CVE-2023-22855
Published: 15 February 2023
Summary
CVE-2023-22855 is a critical-severity Code Injection (CWE-94) vulnerability in Kardex Kardex Control Center. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 1.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Kardex Mlog MCC version 5.7.12+0-a203c2a213-master contains a remote code execution vulnerability in its web interface, which listens on TCP port 8088. The flaw stems from insufficient sanitization of a user-supplied path before it is passed to .NET's Path.Combine method, allowing inclusion of arbitrary local files or remote files hosted on SMB shares. Files with a .t4 extension are subsequently processed by the mono/t4 templating engine, which permits arbitrary code execution and corresponds to CWE-94.
An unauthenticated attacker with network access can exploit the issue by crafting a request that references a malicious .t4 file, resulting in full compromise of the affected system with impacts on confidentiality, integrity, and availability. The vulnerability carries a CVSS 3.1 base score of 9.8, reflecting its critical severity and the absence of required authentication or user interaction.
Publicly available references, including detailed advisories and working exploits on Exploit-DB, Packet Storm, and GitHub, demonstrate reliable remote code execution but do not describe vendor patches or configuration mitigations.
EPSS scores for the CVE rose from lower values after disclosure to a peak of 0.8040 on 2025-01-22 before receding to the current 0.6157, indicating that exploitation interest increased substantially well after the initial publication date.

Vulnerability details
Kardex Mlog MCC 5.7.12+0-a203c2a213-master allows remote code execution. It spawns a web interface listening on port 8088. A user-controllable path is handed to a path-concatenation method (Path.Combine from .NET) without proper sanitisation. This yields the possibility of including local files,…

as well as remote files on SMB shares. If one provides a file with the extension .t4, it is rendered with the .NET templating engine mono/t4, which can execute code.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
