Logsign Unified SecOps Platform 認証バイパス脆弱性

The impact of this vulnerability is severe. An attacker can bypass authentication entirely, meaning no credentials are required to exploit it. This allows them to potentially access sensitive data, modify configurations, and execute arbitrary commands on the affected system. The lack of authentication requirements significantly broadens the attack surface and increases the risk of unauthorized access. Successful exploitation could lead to a complete compromise of the Logsign Unified SecOps Platform, impacting its ability to provide security monitoring and incident response capabilities. The vulnerability's ease of exploitation, coupled with the platform's security-critical role, makes it a high-priority concern.

Organizations heavily reliant on Logsign Unified SecOps Platform for security monitoring and incident response are at significant risk. Specifically, deployments with limited network segmentation or those lacking robust access controls are particularly vulnerable. Shared hosting environments utilizing Logsign are also at increased risk due to the potential for cross-tenant exploitation.

• linux / server: Monitor access logs for requests to the web service (TCP port 443) without authentication headers. Use journalctl -u logsign to search for authentication-related errors.

journalctl -u logsign | grep -i authentication

• generic web: Use curl to attempt accessing the platform's web interface without providing authentication credentials. Check the response headers for any indications of successful access without authentication.

curl -I https://<logsign_ip>/  # Check for 200 OK without auth

The primary mitigation for CVE-2025-1044 is to immediately upgrade to version 6.4.32 or later. If upgrading is not immediately feasible due to compatibility concerns or system downtime requirements, consider implementing temporary workarounds. While no direct WAF rules can prevent the bypass, strict network segmentation and limiting external access to the platform's web service (TCP port 443) can reduce the attack surface. Regularly review access logs for suspicious activity and implement multi-factor authentication where possible, though this does not directly address the bypass. After upgrading, confirm the vulnerability is resolved by attempting to access the platform without providing valid credentials; access should be denied.
