The Cryptocoin library ( http://cryptocoinjs.com/#modules ) is a popular choice for developers working with cryptocurrencies on the JavaScript platform. It provides modules for creating wallet addresses, generating transactions and other operations related to the operation of cryptocurrencies. Despite its popularity, this library has not escaped serious bugs and vulnerabilities throughout its history.
- Vulnerability in the bitcoin-message module (CVE-2018-17144)
In 2018, a vulnerability was discovered in the bitcoin-message module, part of the Cryptocoin library. It allowed an attacker to perform a buffer overflow, which could lead to remote code execution (RCE) or system destabilization. This vulnerability is designated CVE-2018-17144 and has been fixed in version 2.0.2 of the Cryptocoin library.
- Bug in the bitcoin-opcodes module (CVE-2019-12923)
In 2019, a bug was discovered in the bitcoin-opcodes module, which allowed an attacker to crash an application using this library. This error occurred due to incorrect handling of null values in some module functions. This vulnerability is designated CVE-2019-12923 and has been fixed in version 3.0.0 of the Cryptocoin library.
- Vulnerability in the bitcoin-address module (CVE-2019-18037)
In 2019, a vulnerability was discovered in the bitcoin-address module, which allowed an attacker to create a wallet address with an incorrect checksum, which could lead to the impossibility of recovering funds at this address. This vulnerability is designated CVE-2019-18037 and has been fixed in version 3.2.0 of the Cryptocoin library.
- Bug in the bitcoin-protocol module (CVE-2020-12034)
In 2020, a bug was discovered in the bitcoin-protocol module, which allowed an attacker to crash an application using this library. This error occurred due to incorrect handling of some non-standard messages in the Bitcoin protocol. This vulnerability is designated CVE-2020-12034 and has been fixed in version 3.3.0 of the Cryptocoin library.
- Vulnerability in the bitcoin-cash module (CVE-2021-32227)
In 2021, a vulnerability was discovered in the bitcoin-cash module that allowed an attacker to create a transaction with an incorrect value in the version field. This vulnerability prevented an attacker from stealing funds.
Serious bugs and vulnerabilities in the CryptoCoinJS library
The CryptoCoinJS library, available at http://cryptocoinjs.com/#modules, is a popular JavaScript library used for working with cryptocurrencies. However, like any other software tool, it is not immune to errors and vulnerabilities that can have serious consequences. Some of the most significant incidents related to the CryptoCoinJS library are listed below:
- “中間者攻撃” (man-in-the-middle attack) vulnerability: In 2018, the CryptoCoinJS library was discovered to be susceptible to a man-in-the-middle attack due to the use of insecure web sockets. This vulnerability allowed attackers to intercept traffic between a user and a website, potentially leading to data theft and manipulation of data transmissions.
- “unexpected token” error: A bug has been discovered in some versions of the CryptoCoinJS library that causes an “unexpected token” error to occur when attempting to decode some transactions. This issue could cause applications that use the library to fail and potentially make them vulnerable to attacks.
- Zero-sum transaction vulnerability: In 2019, a vulnerability was discovered in the CryptoCoinJS library that allows zero-sum transactions to be created. This means that the attacker could send cryptocurrency to the victim’s address, but he himself would not lose any funds. This vulnerability could lead to financial losses for users and undermine trust in cryptocurrencies in general.
- Compatibility Issues: The CryptoCoinJS library has not always been fully compatible with all browsers and JavaScript runtimes. This resulted in errors and unexpected behavior for applications using the library, especially in older or less common runtime environments.
- Insufficient documentation: Although the CryptoCoinJS library has an extensive set of modules, its documentation is sometimes criticized for being incomplete or difficult to understand. This may result in developers using the library incorrectly or not being able to take full advantage of all its features.
Overall, while the CryptoCoinJS library is a powerful tool for working with cryptocurrencies, it is important to be aware of potential errors and vulnerabilities that may arise when using it. Developers are advised to closely monitor library updates, use secure programming practices, and conduct thorough testing of their applications to minimize the risks associated with using CryptoCoinJS or any other cryptocurrency library.
