To fix the issue, we will add the readonly modifier to the adminUserName field. This ensures that the field cannot be reassigned after its initial value is set during declaration. The change will be made directly in the declaration of the field on line 9.

To fix the issue, replace the Request.Query.ContainsKey("drive") check and subsequent access to Request.Query["drive"] with a single call to Request.Query.TryGetValue. This approach combines the key existence check and value retrieval into one operation, improving efficiency and readability.
Specifically:
- Replace the conditional expression on line 25 with a call to
Request.Query.TryGetValue. - Use the
outparameter ofTryGetValueto retrieve the value of the "drive" key if it exists, or assign the default value"C"if it does not.

Log entries created from user input High

To fix the issue, the user-provided input (drive) should be sanitized before being included in the log entry. Since the log entry is plain text, we can remove newline characters and other potentially problematic characters from the drive parameter. This can be achieved using String.Replace or a similar method to ensure that the log entry cannot be manipulated by malicious input.
Specifically:
- Sanitize the
drivevariable by removing newline characters (\n,\r) and any other characters that could interfere with log formatting. - Use the sanitized
drivevariable when constructing thestrvariable and logging the message.

To fix the issue, we should handle the exception properly. This can involve logging the error, providing a meaningful message, or taking corrective action. In this case, since the code is attempting to access elements of a list, an IndexError is the likely exception. We can log the error or print a message indicating the issue. Additionally, we should avoid using a bare except: clause and instead catch specific exceptions.

To fix the issue, we will replace the bare except: block with an except Exception: block. This ensures that only exceptions derived from Exception are caught, leaving KeyboardInterrupt and SystemExit to propagate as they should. Additionally, we will add a comment to clarify the intent of the exception handling.
For the second occurrence on line 16, where another bare except: block is used, we will similarly replace it with except Exception: to handle only expected exceptions.

To fix the issue, the except: block on line 16 should be replaced with an except Exception: block. This ensures that only exceptions derived from Exception are caught, leaving KeyboardInterrupt and SystemExit to propagate as intended. This change aligns with Python's best practices for exception handling and avoids the risks associated with catching BaseException.
