This version is vulnerable to a command injection attack where an attacker can inject malicious commands into the running web server. This may be leveraged for various attacks such as remotely installing malware & setting up a backdoor.
Symptoms of this vulnerability may include:
1) Inability to access the web server via a web browser.
2) Inability to access the web server via SSH.
3) Inability to access the web server via rlogin.
4) Inability to access the web server via telnet.
5) Inability to access the web server via SNMP.
6) Inability to access the web server via Apache error page.
7) Inability to access the web server via SWAT/Boss.
8) Inability to access the web server via cURL.
9) Inability to access the web server via any non-standard protocol.
10) Inability to access the web server via any protocol.
11) Inability to access the web server via any non-standard port.
12) Inability to access the web server via any non-standard host.
13) Inability to access the web server via any non-standard path.
14) Inability to access the web server via any non-standard login.
15) Inability to access the web server via any non-standard password.
16)
Solution
The solution to this vulnerability is to upgrade the web server software.
What is Web Server Command Injection?
Web Server Command Injection, also known as "SQL Injection," is a type of attack where the attacker injects SQL commands into the web server's input. This allows the attacker to perform actions by sending XML requests to the web server, which may be leveraged for various attacks such as remotely installing malware & setting up a backdoor. Web servers are vulnerable to command injection because they rely on user input, which can be delivered in many different forms that can be read and parsed by an attacker who is exploiting this vulnerability.
The following example demonstrates how an attacker would exploit this vulnerability:
