02ATTACKS & VULNERABILITIES

EDUCATION GIANT PEARSON HIT BY CYBERATTACK EXPOSING CUSTOMER DATA

Pearson has reported that an attacker breached its systems and stole “legacy” data. Other sources revealed that the stolen data was obtained via an exposed .git/config file containing a GitLab Personal Access Token (PAT), which was used to obtain hardcoded secrets for cloud platforms and data stores from source code. The stolen data allegedly contains customer information, financials, support tickets, and source code.

CISCO FIXES MAX SEVERITY IOS XE FLAW LETTING ATTACKERS HIJACK DEVICES

Cisco has released fixes for a maximum severity (10.0 CVSS score) vulnerability affecting IOS XE Software for Wireless LAN Controllers. The devices utilize a hardcoded JWT that could allow unauthenticated attackers to exploit the AP image download interface to upload files, perform path traversal, or execute arbitrary code. Only devices with the “Out-of-Band AP Image Download” feature, which allows APs to download AP's OS images via HTTPS, are vulnerable.

PHISHING DESPITE FIDO, LEVERAGING A NOVEL TECHNIQUE BASED ON THE DEVICE CODE FLOW

Enforcing FIDO as the sole MFA is often seen as phishing resistant. However, this post shows a new attack that utilizes the OAuth 2.0 Device Code Flow to downgrade MFA. The Device Code Flow enables a user to authenticate devices. In this method, an attacker uses a headless browser to automate the Device Code Flow, allowing the user to be phished through an attacker-controlled link without entering the code.

DRAG AND PWND: LEVERAGE ASCII CHARACTERS TO EXPLOIT VS CODE

Zakhar Fedotkin found that ASCII control characters such as SOH (\x01) and ETX (\x03) can be exploited in Visual Studio Code to run arbitrary commands via node-pty, which sends raw bytes to the shell. The vulnerability exploits two vectors: injecting control characters into run configuration files and creating maliciously named files that execute commands when dragged into VS Code's terminal. This issue impacts macOS and Ubuntu systems, where control characters are permitted in filenames, although Microsoft does not view it as a security vulnerability due to measures like workspace trust warnings.
