Executive Summary
Nodcms contains a cross-site request forgery vulnerability that allows attackers to perform unauthorized administrative actions by crafting malicious forms. Attackers can trick authenticated administrators into submitting requests to admin/user_manipulate and admin/settings/generall endpoints to create users or modify application settings without explicit consent.
Quantitative Risk Analysis
Attack Vector Profile
The payload vectors broken down by magnitude impact and ease-of-deployment factor mapping.
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:NWhat This Means For Your System
Each point below is derived directly from this CVE's CVSS v3.1 vector — not editorial opinion.
Exploitable remotely over the internet — no physical or local access needed.
No special preconditions — the attack is reliably repeatable.
A basic authenticated account is sufficient to trigger this.
No user interaction required — the attacker acts autonomously.
Successful exploitation causes: limited data modification.
OsVault Risk Score Methodology
The OsVault composite score is a 5-layer non-linear engine — not a simple weighted average. Each input signal is transformed through mathematically appropriate curves before blending, ensuring that exploitability context overrides raw severity when warranted.
Layer 1 (Technical): CVSS is mapped through a piecewise exponential curve with 4 bands (LOW 0–20, MEDIUM 20–55, HIGH 55–85, CRITICAL 85–100), then multiplied by full CVSS vector decomposition factors for Attack Vector, Complexity, Privileges, and User Interaction.
Layer 2 (Threat): Raw EPSS is passed through a logistic sigmoid (k=40, midpoint=0.05) to maximize discrimination in the decision-relevant range. The result is added to an exploit maturity tier base score (Weaponized: 85, Functional: 55, PoC: 40, Unproven: 18).
Layer 3 (KEV Floor):Any CVE in CISA's catalog receives a hard minimum of 93.0 (Functional) or 97.0 (Weaponized). This ensures confirmed exploitation is never buried by low CVSS scores.
Scores ≥70: patch immediately. 40–69: schedule within current sprint. Below 40: standard maintenance cycle.
