This manipulation of the argument img causes unrestricted upload. It is possible to initiate the attack remotely. The exploit has been published and may be used.
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 confidenceSourceCodester Online Exam Form Submission 1.0 contains an unrestricted file upload vulnerability in /register.php. The 'img' parameter accepts arbitrary file types without proper validation, allowing remote attackers to upload malicious files (e.g., PHP shells) and potentially achieve remote code execution on the server.

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.
-
Confirm the application is installedSearch for files matching 'online exam', 'janobe', or 'SourceCodester' in your web root directory. Look for directory names containing 'online_exam' or similar naming patterns.Affected if The application directory is found on the server
-
Verify the application versionCheck the source code for a version identifier. Look in README files, config files, or the main PHP files for a version number such as '1.0'. Compare against the affected version range.Affected if The installed version is 1.0
-
Locate the vulnerable upload scriptCheck if /register.php exists in the web root. This file is typically in the main application directory accessible via the web server.Affected if The file /register.php is present and accessible via HTTP/HTTPS
-
Inspect the upload form configurationExamine the /register.php source code around the 'img' parameter. Look for file type validation logic (checking file extensions, MIME types, or magic bytes). Check if any whitelist or blacklist validation is implemented.Affected if No file extension, MIME type, or content validation is present for the 'img' upload field
-
Check the uploads directory placementLocate where uploaded files are stored. Examine the upload handling code to find the destination folder. Determine if this folder is inside or outside the webroot.Affected if Uploaded files are stored within the web-accessible directory and script execution is not disabled in that folder
The environment is affected if the Online Exam Form Submission version 1.0 is installed, the /register.php file exists, and uploaded files are stored in a web-accessible location without proper file type validation.
Generated from the published advisory. Verify against your own configuration.
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 strict file upload validation: validate file extension, MIME type, and file content (magic bytes); store uploads outside the webroot or disable script execution in the upload directory; rename uploaded files and enforce size limits.
