CODESYS Control V3 - Externally-controlled format string in Auditlog
Risk evaluation
The CODESYS Control runtime system's CmpAuditLog component allows potentially unauthenticated remote attackers to control the format string of processed log messages. Due to the internal processing logic, the impact is limited to a crash of the CODESYS Control runtime.
Mitigation summary
As a mitigation, the Audit Log feature can be disabled in the CODESYS Control runtime configuration file. When the Audit Log logger is not enabled, the affected functionality is no longer exposed and the vulnerability cannot be exploited. To disable the Audit Log feature, use the following settings. Depending on your existing configuration, the logger index may vary. [CmpLog] Logger.0.Name=.Audit.log Logger.0.Enable=0
