CWE-183: Permissive List of Allowed Inputs
Weakness Summary
The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are explicitly allowed by policy because the inputs are assumed to be safe, but the list is too permissive - that is, it allows an input that is unsafe, leading to resultant weaknesses.
- Canonical source: MITRE CWE-183 (opens in a new tab)
- Published Atomicorp CVE observations: 2
- Distinct affected products in those observations: 2
- Active Atomicorp rules associated with this weakness: 20
Atomicorp Research Context
Atomicorp has published CVE-specific research observations associated with this weakness category. Each linked CVE page states whether the tested request was detected or blocked and is the authoritative customer-facing finding.
The CVEs and rules shown here are selected published examples, not a complete list of Atomicorp protections. If a CWE, CVE, or rule is absent from this page, no conclusion should be drawn about whether Atomicorp protects against that weakness or attack method.
A CWE describes a class of software weakness. It does not identify one exploit request, and association with a CWE does not mean that every vulnerability or exploitation path in that category is detected or blocked.
