PS5 Relapse Exploit

Supported firmware: 7.00 through 13.60.

Usage

• In the network settings, set Primary DNS to 45.56.67.85 (Recommended)
• Run python serve.py locally, or open https://ntfargo.github.io/Relapse-Exploit/ on the PS5.
• The default payloads are stored in payloads/ after a successful run, the ELF loader listens on port 9021.
• After elfldr starts on port 9021, the host auto-sends payloads/np-fake-signin-ps5.elf (no wait), then payloads/OnionHEN.elf (5s), then Instant Payload Manager payloads/pldmgr_v0.5.2-r2.elf (5s), then payloads/webkit-autoloader-installer_v0.5.2.elf (5s). payloads/shadowmountplus.elf is saved into /data/ps5_autoloader and sent after reboot, so it does not run while User Guide is open. Do not send kstuff/etaHEN first. Payload Manager is then at http://<PS5>:8084. Settings Autoload Delay includes Instant.
• OnionHEN auto-starts a built-in FTP server on TCP 1337.
• Leave http://127.0.0.1:18181/ open until the Autoloader install finishes, then reboot and open WebKit Autoloader. The Internet Browser PKG is kept.

Stability notes

Webkit may need several attempts, reload the page if the browser stalls. The kernel exploit may hang or panic the console, so reboot before trying again if that happens.

Exploit chain

Browser stage uses JSC info leaks and a structured clone object pool mismatch to corrupt a typedarray. The kernel stage combines a address leak with an aio_multi_wait uaf race to establish kernel r/w.
