restart statistics-database-system || true
# 4. Verify the running version.
statistics-database-system --version
Verify the fix worked
<!-- enrich_agent_2:v1 -->
# 1. Confirm the running version matches the fixed-in version from the advisory.
# Cross-check against the vendor advisory: https://www.twcert.org.tw/tw/cp-132-10639-813ad-1.html
# 2. Re-scan with your vulnerability scanner. The scanner should no longer flag
# this CVE on the patched host.
# Example with Nmap NSE:
nmap -sV --script vuln <target-host>
# 3. Inspect the service / kernel logs for crash-loops or rollback events in
# the first hour after the upgrade.
journalctl -u <service-name> --since "1 hour ago"
dmesg --since "1 hour ago"
If you cannot patch immediately
Restrict access to the affected administrative interface to trusted internal networks. Disable the vulnerable component if the vendor documents that as an interim option. Patch immediately when feasible.
How to verify the fix worked
- After applying the patch, verify the running version in the product's admin UI or via the vendor-documented CLI command.
- Confirm the patched build matches the version listed in the vendor advisory.
- Run an authenticated vulnerability scan with a current signature set and confirm the scanner no longer flags CVE-2026-1023.
- Review logs for the entire pre-patch window for indicators of compromise listed in the vendor or CISA advisory.
- Confirm any network-layer mitigations that were applied as a stopgap have been reverted (or left in place intentionally) once the patch is verified.
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 Statistics Database System, 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-2026-1023 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-2026-1023?
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 Statistics Database System 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.
