Usermode

BD-J exploits

FW <= 7.61 - BD-JB2 - Path traversal sandbox escape by TheFloW

See [1].

Patched

Yes on PS5 FW 8.00.

FW <= 4.51 - BD-JB - Five vulnerabilities chained by TheFloW

See [2].

Implementations

• PS5 BD-JB implementation by Antonio Jose Ramos Marquez (psxdev)
• PS5 BD-JB implementation by John Törnblom
• PS5 BD-JB implementation by sleirsgoevy
• PS5 BD-JB implementation by TheFloW

Patched

Yes partially on PS5 FWs > 4.50 (need to test). Probably unpatched on FW 4.51 and patched on FW 5.00.

WebKit exploits

Contrarly to PS4, on PS5 WebKit exploit usually do not allow arbitrary RW to usermode code sections because of PS5 memory protections (notably XOM). However thanks to leaks of usermode libraries .text section binaries, by other sort of vulnerabilities, and to RW access to WebKit .data section allowed by the WebKit exploit, it is possible to trigger usermode ROP code execution.

Modal Browser HTTPS Bypass

• It is possible to bypass HTTPS in the modal browser, if you reply to the HTTPS CONNECT with a standard HTTP 1.1 response, instead of attempting to create a tunnel. The web browser will just display that response. The downside to this is that you have no idea of what the contents of even the HTTP REQUEST would have been, but it is useful for redirecting the web browser to any website you want.

Patched

No as of PS5 FW 5.10.

Untested - mmap issue involving pointer address misalignment leading to nothing for now

Credits

Analysis

• https://bugs.webkit.org/show_bug.cgi?id=246763

Bug Description

There is a mmap issue involving pointer address misalignment because of a failing assert here. A workaround is to set HAVE_MAP_ALIGNED flag as OFF in OptionsPlayStation.cmake: [4]. This workaround can be reverted after the mmap issue is resolved. Currently, the workaround is still enabled: [5]

OptionsPlayStation.cmake is present in the PS4 11.00 OSS WebKit source code but does not contain the HAVE_MAP_ALIGNED flag, and according to dates, this might concern only the PS5.

Physical memory readable by kernel (Meme Dumper)

Credits

Discovered by cheburek3000. Released on 2023-02-07 by cheburek3000.

Bug Description

Steps:

1. Find kernel_pmap_store offset in kernel data segment. You can guess its location by specific signature (see guess_kernel_pmap_store_offset code). Luckily kernel_pmap_store has physical and virtual addresses for PML4.

2. Through physical and virtual addresses for PML4, you can find physical memory mapped directly to the kernel memory (DMAP). See PADDR_TO_DMAP macro and vmparam.h from FreeBSD for reference.

3. Use page tables to convert any kernel virtual address to physical address (see vaddr_to_paddr code).

4. Access data by physical address through DMAP.

• Exploitation strategy explanation by Specter (2024-09-21)

Bug Description

The _umtx_op(2) system call provides support for the implementation of synchronization primitives between threads, and is used by the 1:1 Threading Library (libthr, -lthr) to implement IEEE Std 1003.1-2001 (POSIX.1-2001) pthread locks, like mutexes, condition variables and so on. In particular, its UMTX_OP_SHM operation provides support for anonymous shared memory associated to a particular physical address, which is used to implement process-shared mutexes (PTHREAD_PROCESS_SHARED).

Concurrent removals of such a mapping by using the UMTX_SHM_DESTROY sub-request of UMTX_OP_SHM can lead to decreasing the reference count of the object representing the mapping too many times, causing it to be freed too early.

umtx_shm_unref_reg_locked() would unconditionally drop the "registry" reference, tied to USHMF_LINKED.

This is not a problem for caller umtx_shm_object_terminated(), which operates under the 'umtx_shm_lock' lock end-to-end, but it is for indirect caller umtx_shm(), which drops the lock between umtx_shm_find_reg() and the call to umtx_shm_unref_reg(true) that deregisters the umtx shared region (from 'umtx_shm_registry'; umtx_shm_find_reg() only finds registered shared mutexes).

Thus, two concurrent user-space callers of _umtx_op() with UMTX_OP_SHM and flags UMTX_SHM_DESTROY, both progressing past umtx_shm_find_reg() but before umtx_shm_unref_reg(true), would then decrease twice the reference count for the single reference standing for the shared mutex's registration.

