Description

XML external entity (XXE) injection in eyoucms v1.7.1 allows remote attackers to cause a denial of service via crafted body of a POST request.

Mitigating Controls (NIST 800-53 r5)AI

prevent

SI-10 requires validation of information inputs, directly preventing XXE injection by rejecting or sanitizing crafted XML payloads in POST requests.

preventdetect

SC-5 protects against denial-of-service events like resource exhaustion from XXE entity expansion attacks.
