TURNING THE VALVE - EXPLOITING RCE AND LPE IN THE STEAM PLATFORM

Atredis researchers found four local privilege escalation flaws and two remote code execution bugs in Steam for Windows. The LPE paths abused Steam's SYSTEM service through install-script allowlists, module loading, secure-desktop input forwarding, and driver installation. The remote bugs affected Steam-to-Steam synchronization messages: stack overflows in download-schedule and app-status handlers, plus an uninitialized-memory leak of steamclient64 pointers. The researchers combined the leak with an overflow to build a zero-click RCE using a ROP chain. They reported the issues to Valve through HackerOne. The bugs are patched or past the disclosure timeline, and proof-of-concept code is public.

HOW WE TOOK OVER CHATGPT ACCOUNTS

Researchers at Parameter Labs discovered a complex attack chain that could let attackers create malicious pages using ChatGPT's HTML Previews (formerly Canvas). The exploit begins by using the MathLive JavaScript library to create a new iframe that could load scripts from YouTube despite OpenAI's CSP policy. That iframe could then use YouTube's oEmbed endpoint to access OpenAI API endpoints and steal private data from anyone who accesses the ChatGPT share URL.

SECURING INTERNET CRITICAL SOFTWARE: HOW WE COULD HAVE BACKDOORED BASH

Researchers at Hacktron discovered a command injection vulnerability in GNU Savannah that let them gain root and take over user accounts, including a Bash maintainer. The vulnerability stemmed from the GPG key validator inserting a user's email address directly into commands it executed without sanitizing the input. The attackers utilized this vulnerability to install a webshell, read the database password, set their account to a superuser, impersonate other users, and also escalate privileges by exploiting GemOver(lay).
