CASE STUDY: ROLE MISCONFIGURATION IN A YIELD AGGREGATOR

Bug Class: Access Control | Severity: Critical/Medium | Payout Range: $10K–$50K This file shows how to apply the full 10-class methodology to a real yield aggregator target.

TARGET PROFILE (Anonymized)

Field	Value
Protocol Type	Yield aggregator — stablecoin → lending protocol → harvest → DEX → reward token
Max Bounty	$50K (Critical)
TVL	Low (fresh program, under $100K)
Core Contracts	Vault.sol, RewardsDistributor.sol
Program Age	~5 days when hunted (fresh = low competition)
Prior Audits	Firm A (16 findings, all Risk Accepted) + Firm B (18 findings, all Risk Accepted)

Scorecard: Max bounty (+2) + custom math (+1) + recent code (+1) + known prior audits (+1) + public source (+1) + program new (+2) = 8/10 → HUNT

Why this scores high: Fresh program on a live bounty platform + prior audits that accepted all risk = team is aware of issues but hasn't patched them. Hunt for what auditors missed or flagged but accepted.

ARCHITECTURE + FUND FLOW

User deposits Stablecoin
    ↓ deposit(uint256 amount)
Vault.sol stores:
  - deposits[user] += amount
  - totalDeposited += amount
  - depositTimestamp[user] = block.timestamp
    ↓ safeTransferFrom(user, address(this), amount)
    ↓ lendingProtocol.supply(stablecoin, amount, address(this), 0)
  Interest-bearing token accrues in Vault.sol balance
    ↓ (periodic) _performHarvest()
  aToken balance > totalDeposited + DUST_THRESHOLD
    ↓ lendingProtocol.withdraw(stablecoin, harvestAmount - 1, address(this))
    ↓ dex.exactInputSingle(stablecoin → rewardToken)
    ↓ RewardsDistributor.distribute(rewardToken, amount)
  RewardsDistributor tracks:
  - cumulativeRewardPerShare updates
  - users can call claimFor(user) to collect rewardToken

User withdraws:
    ↓ withdraw(uint256 amount)
  if block.timestamp < depositTimestamp[user] + LOCK_PERIOD:
    withdrawFee applies (e.g. 0.5%)
  lendingProtocol.withdraw(stablecoin, amount, user)

Key state variables:

deposits[user] — user principal (stablecoin)
totalDeposited — sum of all principals
depositTimestamp[user] — last deposit time (affects withdrawal fee)
cumulativeRewardPerShare — reward index in RewardsDistributor
lastClaimedReward[user] — user's last reward index

KNOWN ISSUES (Risk Accepted by Team — Do NOT Submit)

Firm A Findings (16 total, all Risk Accepted)

All standard: missing events, gas optimizations, reentrancy guards present (CEI followed), centralization risks (owner can pause), single oracle (DEX swap is operational, not security-critical).

Firm B Findings (18 total, all Risk Accepted)

Including:

HAL-01: withdrawFee can be changed by owner (centralization)
HAL-05: deposit() resets depositTimestamp even on partial top-ups → extends lock period for existing deposits
HAL-08: Missing check for DISTRIBUTOR_ROLE being set (flagged but did NOT verify it was never granted)
Various gas and event issues

Pattern: Firm B flagged "missing check" but didn't verify the role was actually ungranted. This is the gap to exploit.

BUG CLASS VERDICTS

1. Accounting Desync — 2 FINDINGS

Finding 1: The -1 Stranding Pattern

// In _performHarvest():
harvestAmount = aToken.balanceOf(address(this)) - totalDeposited - 1; // strands 1 wei

The hardcoded -1 strands 1 wei of stablecoin per harvest permanently. Over thousands of harvests, this accumulates. Severity: LOW/INFORMATIONAL (no user loss, just protocol dust accumulation).

Finding 2: Dust Harvest DoS ← VALID MEDIUM

Scenario: Accumulated harvest amount is very tiny (< DEX minimum swap)
1. harvest() calls dex.exactInputSingle(stablecoin → rewardToken)
2. DEX returns 0 (amount too small to produce any output)
3. RewardsDistributor.distribute(0) is called
4. If distribute() reverts on 0 amount → harvest is permanently frozen
5. Users can still withdraw principal but all future yield is lost

Verification: Check if distribute(0) reverts. Check DEX minimum swap threshold.

2. Access Control — 1 FINDING (CRITICAL/HIGH)

Finding: DISTRIBUTOR_ROLE Never Granted ← MAIN FINDING

// RewardsDistributor.sol
bytes32 public constant DISTRIBUTOR_ROLE = keccak256("DISTRIBUTOR_ROLE");

function claimFor(address user) external {
    require(hasRole(DISTRIBUTOR_ROLE, msg.sender), "Not distributor");
    // ... distribute rewardToken to user
}

Problem: DISTRIBUTOR_ROLE is defined but NEVER granted in the constructor or any initialization function. No address holds this role. claimFor() can never succeed — all reward tokens are permanently locked.

How Firm B missed it: They flagged "missing check for whether role is set" — but their fix recommendation was "add a require that checks the role exists." They didn't verify that getRoleMemberCount(DISTRIBUTOR_ROLE) == 0 on the live deployment.

