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.

Mitigating Controls (NIST 800-53 r5)AI

prevent

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

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.

preventdetect

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

Security SummaryAI

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.
