Web Application Potentially Sensitive CGI Parameter Detection

Purushotham — Fri, 12 Jan 2024 08:44:46 GMT

Need to check any advisory released by Palo Alto on the above mentioned Vulnerability and make sure that it does not leak any confidential information, or sensitive data will not be disclosed.

Description:

According to their names, some CGI parameters may control sensitive data (e.g., ID, privileges, commands, prices, credit card data, etc.). In the course of using an application, these variables may disclose sensitive data or be prone to tampering that could result in privilege escalation. These parameters should be examined to determine what type of data is controlled and if it poses a security risk.

VA Scan Output:

Name:Web Application Potentially Sensitive CGI Parameter Detection

Port:443

Sypnosis:

An application was found that may use CGI parameters to control sensitive information.

Description:

"According to their names, some CGI parameters may control sensitive

data (e.g., ID, privileges, commands, prices, credit card data, etc.).

In the course of using an application, these variables may disclose

sensitive data or be prone to tampering that could result in privilege

escalation. These parameters should be examined to determine what

type of data is controlled and if it poses a security risk.

** This plugin only reports information that may be useful for auditors

** or pen-testers, not a real flaw."

Solution:

Ensure sensitive data is not disclosed by CGI parameters. In

addition, do not use CGI parameters to control access to resources or

privileges.

Plugin Output:

Potentially sensitive parameters for CGI /php/login.php :

user : Potential horizontal privilege escalation - try another user ID

passwd : Possibly a clear or hashed password, vulnerable to dictionary attack
