Is there a definition of ErrorEvent somewhere in the Angular docs? Another error from sentry reported as just [object Event] is from the. the official MyEtherWallet app MEW wallet is a true, non-custodial Ethereum wallet. This means that you and only you have access to your funds. The balance represents a value that is defined by the contract creator: one token contract might use balances to represent physical objects.

If the stack trace in utils. Denial of Service DoS describes a family of attacks, all aimed at making a system inaccessible to its original and legitimate users. There are many types of DoS attacks, ranging from trying to clog the network pipes to the system by generating a large volume of traffic from many machines a Distributed Denial of Service - DDoS - attack to sending crafted requests that cause a system to crash or take a disproportional amount of time to process. Regular expressions are incredibly powerful, but they aren't very intuitive and can ultimately end up making it easy for attackers to take your site down. But when given an invalid string, it takes nearly two seconds to complete the test, over ten times as long as it took to test a valid string. The dramatic difference is due to the way regular expressions get evaluated. Most Regex engines will work very similarly with minor differences. The engine will match the first possible way to accept the current character and proceed to the next one. If it then fails to match the next one, it will backtrack and see if there was another way to digest the previous character. While it seems fairly straightforward, there are still four different ways that the engine could match those three C's:. The engine has to try each of those combinations to see if any of them potentially match against the expression. When you combine that with the other steps the engine must take, we can use RegEx debugger to see the engine has to take a total of 38 steps before it can determine the string doesn't match. By the time the string includes 14 C's, the engine has to take over 65, steps just to see if the string is valid. These extreme situations can cause them to work very slowly exponentially related to input size, as shown above , allowing an attacker to exploit this and can cause the service to excessively consume CPU, resulting in a Denial of Service. Affected versions of this package are vulnerable to Prototype Pollution. The library could be tricked into adding or modifying properties of Object. Prototype Pollution is a vulnerability affecting JavaScript. Prototype Pollution refers to the ability to inject properties into existing JavaScript language construct prototypes, such as objects. An attacker manipulates these attributes to overwrite, or pollute, a JavaScript application object prototype of the base object by injecting other values. Properties on the Object. When that happens, this leads to either denial of service by triggering JavaScript exceptions, or it tampers with the application source code to force the code path that the attacker injects, thereby leading to remote code execution. Properties are then copied on the Object prototype. There are a few JavaScript libraries that use an API to define property values on an object based on a given path. The function that is generally affected contains this signature: theFunction object, path, value. Arteau, Oliver. Vulnerabilities 2 via 2 paths Dependencies Source npm. Find, fix and prevent vulnerabilities in your code. Test and protect my applications. Issues Dependencies. Severity Critical. Vulnerable module: mocha Introduced through: mocha 5. Remediation: Upgrade to mocha 6. Overview mocha is a javascript test framework for node. Details Denial of Service DoS describes a family of attacks, all aimed at making a system inaccessible to its original and legitimate users. From there, the number of steps the engine must use to validate a string just continues to grow. Remediation Upgrade mocha to version 6. Prototype Pollution. Vulnerable module: minimist Introduced through: mocha 5. Overview minimist is a parse argument options module. Property definition by path There are a few JavaScript libraries that use an API to define property values on an object based on a given path. DoS occurs when Object holds generic functions that are implicitly called for various operations for example, toString and valueOf. The attacker pollutes Object. In this case, the code fails and is likely to cause a denial of service. For example: if an attacker pollutes Object. Remote Code Execution Client Remote code execution is generally only possible in cases where the codebase evaluates a specific attribute of an object, and then executes that evaluation. For example: eval someobject. In this case, if the attacker pollutes Object. Property Injection Client The attacker pollutes properties that the codebase relies on for their informative value, including security properties such as cookies or tokens. For example: if a codebase checks privileges for someuser. Affected environments The following environments are susceptible to a Prototype Pollution attack: Application server Web server How to prevent Freeze the prototype— use Object. Require schema validation of JSON input. Avoid using unsafe recursive merge functions. Consider using objects without prototypes for example, Object. As a best practice use Map instead of Object. For more information on this vulnerability type: Arteau, Oliver. Prototype Pollution vulnerability report. This is the most likely attack. Remote code execution is generally only possible in cases where the codebase evaluates a specific attribute of an object, and then executes that evaluation. The attacker pollutes properties that the codebase relies on for their informative value, including security properties such as cookies or tokens. This is a very simplified version of how encryption works, but it gets the point across. The result is a file that looks a lot like gibberish if you open it, which there is no reason to do, do not open your JSON file! This file simply holds your encrypted private key within it, which is why you have to use your chosen password to unlock your wallet via this method. If you choose a weak password, and a hacker gets hold of your encrypted key, they can bruteforce it until they discover what password you used. Pick a strong password for a strong encryption! As mentioned above, you cannot change your password without generating a completely new JSON file. Step 1. Step 4. Step 6. Can I Change my Password? For more information on other methods of access, check out our article on how to access a wallet. Step 2. This does not mean generating an entirely new wallet. Step 3. Enter a strong password, and save the wallet. This will be the new password for your JSON file, so choose wisely. Step 5. Enter in the password you just made. Share to.
