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.

An exploitable heap overflow vulnerability exists in the WkbProgramLow function of WibuKey Network server management, version 6.40.2402.500. A specially crafted TCP packet can cause a heap overflow, potentially leading to remote code execution. An attacker can send a malformed TCP packet to trigger this vulnerability.

An exploitable pool corruption vulnerability exists in the 0x8200E804 IOCTL handler functionality of WIBU-SYSTEMS WibuKey.sys Version 6.40 (Build 2400). A specially crafted IRP request can cause a buffer overflow, resulting in kernel memory corruption and, potentially, privilege escalation. An attacker can send an IRP request to trigger this vulnerability.

An exploitable kernel memory disclosure vulnerability exists in the 0x8200E804 IOCTL handler functionality of WIBU-SYSTEMS WibuKey.sys Version 6.40 (Build 2400).A specially crafted IRP request can cause the driver to return uninitialized memory, resulting in kernel memory disclosure. An attacker can send an IRP request to trigger this vulnerability.

Cross-site scripting (XSS) vulnerability in the "advanced settings - time server" module in Wibu-Systems CodeMeter before 6.50b allows remote attackers to inject arbitrary web script or HTML via the "server name" field in actions/ChangeConfiguration.html.

Wibu-Systems CodeMeter Runtime before 5.20 uses weak permissions (read and write access for all users) for codemeter.exe, which allows local users to gain privileges via a Trojan horse file.

Wibu-Systems AG CodeMeter Runtime 4.30c, 4.10b, and possibly other versions before 4.40 allows remote attackers to cause a denial of service (CodeMeter.exe crash) via certain crafted packets to TCP port 22350.

Cross-site scripting (XSS) vulnerability in Licenses.html in Wibu-Systems CodeMeter WebAdmin 3.30 and 4.30 allows remote attackers to inject arbitrary web script or HTML via the BoxSerial parameter.
