dark spirit invaders ( PushRequestAllowBreakInTarget).This means that the attacker can target anyone who joins their online session. The exploit is transmitted through matchmaking push requests containing NRSessionSearchResult information. The distribution vectors are what make this particular RCE particularly serious (beyond already being an RCE). From there a series of code redirections via virtual calls with different offsets (which will now jump at whatever addresses we wrote into the packet buffer) can be used to achieve arbitrary code execution. Clever exploitation of the DLMemoryInputStream object's structure and data size field then allows one to achieve arbitrary code redirection, with RCX pointing to the address of our packet. The stack overflow allows one to overwrite the lower two bytes vftable_ptr of the DLMemoryInputStream object used internally by the stream reader, redirecting execution to carefully chosen neighboring code. Improper bounds checking on a stack buffer and data size field during the parsing of NRSessionSearchResult matchmaking data allows an attacker to execute arbitrary code. Bug #2: Buffer Overrun in NRSessionSearchResult Parser.Bug #1: No Bounds Check in Entry List Parser.The General Exploitation Tactic for All Games.Since FROM SOFTWARE had not yet acted over 40 days after my initial report with proof of concept videos and detailed exploit documentation (which a large part of this readme is based on), I decided to demonstrate the existence of the exploit puclicly in a benign manner in the hopes of raising attention to have it addressed by the developers, and it worked. With the game having an average concurrent playerbase of about 20,000 players in the months preceding the server shutdown, it was clearly an issue that needed fixing immediately, especially with the possibility of it being in Elden Ring. ![]() In Dark Souls III, A malicious attacker abusing this would have been able to reliably execute a payload of up to 1.3MiB 1 of shellcode on every online player's machine within seconds. It is related to the matchmaking server and thus much more severe, since you do not need to partake in any multiplayer activity to be vulnerable due to another matchmaking server vulnerability (CVE-2022-24125). Dispelling MisconceptionsĬontrary to popular belief, this is NOT a peer-to-peer networking exploit. Kudos to LukeYui for compiling this list and to FROM SOFTWARE for acting swiftly! I'm happy to say that Elden Ring is undisputably the safest FROM SOFTWARE title when it comes to the extent of the damage hackers can inflict. In fact, a huge list of network crashes, out-of-bounds reads/writes and exploits allowing players to modify the game data of peers which were present in Dark Souls III have been patched in Elden Ring. While the closed network test was affected by this, the release version of Elden Ring is not. ![]() Presence in Demon's Souls has not been confirmed but is very likely. The vulnerable code is also present in Sekiro (credit: LukeYui), although there is no way to trigger it. Dark Souls 3 (up to 1.15.0) (credit: tremwil).Dark Souls 2 (including Scholar) (credit: LukeYui).Dark Souls Remastered (credit: metal-crow). ![]() As of now proof of concept code only exists for Dark Souls III, the vulnerability has been confirmed to be present in: While theoretically possible in other games, focus is on Dark Souls III as this is the game my research has been conducted on. This repository contains proof of concept code and documentation for the most recent RCE exploit affecting FROM SOFTWARE games, CVE-2022-24126. "curse knife") which could be encountered often during online multiplayer have also been patched. ![]() Furthermore, all known exploits allowing one to corrupt the save of other players have been fixed. This update fixed both CVE-2022-24125 and CVE-2022-24126, along with a wide variety of other potential security vulnerabilities present in the game's P2P networking (OOB reads/writes). I remember seeing a video when the game was fairly new of a hacker flying around the highwall firing greatarrows rapidly from a long bow and some how skipping the animations for drawing and firing each arrow.A new game update, 1.15.1, has been released for Dark Souls III on 5, along with the restoration of online services. The first is, how do i modify a bow/gbow/crossbow to fire rapidly? I know i can increase the speed of the player character but that's not what i mean. There's three things i need help with, if anyone wouldn't mind.
