This vulnerability allows an attacker to use the internal WebSockets API for CodeMeter (All versions prior to 7.00 are affected, including Version 7.0 or newer with the affected WebSockets API still enabled. Protocol encryption can be easily broken for CodeMeter (All versions prior to 6.90 are affected, including Version 6.90 or newer only if CodeMeter Runtime is running as server) and the server accepts external connections, which may allow an attacker to remotely communicate with the CodeMeter API.ĬVSS v3.0 Base Score 8.1 | High | CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H Only CmActLicense update files with CmActLicense Firm Code are affected.ĬVSS v3.0 Base Score 7.5 | High | CVSS:3.0/ AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H An attacker could send specially crafted packets to exploit these vulnerabilities.ĬVSS v3.0 Base Score 7.5 | High | CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HĬodeMeter (All versions prior to 6.81) and the software using it may crash while processing a specifically crafted license file due to unverified length fields.ĬVSS v3.0 Base Score 7.4 | High | CVSS:3.0/AV:L/AC:H/PR:N/UI:R/S:C/C:N/I:H/A:HĬodeMeter (All versions prior to 6.90 when using CmActLicense update files with CmActLicense Firm Code) has 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. Multiple memory corruption vulnerabilities exist where the packet parser mechanism of CodeMeter (All versions prior to 7.10a) does not verify length fields. - Global Availability / Support / TrainingĬVSS v3.0 Base Score 10.0 | Critical | CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H.
