A new security vulnerability, CVE-2022-29303, has been discovered in SolarView Compact ver.6.00. Attackers can leverage this command injection vulnerability to execute arbitrary commands on the target system. This long read post will walk you through the details of this vulnerability, including its source, the risks it poses, and how to protect yourself. We'll also provide code snippets and links to the original references, ensuring that you stay informed and up-to-date.

Command Injection Vulnerability (CVE-2022-29303)

The vulnerability exists in the conf_mail.php file, which does not properly sanitize user inputs before executing commands. An attacker could exploit this by sending a specially crafted string through the $_POST['test_email'] parameter in a malicious web request aimed at the target system. This would enable the attacker to execute arbitrary commands with the privileges of the web server user.

Here is a sample PHP code snippet showcasing the vulnerability in the conf_mail.php file

if (isset($_POST['test_email'])) {
    $email = $_POST['test_email'];
    exec("echo 'This is a test email' | mail -s 'SolarView Test Email' $email");

As you can see, the value of $_POST['test_email'] is not properly sanitized before being passed to the exec() function, which allows an attacker to inject arbitrary commands.

Exploit Details

To launch a successful attack exploiting CVE-2022-29303, an attacker could craft malicious HTTP POST request like this:

POST /conf_mail.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
Content-Length: 73
Connection: close


In this example, the attacker sends an email and injects the "whoami" command to be executed on the target system. The result of the "whoami" command is then stored in a file named "whoami.txt," which the attacker can later access to examine the output.
