According to its self-reported version, the CodeMeter WebAdmin server installed on the remote host is prior to 6.90. It is affected by an issue in the license-file signature checking mechanism, which allows attackers to build arbitrary license files, including forging a valid license file as if it were a valid license file of an existing vendor. Only CmActLicense Update Files with CmActLicense Firm Codes are affected.
