Vulnerabilidades

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 license information belonging to another handle.

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 segmentation fault that ultimately crashes the CodeMeter Runtime.

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 such as process memory and stack canaries. The attack works…

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. An attacker can read potentially sensitive configuration…

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 as junctions or symbolic links, before file operations are…

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 malicious code that would execute with LocalSystem permissions.

Wibu CodeMeter before 8.30a sometimes allows privilege escalation immediately after installation (before a logoff or reboot). For exploitation, there must have been an unprivileged installation with UAC, and the CodeMeter Control Center component must be installed, and the CodeMeter Control Center component must not…

A heap buffer overflow vulnerability in Wibu CodeMeter Runtime network service up to version 7.60b allows an unauthenticated, remote attacker to achieve RCE and gain full access of the host system.

In WIBU CodeMeter Runtime before 7.30a, creating a crafted CmDongles symbolic link will overwrite the linked file without checking permissions.

A denial of service vulnerability exists in Wibu-Systems CodeMeter versions < 7.21a. An unauthenticated remote attacker can exploit this issue to crash the CodeMeter Runtime Server.

A buffer over-read vulnerability exists in Wibu-Systems CodeMeter versions < 7.21a. An unauthenticated remote attacker can exploit this issue to disclose heap memory contents or crash the CodeMeter Runtime Server.

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.

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…

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.

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…

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.

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.

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.