A malicious code exercizing the UMTX_SHM_DESTROY sub-request in parallel can panic the kernel or enable further Use-After-Free attacks, potentially including code execution or Capsicum sandbox escape.

FW <= 4.03 - exFAT driver heap-based buffer overflow

See the PS4 wiki.

Credits

Discovered by TheFloW. Disclosed by ChendoChap.

Exploit Implementation

Edit: it may now be possible to build a valid PS5 exFAThax payload thanks to PS5 kernel .text segment dumps for System Software versions <= 2.70 thanks to Hypervisor exploits.

Not yet because even though there is ChendoChap's method to execute usermode code in WebKit, there is no PS5 kernel .text segment dump to build a kernel ROP chain. Exploiting this kernel vulnerability blind is almost impossible because once the USB device is inserted it corrupts the kernel heap memory and if the offsets in the kernel ROP chain are bad it creates a kernel panic.

Patched

Yes in PS5 FW 4.50.

• FreeBSD advisory for CVE-2021-29628 (2021-05-26)

Bug Description

In FreeBSD 13.0-STABLE before n245764-876ffe28796c, 12.2-STABLE before r369857, 13.0-RELEASE before p1, and 12.2-RELEASE before p7, a system call triggering a fault could cause SMAP protections to be disabled for the duration of the system call. This weakness could be combined with other kernel bugs to craft an exploit. It does not work on PS4 because PS4 kernel is based on FreeBSD 9 which did not contain the vulnerability and because PS4 SMAP does not come from FreeBSD but is custom from Sony. It used to work on PS5 before it was disclosed and patched.

Patched

Yes in PS5 FW 2.30 or later according to dates.

Kernel securities

dlsym syscall removed

Since PS5 System Software version 5.00, dlsym syscall is disabled (?removed?). dlsym could be used to resolve functions and variables addresses by their name. This was convenient for multi-firmware support.

Workaround: in the same way as in PSP and PS Vita HBL, and vitasploit, a workaround is to resolve functions by per-version offsets manually.

MAP_SELF flag removed

Since PS5 System Software version 5.00, MAP_SELF flag is nonexistent. MAP_SELF flag could be used for decrypting PS5 usermode SELFs such as eboot.bin and SUPRXs for games and applications, and system SELFs from /system and /system_ex, etc.

Workaround: using the PSP functions directly like Specter does.

Secure Kernel

Untested: Partial SAMU KeyRings bruteforce by missing HMAC length check in secure kernel

See [16].

Potentially vulnerable on PS5 FWs <= 4.03.

Hypervisor

Without a Hypervisor bypass/compromise, you are essentially limited to "data-only" attacks in kernel and usermode. Since patching the kernel is the most straightforward and direct way to achieve true homebrew on the PlayStation 5, bypassing or compromising the PS5 Hypervisor is necessary. Getting code execution in the PS5 Hypervisor allows one to dump and modify kernel .text segment, and to disable some protections. Moreover, chained with a higher level vulnerability, Hypervisor code can dump AMD PSP memory.

<=?2.70? - APIC pointers in kernel data segment

Credits

• Discovered by flatz. Disclosed publicly by flatz (2024-10-09).

Bug description

The apic_ops structure is located in the PS5 kernel .data segment which has RW permissions. Using a kernel vulnerability, you can overwrite a function pointer inside the apic_ops structure, like xapic_mode. This allows to launch a ROP chain but one has to bypass the CFI protection. After doing a PS5 suspend/resume cycle, the ROP code will be executed before Hypervisor restarts. The ROP chain can apply patches in kernel .text section.

<=2.70 - System Level debug flag in kernel data segment and not wiped after rest mode (Byepervisor bug #2)

Credits

• Discovered by Specter and ChendoChap (2023-07-01, Specter's announcement).
• Disclosed publicly by Specter at Hardwear.io 2024 conference (2024-10-24).

Bug description

On PS5 System Software version 2.70 and lower, the System Quality Assurance (QA) flags are shared between the Hypervisor and the guest kernel. When the hypervisor initializes, the init code for constructing nested page tables will check QA flags for the System Level (SL) debugging flag. If this flag is set, the nested Page Table Entries (PTEs) will not have the xotext bit set for kernel .text pages, and further the kernel .text pages will also have the write bit set.

