A high-severity security flaw has been disclosed in the open source jsonwebtoken (JWT) library that, if successfully exploited, could lead to remote code execution on a target server. “By exploiting this vulnerability, attackers could achieve remote code execution (RCE) on a server verifying a maliciously crafted JSON web token (JWT) request,” Palo Alto Networks Unit […]
Web application firewalls, also known as WAFs, are intended to protect web-based applications and application programming interfaces (APIs) from malicious HTTPS traffic coming from the outside, particularly cross-site scripting and SQL injection attacks, which never seem to fall off the security radar. SQL injection in particular is a constant among the output of automated code […]

JSON is a method for representing arbitrary JavaScript data types as a string safe for HTTP communications. For example, a web-based email site might use JSON to retrieve messages or contact lists. Other sites use it to send and receive commands and data from databases. In 2006 Gmail had a very interesting cross-site request forgery […]
PyJFuzz is a small, extensible and ready-to-use framework used to fuzz JSON inputs , such as mobile endpoint REST API, JSON implementation, browsers, cli executable and much more.

Benjamin Dumke-von der Ehe found an interesting way to steal data cross domain. Using JS proxies he was able to create a handler that could steal undefined JavaScript variables. This issue seems to be patched well in Firefox however I found a new way to enable the attack on Edge. Although Edge seems to prevent […]
