CVE-2023-4015

A use-after-free flaw was found in the Linux kernel's netfilter: nftables component, which can be exploited to achieve local privilege escalation. On an error when building a nftables rule, deactivating immediate expressions in nftimmediatedeactivate can unbind the chain and objects can be...

CVE-2023-3777

A use-after-free flaw was found in the Linux kernel's netfilter: nftables component, which can be exploited to achieve local privilege escalation. When nftablesdelrule is flushing table rules, it is not checked whether the chain is bound, and the chain's owner rule can release the objects in...

A vulnerability was found in the BusyBox package. This issue occurs via a stack overflow vulnerability in ash.c in BusyBox, which may allow arbitrary code execution. Mitigation Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product...

Calculating slippage from price oracle is not accurate

Lines of code Vulnerability details Impact calculating slippage using oracle prices will lead to inaccurate slippage values , due to this swaps will fail or execute with higher slippage. Proof of Concept In curveSwap function of RdpxV2Core contract slippage is being calculated using oracles price...

Flashloan/Sandwich Attacks on UpdateFunding()

Lines of code Vulnerability details Impact The attacker can launch a sandwich/flashloan attack on the updateFunding function to gain most of the reward. Proof of Concept 1. The attacker observed that some reward is going to be distributed via updateFunding function. 2. The attacker borrowed...

Users can withdraw token multiple times by calling `withdrawStake' thereby depleting the treasury

Lines of code Vulnerability details The withdrawStake function is used to withdraw tokens for an unbounding lock that has existed through an unbounding period. All it needs is the unbondingLockId to carry out the operation. The associated ID gets deleted & the amount that has been bounded is...

A difference in the rDPX price between the oracle and DEXs used for trading can cause more slippage than expected

Lines of code Vulnerability details Impact The protocol will experience much higher slippage than supposed to due to using the wrong price in calculating the amount after slippage. Proof of Concept The protocol executes swaps on Uniswap and Curve. The issue arises due to the protocol using its ow...

PT-2023-6899

Name of the Vulnerable Software and Affected Versions Apache Superset versions up to and including 2.1.0 Description The issue is related to an improper default REST API permission for Gamma users in Apache Superset, which is connected to shortcomings in the authorization mechanism. This allows a...

Incorrect usage of an uninitialized earnings pool if lastRewardRound >= currentRound.

Lines of code Vulnerability details Impact If lastRewardRound = currentRound, the earningsPool for currentRound may not be initialized if reward has not yet been called for currentRound. So using it to update cumulative rewards or fees could be incorrect. This can lead to incorrect reward...

Initialization Issue in EarningsPoolL

Lines of code Vulnerability details Impact the vulnerable part in code : uint256 prevCumulativeRewardFactor = prevEarningsPool.cumulativeRewardFactor != 0 ? prevEarningsPool.cumulativeRewardFactor : PreciseMathUtils.percPoints1, 1; earningsPool.cumulativeRewardFactor =...

Incorrect slippage calculation in _curveswap function

Lines of code Vulnerability details Impact swaps will fail or execute with higher slippage than intended. Proof of Concept In curveSwap function of RdpxV2Core contract , getEthPrice should be used in place of getDpxEthPrice, and getDpxEthPrice should be used in place of getEthPrice. / @notice...

.The _newPosPrev/_newPosNext hints do not fully prevent invalid ordering when decreasing a delegate's stake.

Lines of code Vulnerability details Impact The contract could incorrectly deactivate or reward transcoders based on the invalid pool order. Proof of Concept When decreasing a delegate's stake with decreaseTotalStake, the contract calls transcoderPool.updateKey to update the delegate's position in...

A malicious delegator could artificially inflate the deductions for a transcoder, potentially leading to incorrect vote counting.

Lines of code Vulnerability details Impact Detailed description of the impact of this finding. Proof of Concept In the handleVoteOverrides function, the deductions are added to the transcoder's voter state without any validation: A malicious delegator could call countVote multiple times, each tim...

Front-running attack can occur between when the unbonding lock is created and when the delegator's bonded amount is decreased.

Lines of code Vulnerability details Impact This would allow the delegator to temporarily have more bonded tokens than they should. They could take advantage of this by voting in governance with the increased voting power or withdrawing increased fees Proof of Concept 1. When unbond is called, an...

Malicious users can manipulate the withdrawRound to withdraw their stake before the unbonding period is over.

Lines of code Vulnerability details Impact Disruption the normal bonding incentives and mechanisms in the protocol. Validators or transcoders could withdrew unexpectedly, preventing governance responses to bonded token changes. Proof of Concept The withdrawStake function first checks if the...

The quorum calculation in the _quorumReached() function is inconsistent and could allow abstain votes to prevent a proposal from reaching quorum even if most participating voters are in favor

Lines of code Vulnerability details Impact This allows abstain voters to effectively veto a proposal, even if most participating voters approve it. Proof of Concept The quorum numerator and denominator are inconsistent. The quorum uses totalVotes for the denominator which includes abstains. But t...

Zero Redemption Amount in RdpxDecayingBonds Contract

Lines of code Vulnerability details Impact The redeem function, as described, checks whether the assets to be redeemed assets are not zero. This check is in place to ensure that a user isn't redeeming a non-zero amount of rdpxAmount tokens in exchange for zero assets. Such a check is essential to...

Calling withdraw on a delegated amount of WETH doesn't subtract from totalWethDelegated

Lines of code Vulnerability details Impact The contract's WETH amount gets permanently bricked. Proof of Concept A user can call addToDelegate and give WETH, that other people can use for bonding with their rDPX in exchange for a certain percentage appointed by the delegatee. Delegate memory...
