Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 21.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly addresses the injection vulnerability by requiring validation of all HTTP request inputs to counter lax character filtering and prevent arbitrary code execution.

SI-2 Flaw Remediation good match

prevent

Mandates timely identification, reporting, and remediation of the specific flaw in jeecg boot versions 3.0.0-3.5.3 to eliminate the injection vulnerability.

SC-7 Boundary Protection partial match

preventdetect

Boundary protection at external interfaces can monitor and block specially crafted HTTP requests that exploit the injection flaw before they reach vulnerable components.

Why these techniques?

CVE-2024-40489 is a critical unauthenticated remote code execution vulnerability in a public-facing web application (jeecg-boot) exploitable via crafted HTTP requests, directly mapping to T1190: Exploit Public-Facing Application.

Confidence: HIGH · MITRE ATT&CK Enterprise v19.0

NVD Description

There is an injection vulnerability in jeecg boot versions 3.0.0 to 3.5.3 due to lax character filtering, which allows attackers to execute arbitrary code on components through specially crafted HTTP requests.

Deeper analysisAI

CVE-2024-40489 is an injection vulnerability (CWE-94) in jeecg boot versions 3.0.0 through 3.5.3, caused by lax character filtering. This flaw allows attackers to execute arbitrary code on affected components through specially crafted HTTP requests. The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), marking it as critical due to its high impact on confidentiality, integrity, and availability.

Any unauthenticated attacker with network access can exploit this vulnerability, as it requires low attack complexity and no user interaction or privileges. Exploitation involves sending malicious HTTP requests that bypass filtering, leading to remote arbitrary code execution on the targeted jeecg boot instance.
