A critical vulnerability, CVE-2022-4232, has been identified in SourceCodester Event Registration System 1.. This vulnerability allows an attacker to upload and execute malicious files, providing the attacker with the capability to execute remote code on the target system. The vulnerability exists in an unknown function of the Event Registration System and has been assigned the identifier VDB-214590.

In this post, we will delve deeper into the exploit details, including a snippet of the malicious code used in the attack and provide links to original references for further information.

Exploit Details

The vulnerability arises from the manipulation of the "cmd" argument within the SourceCodester Event Registration System. An attacker can exploit this by remotely uploading a malicious file, which can then be executed on the target system.

The following snippet illustrates a sample of the malicious code used in the attack

POST /event_regis_system/ HTTP/1.1
...
Content-Disposition: form-data; name="cmd"; filename="malicious.php"
Content-Type: application/x-php

<?php
  echo "This is a malicious PHP script";
  // Insert malicious PHP code here
?>

In this sample code, the attacker uploads a PHP file containing malicious code. Once the file is uploaded to the server, the attacker can then execute the code remotely, potentially causing significant damage to the target system.

Attack Vector: Remote

The vulnerability can be exploited remotely, meaning that an attacker does not need physical access to the target system. Hence, the risk associated with this vulnerability is much higher, as any attacker with knowledge of this exploit can potentially compromise the system from anywhere in the world.
