WAGO: Vulnerable WIBU-SYSTEMS Codemeter installed through e!COCKPIT

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.

Multiple memory corruption vulnerabilities exist in CodeMeter (All versions prior to 7.10) where the packet parser mechanism does not verify length fields. An attacker could send specially crafted packets to exploit these vulnerabilities.

CodeMeter (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. Only CmActLicense update files with CmActLicense Firm Code are affected.

CodeMeter (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.

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. This is especially relevant for systems or devices where a web browser is used to access a web server) via a specifically crafted Java Script payload, which may allow alteration or creation of license files for when combined with CVE-2020-14515.

An attacker could send a specially crafted packet that could have CodeMeter (All versions prior to 7.10) send back packets containing data from the heap.
