CVE-2026-40818
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn unauthenticated remote attacker can exploit an unauthenticated SQL Injection vulnerability in the _mb24confi_getDevice function due to improper neutralization of special elements in a SQL SELECT command. This can result in a total loss of confidentiality.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn unauthenticated remote SQL injection vulnerability exists in the _mb24confi_getDevice function due to improper neutralization of special elements in SQL SELECT commands. Attackers can exploit this to execute arbitrary SQL queries, resulting in total loss of confidentiality.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the vulnerable _mb24confi_getDevice function in your codebaseSearch your application source code for the string '_mb24confi_getDevice' using grep or a similar file search tool. Identify the file(s) containing this function.Affected if The function exists in your deployed application code.
-
Determine if the function is exposed without authenticationReview the code that calls _mb24confi_getDevice. Check the access control settings (authentication/authorization decorators or middleware) on the endpoint or API route that invokes this function.Affected if The function can be reached without any authentication or authorization checks.
-
Inspect how user input is handled in the functionExamine the _mb24confi_getDevice function body. Trace all parameters received and determine how they are incorporated into SQL queries. Look for direct string concatenation, string interpolation, or unsanitized input placement into SQL statements.Affected if User-controllable input is directly embedded into SQL queries without using parameterized queries or prepared statements.
-
Check for SQL query construction patternsWithin the _mb24confi_getDevice function, locate all SQL SELECT statements. Verify whether they use placeholders (?, :param, etc.) with bound parameters or if they build queries by concatenating strings that include user input.Affected if SQL queries are constructed by concatenating user input or request parameters directly into the query string.
-
Verify network exposure of the vulnerable endpointIdentify the web endpoint or API route that triggers _mb24confi_getDevice. Confirm whether it is accessible from the network and accepts remote requests without authentication.Affected if The vulnerable function is accessible via an unauthenticated network request.
Your environment is affected if the _mb24confi_getDevice function exists in your deployment, is network-accessible without authentication, and processes user input directly into SQL queries without parameterized query protection.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace dynamic SQL queries with parameterized queries or prepared statements in the _mb24confi_getDevice function and implement proper input validation to neutralize SQL injection vectors.
