Metascan is a powerful and flexible solution for detecting and preventing known and unknown threats. You can submit up to 5 files at the same time. There is a 50MB limit per file.

If you discover a suspicious file on your machine, or suspect that a program you downloaded from the internet might be malicious you can scan it here.
Enter the file name to be checked in the box to the right and it will automatically be uploaded from your computer to a dedicated server where it will be scanned using FortiClient Antivirus. Triggering this vulnerability could result in memory corruption on the server, potentially crashing certain programs or the server itself.
Hackers could also use this file upload exploit to crash the real-time security monitoring, then perform another kind of attack. Uploading certain types of malicious files can make a WordPress website vulnerable to client-side attacks like cross-site content hijacking and XSS attacks. Hackers might also be interested in uploading files that trigger vulnerabilities in the libraries or applications used by end-user devices.
Malicious files including Windows viruses, Unix shell scripts and Excel files may be uploaded if there are unrestricted file uploads. A server administrator or webmaster might discover these files, then open them to determine what they are — executing the code and allowing malware onto your server. If your website publishes user-uploaded content, allowing unrestricted file uploads may result in your website being defaced or used for a phishing attack. Hackers often target unsecured file upload systems to store troublesome files.
These files might include illegal software downloads, pornographic material, stolen intellectual property, malware, or data used by criminal organizations. This information might include file paths or folder permissions. Unsecured file upload forms may allow hackers to upload extremely large files or hundreds of files at once — performing a denial of service attack.
This vulnerability occurs in systems where any type of file can be uploaded to the server. It also occurs when the file type is not adequately verified by the server. This vulnerability could allow cybercriminals to upload any kind of executable file to the server. In some cases, website owners might check the file extension of an uploaded file, but fail to verify that it matches the contents of the file which has been uploaded.
To avoid this vulnerability, the application must thoroughly check the files that are being uploaded and remove file types that can cause damage to the server. The application should not rely solely on Content-Type HTTP header information when checking file types, but instead, use more detailed file checking processes. This vulnerability is created when a user is allowed to upload a file without being authenticated by the application.
The ability to upload should be restricted to authenticated users to prevent malicious individuals from uploading random files to your server. Allowing arbitrary file uploads also puts your site at greater risk of a denial of service attack. Applications should place restrictions on the size of files that can be uploaded and the number of files that can be uploaded.
Generic; using System. IO; using System. Linq; using System. Net; using System. ToInt32 this. This is a sample file used to test the response of anti-virus software. You can download a sample file from this Site. You may need to pause your antivirus protection on your device to perform this activity. Using their own Clam Av Ip address to scan our files To scan the documents without docker image and if the clam av server is already installed in our machine we need to change a bit of code in the API level instead of going with docker port.
Here is the following code, FileController. Parse " First, you have to check what kind of API does your installed antivirus software provides. Dushyant Singh Dushyant Singh 41 4 4 bronze badges.
