common-exploit-verification skillA

This file is byte-identical to the first copy the registry indexed, one of 3 copies on public GitHub. Same content hash, same audit grade.

common-exploit-verification is agent-read markdown (skill) from hoangnguyen0403/agent-skills-standard: Enforce "No Exploit, No Report" policy with PoC construction standards, false-positive filtering, and evidence collection per vulnerability class across backend, frontend, and mobile. Use when validating security findings, constructing exploit proofs, filtering false positives, or writing pentest findings..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Exploit Verification Standard

## **Priority: P0 (CRITICAL)**

## Always-Apply Rules

- **No Exploit = No Report**: Finding without reproducible PoC is discarded. No exceptions.
- **No Theoretical Findings**: "This could be exploited if..." → rejected. Demonstrate actual impact.
- **No Tool Output as Evidence**: Scanner output alone insufficient. Manual verification required.

## PoC Construction

Every confirmed finding must include all fields:

```
ID: [unique identifier]
Vulnerability: [CWE-XXX: type name]
Platform: [backend|frontend|mobile-ios|mobile-android]
Component: [file:line or endpoint]
Severity: [Critical|High|Medium|Low] (CVSS: X.X)
OWASP: [mapping — e.g., A03:2021, API1:2023, M4:2024]

-- Proof of Concept --
Preconditions: [required state, auth level, config]
Steps:
1. [exact step with command/payload]
2. [expected vs actual result]
Payload: [exact input — copy-paste ready]
Evidence: [response body, status code, data returned]

-- Impact --
Impact: [what attacker gains — data, access, control]
Blast Radius: [lateral movement, escalation paths]

-- Remediation --
Fix: [specific code change, not generic advice]
```
