Vulnerability details

JimuReport versions 2.3.4 and below are vulnerable to remote code execution due to improper handling of Aviator expressions. The /jmreport/executeSelectApi endpoint passes user-supplied input directly to the Aviator expression engine without adequate validation allowing attackers to execute arbitrary code.

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.
Why these techniques?

RCE via unauthenticated exploitation of public web endpoint /jmreport/executeSelectApi matches T1190 directly; no specific T1059 sub-technique is indicated by the Aviator expression injection.

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.
