Summary

The setContest() lacks proper input validation for it parameters, potentially exposing the contract to vulnerabilities.

Vulnerability Details

1 Invalid Address: without a proper validation, the setContest() could accept invalid address for the organizer and inplementation parameters. This might allow attackers to create contest with unauthorized or non-existent organizers or use malicious implementations.

2 ConstestID Manipulation: The absence of check on the contestId parameter could allow attackers to set contest IDs in unexpected formats, potentially causing conflicts or misrepresentation of contests.

Impact

Invalid contest IDs could result in data corruption or misinterpretation, leading to incorrect contest outcomes and rewards.
Attackers could exploit the lack of address validation to create contests with unauthorized participants or malicious implementations, compromising the integrity of the contests.

Tools Used

Recommendations

Implement robust input validation checks for the setContest function to prevent potential exploits. By adding proper validation, the contract can be safeguarded against potential misuse and vulnerabilities.
