All the vulnerabilities related to the version 1.3.6 of the package
Insecure Credential Storage in web3
All versions of web3 are vulnerable to Insecure Credential Storage. The package stores encrypted wallets in local storage and requires a password to load the wallet. Once the wallet is loaded, the private key is accessible via LocalStorage. Exploiting this vulnerability likely requires a Cross-Site Scripting vulnerability to access the private key.
No fix is currently available. Consider using an alternative module until a fix is made available.
Got allows a redirect to a UNIX socket
The got package before 11.8.5 and 12.1.0 for Node.js allows a redirect to a UNIX socket.
Denial of service while parsing a tar file due to lack of folders count validation
During some analysis today on npm's node-tar package I came across the folder creation process, Basicly if you provide node-tar with a path like this ./a/b/c/foo.txt it would create every folder and sub-folder here a, b and c until it reaches the last folder to create foo.txt, In-this case I noticed that there's no validation at all on the amount of folders being created, that said we're actually able to CPU and memory consume the system running node-tar and even crash the nodejs client within few seconds of running it using a path with too many sub-folders inside
You can reproduce this issue by downloading the tar file I provided in the resources and using node-tar to extract it, you should get the same behavior as the video
Here's a video show-casing the exploit:
Denial of service by crashing the nodejs client when attempting to parse a tar archive, make it run out of heap memory and consuming server CPU and memory resources
This report was originally reported to GitHub bug bounty program, they asked me to report it to you a month ago
min-document vulnerable to prototype pollution
A vulnerability exists in the 'min-document' package prior to version 2.19.0, stemming from improper handling of namespace operations in the removeAttributeNS method. By processing malicious input involving the proto property, an attacker can manipulate the prototype chain of JavaScript objects, leading to denial of service or arbitrary code execution. This issue arises from insufficient validation of attribute namespace removal operations, allowing unintended modification of critical object prototypes. The vulnerability remains unaddressed in the latest available version.
web3-core-method is vulnerable to prototype pollution
web3-core-method is a package designed to creates the methods on the web3 modules. A Prototype Pollution vulnerability in the attachToObject function of web3-core-method version 1.10.4 and before allows attackers to inject properties on Object.prototype via supplying a crafted payload, causing denial of service (DoS) as the minimum consequence.
web3-core-subscriptions has a Prototype Pollution vulnerability
The web3-core-subscriptions is a package designed to manages web3 subscriptions. A Prototype Pollution vulnerability in the attachToObject function of web3-core-subscriptions version 1.10.4 and before allows attackers to inject properties on Object.prototype via supplying a crafted payload, causing denial of service (DoS) as the minimum consequence.
