First Flight #1: PasswordStore

Summary

The primary objective of this contract is to restrict access to the setPassword function to only the admin. However, there is currently no mechanism in place to identify the caller of this function.

Vulnerability Details

The contract lacks any access control mechanism, allowing anyone to access and set the password. There is no check or require statement to verify the caller's identity when calling the setPassword function.

Impact

The absence of access control measures in the contract results in a critical vulnerability. Any user, not just the admin, can set the password, which undermines the intended security of the contract.

Tools Used

The identified vulnerability was detected through manual inspection.

Recommendations

To address this vulnerability, it is essential to implement access control mechanisms. One common approach is to utilize a require statement for the setPassword function to verify the caller's identity. Access should be restricted to the admin or authorized parties only, ensuring the contract functions as intended.
