Vulnerabilities

Improper Access Control

Property
Language	solidity
Severity
CWE	CWE-284: Improper Access Control
Confidence Level	Medium
Impact Level	High
Likelihood Level	High

Description

The oracle update function in your smart contract is missing access control, allowing anyone to call it. This means that unauthorized users can update or manipulate oracle data.

Impact

If exploited, an attacker could feed false or manipulated data to your application by updating the oracle, potentially leading to financial loss, incorrect contract behavior, or exploitation of protocol logic. This could compromise user funds and undermine trust in the contract.

Improper Access Control

Property
Language	solidity
Severity
CWE	CWE-284: Improper Access Control
Confidence Level	Low
Impact Level	High
Likelihood Level	High

Description

The contract allows anyone to update oracle price data without any access restrictions. This means that untrusted users can submit arbitrary price information to the system.

Impact

An attacker could manipulate price data, leading to incorrect asset valuations, potential financial loss, and exploitation of trading or lending mechanisms reliant on these prices. This can result in stolen funds, market manipulation, or collapse of trust in the platform.

Improper Access Control

Property
Language	solidity
Severity
CWE	CWE-284: Improper Access Control
Confidence Level	Medium
Impact Level	High
Likelihood Level	High

Description

The custom ERC721 contract’s _transfer() function does not check if the caller is the owner or an approved account before transferring tokens. This lack of access control allows anyone to transfer NFTs without proper authorization.

Impact

Without these checks, attackers could transfer or steal NFTs from any user, leading to unauthorized asset loss, financial damage, and loss of trust in the contract. This vulnerability puts all token holders at risk of having their NFTs taken without consent.

Improper Access Control

Property
Language	solidity
Severity
CWE	CWE-284: Improper Access Control
Confidence Level	Low
Impact Level	High
Likelihood Level	Medium

Description

The Uniswap callback function in your contract is missing proper access control checks to ensure only authorized Uniswap pool contracts can call it. Without these validations, any external entity could trigger the callback and potentially manipulate your contract’s logic.

Impact

If exploited, an attacker could call the callback function directly, bypassing expected Uniswap behavior and potentially draining funds, executing unauthorized transactions, or disrupting contract operations. This could lead to significant financial losses and compromise the integrity of your smart contract.

Improper Access Control

Property
Language	solidity
Severity
CWE	CWE-284: Improper Access Control
Confidence Level	Low
Impact Level	High
Likelihood Level	High

Description

The _transfer() function in your ERC20 contract is set to public or external, allowing anyone to call it directly. This bypasses intended access controls and exposes internal transfer logic to arbitrary external calls.

Impact

Attackers could transfer tokens between accounts without proper authorization, potentially draining user balances or manipulating funds. This can lead to loss of assets, contract compromise, and severe trust issues for the token ecosystem.

Improper Access Control

Property
Language	solidity
Severity
CWE	CWE-284: Improper Access Control
Confidence Level	Low
Impact Level	High
Likelihood Level	High

Description

The transferOwnership function is publicly accessible without proper access control, allowing anyone to change the contract’s owner. This means unauthorized users can take ownership of the contract.

Impact

If exploited, an attacker could seize control of the smart contract, potentially transferring funds, modifying critical settings, or locking out legitimate owners. This could lead to total loss of assets and trust in the contract.

Improper Access Control

Property
Language	solidity
Severity
CWE	CWE-284: Improper Access Control
Confidence Level	Low
Impact Level	High
Likelihood Level	High

Description

A function in your smart contract allows anyone to call selfdestruct, which can permanently delete the contract and send its funds to an arbitrary address. This function lacks access control, so unauthorized users can trigger it.

Impact

If exploited, any user could destroy the contract, making all its code and data inaccessible and irreversibly transferring any remaining funds. This could result in total loss of assets and functionality for users and stakeholders.

Improper Access Control

Property
Language	solidity
Severity
CWE	CWE-284: Improper Access Control
Confidence Level	High
Impact Level	High
Likelihood Level	High

Description

The setMultipleAllowances() function lacks an onlyOwner modifier, meaning anyone—not just the contract owner—can call it. This allows unauthorized users to change allowances without proper permission checks.

Impact

If exploited, an attacker could grant themselves or others unauthorized allowances, potentially gaining control over funds or resources managed by the contract. This can lead to loss of assets, unauthorized transactions, and full compromise of the contract’s integrity.

Improper Authentication

Property
Language
Severity
CWE	CWE-287: Improper Authentication
OWASP	A04:2021 Insecure Design
Confidence Level	High
Impact Level	High
Likelihood Level	Medium

Description

The API uses HTTP Basic Authentication, which sends user credentials in an easily decodable format and lacks strong security protections. This approach is outdated and exposes sensitive information if intercepted.

Impact

Attackers could capture or reuse credentials through network sniffing or replay attacks, leading to unauthorized access to user accounts or system resources. This can result in data breaches, account compromise, and significant risk to both users and the organization.

Improper Authentication

Property
Language
Severity
CWE	CWE-287: Improper Authentication
OWASP	A02:2017 - Broken Authentication
Confidence Level	Medium
Impact Level	Medium
Likelihood Level	Medium

Description

The application’s Azure App Service is deployed without authentication enabled in the ‘auth_settings’ block. This means users can access the app without verifying their identity, leaving it open to unauthorized access.

Impact

Without authentication, anyone can interact with your application, potentially exposing sensitive data or critical functions to attackers. This could lead to data breaches, unauthorized changes, or abuse of your cloud resources, putting your organization at significant risk.
