Unauthorized access via default credentials
Published Sep 28, 2026 · Updated Sep 28, 2026
Use of default credentials in Logsign SIEM 6.4.101 through 6.4.116 allows remote attackers to access the service through its login interface. The public advisory text does not identify the affected account, credential pair, or authentication path that retains default values. Exploitation requires network access to the affected login service; the available record does not establish administrator privileges or specific post-login capabilities.
