False Positives

• Metasploit’s not perfect, and there might be flaws in it. If Metasploit detects a vulnerability that does not exist in the target system, it will result in false positives.
• If this occurs, it would lead to unnecessary cleanup attempts or a waste of time.

Antivirus and Firewall Detection:

• Security software such as antivirus and firewall may detect and block the exploits of Metasploit.
• It can reduce the efficacy of Metasploit, making it harder for an attack to succeed.

Limited Shell Access:

• You can gain limited shell access to the target system, which is not sufficient for some penetration testing situations.
• For example, you may have to use other tools than Metasploit in order to undertake a large number of remedial actions following exploitation.

No Obfuscation:

• The exploits are not disguised, security software and the administrator of the target system can find them quickly.
• The effectiveness of Metasploit can therefore be reduced and it becomes more difficult to attack successfully.

Limited Reporting Capabilities:

• The reporting capabilities of Metasploit are restricted and may not give the degree of information required for some businesses’ compliance needs.

Dependence on Public Exploits:

• Metasploit relies on publicly available exploits, and there is no guarantee that they will always function. As a result, Metasploit may not discover all vulnerabilities in the target system.

To summarise, while Metasploit is a strong penetration testing tool, it has limits that must be addressed while planning and carrying out penetration testing operations.
