Vulnerabilities in Wibu Systems CodeMeter Runtime Affect Multiple SICK Products

Several vulnerabilities in the Wibu Systems CodeMeter Runtime affect the SICK products Sentio Creator, Sentio Compose, Safety Designer, Stream Editor, CODE-LOC, LiDAR-LOC, PLB, SIM1200-2A1A130 LiDAR-LOC and multiple SICK Industrial PCs APU0G00, APU0G50, APU0G03, APU3F00, APU4600, APU8G00 and...

Vulnerabilities in Wibu-Systems’ CodeMeter Runtime

Wibu-Systems has addressed several vulnerabilities in CodeMeter Runtime. These vulnerabilities are located in various components of CodeMeter Runtime, particularly in versions 8.41a and 9.10. A local attacker can exploit incorrect verification of NTFS reparse points when creating temporary files...

CVE-2026-81574

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 canarie...

CVE-2026-81575

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...

CVE-2026-81576

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 anoth...

CVE-2026-81573

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...

CVE-2026-81572

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 fi...

CVE-2026-81576 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 license information belonging to anoth...

CVE-2026-81576 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 license information belonging to anoth...

EUVD-2026-66983

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 anoth...

CVE-2026-81576

CodeMeter Runtime (WIBU), when configured as a server in versions before 8.41a and 9.10 , issues a per-connection session handle and relies on a cryptographically weak SID as the sole authenticator. An attacker with network access can brute-force the SID , recover another session's handle number,...

EUVD-2026-66982

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...

CVE-2026-81575 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 segmentation fault that ultimately crashes...

CVE-2026-81575 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 segmentation fault that ultimately crashes...

CVE-2026-81575

CodeMeter Runtime (WIBU) prior to versions 8.41a and 9.10 is vulnerable when configured as a server. Requests carrying opcode 0x5e include a data-length field that lacks bounds checking, allowing an attacker to trigger out-of-bounds reads that result in a segmentation fault and crash the Runtime....

CVE-2026-81574 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 such as process memory and stack canarie...

EUVD-2026-66981

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 canarie...
