High 7.0
Out of Bound Write on WibuKey for Windows
In the WibuKey driver for Windows below Version 6.72, insufficient validation of user input when calculating the size of a kernel buffer could cause small amounts of data to be written outside the intended kernel buffer. This can lead to a system crash. Under…

High 8.8
User input in WibuKey is used (without proper sanitization) to compute the address of a pointer, which can be exploited to let the user point to any storage, to which Windows responds with a denial of service.
Improper validation of memory boundaries in WibuKey64.sys of WibuKey up to 6.70 for Windows can be exploited by an attacker by setting the pointers outside the scope of the program. This usually results in a denial of service, yet we cannot rule out the possi…

An untrusted Pointer Dereference can be exploited to escalate privileges by an unprivileged user on Windows
In WibuKey for Windows before version 6.71, an untrusted pointer dereference in the WibuKey2_64.sys kernel driver for 64-bit Windows allows an attacker to exploit a write-what-where primitive, enabling local privilege escalation. This can be leveraged to exec…

High 7.7
Improper Authentication of Session Handles
If configured as a server, CodeMeter Runtime before versions 8.41a and 9.10 issues handles per connection and relies on a cryptographically weak SID as sole authenticator. An attacker can brute-force the SID, recover another session's handle number, and read …

High 7.5
Missing Sanity Checks for Buffer Lengths
If configured as a server, CodeMeter Runtime before versions 8.41a and 9.10 accepts requests with opcode 0x5e, which contain the data length and the data itself. Missing bounds checking on the data length value can lead to out of bounds reads, causing a segme…

High 8.2
Format String Vulnerability in Logger
In CodeMeter Runtime before versions 8.41a and 9.10, the logger does not sanitize input strings in certain cases, allowing an attacker to inject printf-style format specifiers. This can be used to reliably crash CodeMeter and disclose sensitive information su…

High 8.6
Improper Access Control in Local-Only Configuration Commands
If CodeMeter Runtime before 8.41a or 9.10 is configured as a server, the configuration command handler does not enforce network- origin restrictions. Commands intended only for local or same-network clients can therefore be executed by arbitrary remote peers.…

Local Privilege Escalation in CodeMeter Runtime on Windows
In CodeMeter Runtime from version 8.40 to (excluding) 8.41a and 9.00 to (excluding) 9.10, cmu.exe --create-io --file C: creates a predictable temporary file under C:\CM-Stick. The directory and file paths are not properly checked for NTFS reparse points, such…

CodeMeter 6.60 - 'CodeMeter.exe' Unquoted Service Path
CodeMeter 6.60 contains an unquoted service path vulnerability that allows local users to potentially execute arbitrary code with elevated system privileges. Attackers can exploit the unquoted binary path in the CodeMeter Runtime Server service to inject mali…

High 7.8
WibuKey Runtime 6.51 - 'WkSvW32.exe' Unquoted Service Path
WibuKey Runtime 6.51 contains an unquoted service path vulnerability in the WkSvW32.exe service that allows local attackers to potentially execute arbitrary code. Attackers can exploit the unquoted path in 'C:\PROGRAM FILES (X86)\WIBUKEY\SERVER\WkSvW32.exe' t…