Severity Assessment:

If harvest HAS already happened: CRITICAL (funds locked forever)
If harvest never happened yet: HIGH (permanent lock when it does happen)
Impact × Likelihood × Exploitability: 3 × 3 × 3 = 27 → CRITICAL

Verification commands:

# Check if any address has DISTRIBUTOR_ROLE (replace with actual address)
cast call <REWARDS_DISTRIBUTOR_ADDR> \
  "getRoleMemberCount(bytes32)(uint256)" \
  "$(cast keccak 'DISTRIBUTOR_ROLE')"
# Expected: 0 = confirmed bug

# Alternative: Etherscan → Events → filter "RoleGranted"
# If no RoleGranted events with DISTRIBUTOR_ROLE hash = confirmed

3. Incomplete Path — Known (Risk Accepted)

Firm B HAL-05: deposit() resets depositTimestamp[user] even on partial top-ups, extending the lock period for all existing deposits. Risk Accepted by team.

4. Off-by-One — CLEAN

All boundary operators (>=, <) in Vault.sol and RewardsDistributor.sol are correct.

5. Oracle Price — CLEAN

Protocol does NOT use price oracles for security decisions (no lending, no liquidation, no collateral). The DEX swap is operational (converting yield), not security-critical. MEV/sandwich risk exists but is a griefing/efficiency issue, not a theft vulnerability.

6. ERC4626 Vaults — NOT APPLICABLE

Uses a custom 1:1 share model, NOT ERC4626:

deposits[user] tracks exact principal
No share price, no share-based rounding
Transfers between users are blocked
First depositor inflation attack does NOT apply

7. Reentrancy — CLEAN

Follows CEI (Checks-Effects-Interactions) correctly:

deposits[user] += amount BEFORE lendingProtocol.supply()
deposits[user] -= amount BEFORE lendingProtocol.withdraw()
Missing nonReentrant guard, but CEI makes it safe. Not submittable without PoC.

8. Flash Loan — CLEAN (Economically)

Flash loan attack would attempt: deposit → dilute harvest → withdraw to steal yield. The withdrawFee makes this unprofitable:

Attacker deposits $1M → harvest dilutes → attacker gains $0 extra yield
But: attacker pays withdrawal fee to exit
Net: negative expected value → NOT PROFITABLE

9. Signature Replay — NOT APPLICABLE

No signature-based functions, no EIP-2612 permit, no meta-transactions.

10. Proxy/Upgrade — NOT APPLICABLE

Not upgradeable proxies. No proxy pattern.

WHAT TO SUBMIT

SUBMIT (2 findings):

Finding 1 — CRITICAL/HIGH:

Title: DISTRIBUTOR_ROLE never granted in RewardsDistributor.sol,
       permanently locking all reward tokens

Root Cause: DISTRIBUTOR_ROLE is defined but grantRole() is never called
            in constructor or initialization. No address holds this role.

Impact: All rewards distributed by harvest() are permanently locked —
        claimFor() always reverts.
        Users receive zero yield despite depositing and paying withdrawFee.

Attack Path: Not an attack — passive failure. Any harvest → rewards locked forever.

Severity: Critical (if harvest has occurred) / High (if not yet)

Finding 2 — MEDIUM:

Title: _performHarvest() dust harvest causes permanent DoS on yield distribution

Root Cause: When accumulated yield rounds to < DEX minimum swap amount,
            exactInputSingle() returns 0 output. distribute(0) may revert or
            permanently advance the reward index with no rewards.

Impact: After a dust harvest, all subsequent harvests may fail permanently.

Severity: Medium (requires specific conditions but permanently impacts yield)

DO NOT SUBMIT:

The -1 stranding (informational, design choice)
depositTimestamp reset (Risk Accepted by team)
Missing nonReentrant (CEI is followed; no PoC = no submission)
Owner centralization (excluded by design in Immunefi SC programs)
Any of the already-acknowledged findings from prior audits

REPORT TEMPLATE

Title: Missing DISTRIBUTOR_ROLE grant permanently locks all rewards for all users

Bug Description: RewardsDistributor.sol defines DISTRIBUTOR_ROLE and requires it to call claimFor(). However, grantRole(DISTRIBUTOR_ROLE, ...) is never called in the constructor, any initialization function, or any privileged setter. No address holds this role. claimFor() always reverts.

The Vault contract calls RewardsDistributor.distribute() after each harvest, successfully depositing reward tokens into the distributor. However, these tokens can never be claimed — permanently locked.

Root Cause: Constructor is missing grantRole(DISTRIBUTOR_ROLE, vaultContract).

Impact: All yield earned by all depositors is permanently locked in RewardsDistributor.sol. Users cannot receive any return from their deposits.

## REPORT TEMPLATE

**Title:** Missing DISTRIBUTOR_ROLE grant permanently locks all rewards for all users

**Bug Description:**
`RewardsDistributor.sol` defines `DISTRIBUTOR_ROLE` and requires it to call `claimFor()`. However, `grantRole(DISTRIBUTOR_ROLE, ...)` is never called in the constructor, any initialization function, or any privileged setter. No address holds this role. `claimFor()` always reverts.

The Vault contract calls `RewardsDistributor.distribute()` after each harvest, successfully depositing reward tokens into the distributor. However, these tokens can never be claimed — permanently locked.

**Root Cause:** Constructor is missing `grantRole(DISTRIBUTOR_ROLE, vaultContract)`.

**Impact:** All yield earned by all depositors is permanently locked in RewardsDistributor.sol. Users cannot receive any return from their deposits.
