Precogs AI Insight
"Open Automation Software (OAS) Platform contains an improper authentication vulnerability in the REST API. Attackers bypass security checks to read or write industrial control system (ICS) tags, manipulating physical processes. Precogs API Security Engine maps all endpoints against strict authentication requirements."
What is this vulnerability?
CVE-2022-26833 is categorized as a critical Missing Authentication for Critical Function flaw with a CVSS base score of 9.4. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.
An improper authentication vulnerability exists in the REST API functionality of Open Automation Software OAS Platform V16.00.0121. A specially-crafted series of HTTP requests can lead to unauthenticated use of the REST API. An attacker can send a series of HTTP requests to trigger this vulnerability.
This architectural defect enables adversaries to bypass intended security controls, directly manipulating the application's execution state or data layer. Immediate strategic intervention is required.

Vulnerability Code Signature
Attack Data Flow
| Stage | Detail |
|---|---|
| Source | API Endpoint (REST/GraphQL) |
| Vector | Missing or flawed authorization checks on the requested resource |
| Sink | Direct interaction with database or internal microservice |
| Impact | Unauthorized data access, BOLA/IDOR, Account Takeover |
Vulnerable Code Pattern
// ❌ VULNERABLE: Missing Authorization (BOLA)
app.get('/api/users/:id/data', async (req, res) => {
const userId = req.params.id;
// Taint sink: fetches data for requested ID without verifying ownership
const data = await db.getUserData(userId);
res.json(data);
});
Secure Code Pattern
// ✅ SECURE: Strict Resource Authorization
app.get('/api/users/:id/data', requireAuth, async (req, res) => {
const requestedId = req.params.id;
const authenticatedId = req.user.id;
// Sanitized validation: check ownership
if (requestedId !== authenticatedId && !req.user.isAdmin) {
return res.status(403).json({ error: "Unauthorized access" });
}
const data = await db.getUserData(requestedId);
res.json(data);
});
