[L-3] Reentrancy Vulnerability in Dussehra::withdraw May Lead to Fund Theft

Description:
The withdraw function in the Dussehra contract sends rewards to the winner (Ram) using a low-level call function. However, the state variable totalAmountGivenToRam is modified after the transfer is initiated, creating a reentrancy risk. An attacker could potentially exploit this vulnerability to drain funds from the contract.

Impact:
While the typical flow of the protocol might not immediately expose this vulnerability, especially since the organizer's fee is transferred upon invoking the killRavana function, it's crucial to address this issue to safeguard against potential exploits. Ensuring the integrity of fund transfers is paramount, particularly in scenarios where unexpected funds accumulate in the contract at the time of withdrawal.

Tools Used:
Manual Review
Recommended Mitigation:
To eliminate the reentrancy risk, it is advised to adjust the order of operations within the withdraw function to follow CEI (Checks, Effects, Interactions). Specifically, the state variable totalAmountGivenToRam should be reset before initiating the fund transfer. This change prevents potential reentrant calls from interfering with the contract's state during the withdrawal process.
