CVE-2023-45117
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 · uneditedOnline Examination System v1.0 is vulnerable to multiple Authenticated SQL Injection vulnerabilities. The 'eid' parameter of the /update.php?q=rmquiz resource does not validate the characters received and they are sent unfiltered to the database.
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 confidenceOnline Examination System v1.0 contains an authenticated SQL injection vulnerability in the 'eid' parameter of /update.php?q=rmquiz. The application fails to validate or sanitize user input before using it in SQL queries, allowing authenticated attackers to inject malicious SQL commands.

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.
-
Identify the installed version of Online Examination SystemCheck the application documentation, source code headers, or any version file. If deployed, review the deployment artifacts or package management records for version 1.0.Affected if The installed version is Projectworlds Online Examination System version 1.0
-
Locate the update.php fileSearch the web root directory for the presence of update.php. Common paths include /update.php or /admin/update.php depending on deployment structure.Affected if The file update.php exists in the application directory
-
Verify the rmquiz functionality existsInspect update.php for the 'q=rmquiz' parameter handling. Search for code that processes the 'eid' parameter in the context of rmquiz operations.Affected if The update.php file contains logic handling the 'eid' parameter for rmquiz functionality
-
Confirm the application is network-accessibleDetermine if the web application is accessible over HTTP/HTTPS from network locations. Check web server configuration and firewall rules.Affected if The application is exposed on a network and reachable by potential attackers
-
Review authentication controls for the affected endpointCheck whether the update.php?q=rmquiz endpoint requires authentication. Determine if unauthenticated access is possible or if valid credentials are required.Affected if An attacker can obtain valid authentication credentials to access the vulnerable endpoint
The environment is affected if running Online Examination System version 1.0 with the update.php file present and the application is network-accessible to authenticated attackers who can reach the rmquiz functionality via the eid parameter.

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 dataImplement prepared statements/parameterized queries for all database operations, particularly for the 'eid' parameter in update.php. Apply input validation and output encoding as defense-in-depth measures.
