RIPR [RISE2PROTOCOL] Token

RISE2PROTOCOL.swapBack() (#648-695) sends eth to arbitrary user
Dangerous calls:
- (tmpSuccess) = address(marketingWallet).call{gas: 30000,value: marketingShare}() (#678)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

DividendDistributor.distributeDividend(address) (#278-289) ignores return value by RewardToken.transfer(shareholder,amount) (#284)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Additional information: link

Too many vulnerabilities (Unchecked transfer, Reentrancy vulnerability, etc.). High risk of a scam. DYOR & manual audit are advised.

RISE2PROTOCOL.swapBack().tmpSuccess (#678) is written in both
(tmpSuccess) = address(marketingWallet).call{gas: 30000,value: marketingShare}() (#678)
tmpSuccess = false (#681)
Fix or remove the writes.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
