TempleGold

Summary

Unauthorized access to critical functions in smart contracts can lead to serious vulnerabilities. These functions can be exploited by malicious actors to alter the contract state, perform unauthorized transactions, or cause unintended side effects. In the DaiGoldAuction contract, certain functions such as distributeGold, which calls _distributeGold(), lack proper access controls, potentially allowing any user to call these functions.

Vulnerability Details

The distributeGold function, which calls _distributeGold(), can be called by anyone.

Impact

• If unauthorized users can call distributeGold, they might trigger unintended token distributions, potentially draining the contract of its tokens.

• Unauthorized access could lead to the improper allocation or loss of funds, affecting the integrity and financial stability of the auction system.

• Unauthorized access could disrupt the auction process, leading to incorrect auction outcomes and unfair distribution of assets.

Recommendations

Restrict access using a modifier like onlyElevatedAccess. The onlyElevatedAccess modifier restricts the execution of certain functions to only those addresses that have elevated or administrative privileges. This ensures that only authorized entities can invoke critical operations, enhancing the security and integrity of the contract. It restricts critical operations to trusted entities, reducing the risk of unauthorized actions. It allows only specific addresses to perform sensitive actions, ensuring proper governance and control.
