Vulnerability details

OpenKM 6.3.12 contains a remote code execution vulnerability that allows authenticated administrators to execute arbitrary Java/BeanShell code through the /admin/Scripting endpoint. Attackers can submit malicious script content with an action=Evaluate parameter to execute operating system commands in the context of…

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059 Command and Scripting Interpreter Execution
Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.
Why these techniques?

CWE-94 code injection in web app admin scripting endpoint directly enables server-side RCE via arbitrary script/command execution (T1059) after exploiting the public-facing application (T1190).

addresses: CWE-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

addresses: CWE-94

Validates inputs used in dynamic code generation to block injected directives.

addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.
