In today’s rapidly evolving technology landscape, application security is becoming a priority. New vulnerabilities in popular packages are frequently discovered, posing significant threats to our projects. Therefore, it’s essential to stay updated with the latest security discoveries and know how to effectively protect against them. In this article, we present six recently detected vulnerabilities by Sequrify.
One of the detected vulnerabilities is filename spoofing in the Archive package, version 3.3.7. This vulnerability allows attackers to spoof ZIP file names, leading to severe security issues. The problem lies in the Archive package analyzing the file name only from the local file header, which leads to inconsistencies with most ZIP parsers that prefer central directory entries. Attackers can create a malicious ZIP file with different file names in the local header and central directory, causing the file to have different names before and after extraction.
Another significant vulnerability is CRLF injection in the dio package for Dart. This vulnerability allows attackers to inject malicious instructions into HTTP requests, leading to web request manipulation and the injection of malicious scripts executed in the user’s browser. This issue occurs when an application allows users to input their HTTP request method, and this data is not properly validated.
Another vulnerability affects the Archive package, version 3.3.7, enabling attackers to perform path traversal attacks. Path traversal is an attack technique that allows access to files and directories outside intended locations. In the case of the Archive package, this vulnerability allows attackers to extract a malicious ZIP file in a way that writes files to unauthorized locations on the disk, potentially leading to data theft.
The next vulnerability was detected in the personnummer package for Dart, which is used for validating personal numbers. The issue lies in improper input validation, allowing attackers to input specially crafted data that passes the validation process despite being incorrect. This can lead to storing invalid data in the system, which can have serious consequences.
Another vulnerability affects the HTTP package for Dart, allowing attackers to inject malicious data into HTTP headers. If an application improperly validates or sanitizes input data used to create HTTP headers, it can lead to malicious data injection, resulting in HTTP request forgery and user session hijacking.
The last discussed vulnerability involves PubNub and relates to insufficient entropy when generating cryptographic keys. Low entropy allows attackers to predict or guess future keys, enabling access to private communications or data. To protect against this vulnerability, use strong random generators that provide high entropy and implement monitoring mechanisms to detect and respond to potential attack attempts.
Application security is a priority, and regular updates, input validation, and conscious dependency management are key steps in protecting against potential threats. By using tools like Sequrify, you can significantly increase the level of protection and trust in your products. Let’s act proactively to ensure the highest level of security for our users.
