This updated advisory is a follow-up to the advisory update titled ICSA-20-203-01 Wibu-Systems CodeMeter (Update E) that was published February 11, 2021, to the ICS webpage on www.cisa.gov/uscert.
Successful exploitation of these vulnerabilities could allow an attacker to alter and forge a license file, cause a denial-of-service condition, potentially attain remote code execution, read heap data, and prevent normal operation of third-party software dependent on the CodeMeter.
The following versions of CodeMeter Runtime, a license manager, are affected:
This license manager is used in products by many different vendors. As new instances are discovered/reported, they will be added to this list of affected products.
Multiple memory corruption vulnerabilities exist where the packet parser mechanism does not verify length fields. An attacker could send specially crafted packets to exploit these vulnerabilities.
CVE-2020-14509 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
Protocol encryption can be easily broken and the server accepts external connections, which may allow an attacker to remotely communicate with the CodeMeter API.
CVE-2020-14517 has been assigned to this vulnerability. A CVSS v3 base score of 9.4 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H).
This vulnerability allows an attacker to use the internal WebSockets API via a specifically crafted Java Script payload, which may allow alteration or creation of license files when combined with CVE-2020-14515.
CVE-2020-14519 has been assigned to this vulnerability. A CVSS v3 base score of 8.1 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H).
CodeMeter and the software using it may crash while processing a specifically crafted license file due to unverified length fields.
CVE-2020-14513 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
There is 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.
CVE-2020-14515 has been assigned to this vulnerability. A CVSS v3 base score of 7.4 has been calculated; the CVSS vector string is (AV:L/AC:H/PR:N/UI:R/S:C/C:N/I:H/A:H).
An attacker could send a specially crafted packet that could have the server send back packets containing data from the heap.
CVE-2020-16233 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
