CVE-2026-97181 Overview
CVE-2026-97181 is a Sensitive Data Exposure vulnerability in GPM LIGHT developed by ezGlobal. Unauthenticated remote attackers can directly access system logs over the network without providing credentials. The weakness is categorized under [CWE-497] (Exposure of Sensitive System Information to an Unauthorized Control Sphere). TWCERT published advisories describing the issue and coordinating disclosure with the vendor.
System logs frequently contain operational details, internal identifiers, error traces, and user activity. Attackers can harvest this data to profile the environment and plan follow-on attacks against GPM LIGHT deployments reachable from untrusted networks.
Critical Impact
Unauthenticated remote attackers can read GPM LIGHT system logs directly, exposing operational data that supports reconnaissance and targeted follow-on attacks.

Technical Details for CVE-2026-97181
Vulnerability Analysis
The vulnerability allows an unauthenticated remote actor to access system log data served by GPM LIGHT. Because the attack vector is network-based and requires neither authentication nor user interaction, exposure is limited only by network reachability of the application. The CWE-497 classification indicates that sensitive internal information is disclosed to actors outside the intended control sphere.
The confidentiality impact is partial: the issue discloses log contents but does not, by itself, grant write access or control over the system. Logs can nonetheless reveal file paths, usernames, software versions, session identifiers, and error diagnostics useful for crafting subsequent attacks. See the TWCERT Security Alert for vendor-coordinated details.
Root Cause
The root cause is missing access control on an endpoint or resource that exposes system logs. GPM LIGHT does not enforce authentication or authorization before returning log data to the requester. This maps directly to [CWE-497], where sensitive system information is reachable by an unauthorized sphere.
Attack Vector
An attacker sends a direct request to the log-serving resource on an exposed GPM LIGHT instance. No credentials, tokens, or user interaction are required. The attacker then collects the returned log content for analysis. See the TWCERT Security Notice for additional context.
No verified proof-of-concept code is published for this CVE. The exploitation path is conceptually a single unauthenticated HTTP-style request to the log resource exposed by the application.
Detection Methods for CVE-2026-97181
Indicators of Compromise
- Unauthenticated HTTP requests from external sources targeting log-related URIs or files on GPM LIGHT hosts
- Repeated access patterns to the same log endpoint from a single remote IP address
- Outbound responses from GPM LIGHT containing large volumes of log-formatted text to untrusted clients
Detection Strategies
- Review web server and application access logs for requests to log-serving paths that return HTTP 200 without an authenticated session
- Correlate requests to GPM LIGHT with user-agent strings associated with scanners and automated reconnaissance tooling
- Baseline normal administrative access to log endpoints and alert on deviations from source IP, time of day, or request volume
Monitoring Recommendations
- Enable verbose access logging on any reverse proxy or web server fronting GPM LIGHT
- Forward application and proxy logs to a centralized analytics platform for retention and correlation
- Alert on anonymous access to any resource path containing log, logs, or similar substrings
How to Mitigate CVE-2026-97181
Immediate Actions Required
- Restrict network access to GPM LIGHT management and log endpoints using firewall rules or allowlists
- Place GPM LIGHT behind a reverse proxy that enforces authentication before any log resource is served
- Audit existing logs for prior unauthorized access to the exposed resource and rotate any credentials observed within log contents
Patch Information
Consult the TWCERT Security Alert and the TWCERT Security Notice for vendor-supplied remediation guidance. Apply any fixed version released by ezGlobal for GPM LIGHT as soon as it becomes available for your deployment.
Workarounds
- Block external access to the GPM LIGHT application at the perimeter until a vendor patch is applied
- Require VPN or zero-trust network access for any administrator interacting with GPM LIGHT
- Remove or relocate log files from any directory served directly by the application's web interface