These flags are not reinitialized by the Secure Loader upon resume from PS5 sleep mode, though the hypervisor is. By setting the SL flag, then putting the system to sleep and resuming, we can edit the guest kernel's page tables to make kernel .text pages readable and writable, allowing kernel dump and patches.

• Disclosed publicly by Specter at Hardwear.io 2024 conference (2024-10-24).

Bug description

On PS5 System Software version 2.70 and lower, the Hypervisor's Hypervisor#Hypercalls virtual tables are shared with the guest kernel. It is possible to hijack some entries (for example VMMCALL_HV_SET_CPUID_PS4) in the hypercalls virtual table to jump to a ROP chain. On System Software version 2.70 and lower, this virtual table is stored in the kernel .data segment. By using two ROP chains, one for setting up hypervisor registers and one for executing code in hypervisor. Indeed, the registers used by the Hypervisor are preserved accross Virtual Machine exit boundary. The ROP chain disables Nested Paging (NPT) and Guest Mode Execute Trap (GMET), which allows us to disable eXecute Only Memory (XOM) aka xotext in the kernel Page Table Entries (PTEs) to dump it, as well as enabling write in the PTEs to hook/patch the kernel as well.

This method requires a fair number of gadgets and offsets, which is the main reason this exploit is deprecated over the Byepervisor bug #2. This method also currently only breaks the hypervisor on the core the ROP chain runs on. The hypervisor is still active on other cores and would need to be disabled.

Bug description

Secure Loader (software) - AMD Platform Security Processor (hardware)

• The PS5 APU is a custom AMD ZEN 2 Ryzen chip that includes the AMD Platform Security Processor and the AMD SMU.

• The AMD Platform Security Processor runs the Secure Loader that is in charge of loading and executing Secure Modules, like on PS4. The Secure Loader exports some SM management services to kernel through a mailbox.

• With a Hypervisor exploit, it is possible to exploit a vulnerability to dump the AMD Platform Security Processor memory. This dump contains the PS5 Secure Loader. This leads to PS5 symmetric root keys dump, that can then be used for decryption of most Secure Modules. This allows to decrypt on PC most parts of the PS5 System Software files (see also PS Vita 0xAA key fail impact) including:
• Secure Modules
• PUP
• kernel boot loader / BIOS
• non-secure Kernel
• usermode system modules

<=2.70 - Software vulnerability leading to Secure Loader dump from Hypervisor

Credits

• Discovered by Shawn Hoffman (shuffle of fail0verflow) before 2021-09-08 and announced on 2021-11-08 (Fail0verflow's announcement on Twitter (2021-11-08))
• Discovered independently and announced on 2023-07-27 by flatz (flatz's announcement on Twitter (2023-07-27)).

Bug description

A software vulnerability triggered from the PS5 Hypervisor leads to AMD Platform Security Processor memory dump.

It must be noted that Shawn Hoffman (fail0verflow, Microsoft Offensive Security Research) reported in 2020, 2021 and 2022 many vulnerabilities affecting AMD Security Processor (ASP), AMD System Management Unit (SMU), AMD Secure Encrypted Virtualization (SEV), and other AMD platform components.

From AMD Server Vulnerabilities – November 2021: CVE-2021-26315, CVE-2021-26335, CVE-2021-26336, CVE-2021-26337, CVE-2021-26338, CVE-2021-26351, CVE-2021-26352.

The most probable vulnerabilities that could have been used are:

• CVE-2021-26315 6.9 (Medium): A CPU internal ROM improperly implements decryption of signed off-chip firmware. An attacker with physical access or high privileges could potentially exploit this vulnerability leading to the execution of arbitrary code on the PSP, compromising the authenticity of the attestation state. -> Note that flatz stated that he used only software, including Hypervisor code execution, but not hardware for his exploit, so it is the "attacker with high privileges" part that might be concerned.
• CVE-2021-26335 7.5 (High): Improper input and range checking in the AMD Secure Processor (ASP) boot loader image header may allow an attacker to use attacker-controlled values prior to signature validation potentially resulting in arbitrary code execution. -> This reminds of the CMeP vulnerability about SLSK header parsing found by Team Molecule for PS Vita.
• Other Shawn Hoffman's CVEs are related to the AMD System Management Unit (SMU) but mainly to trigger Denial of Service and it is not clear how AMD SMU could be used to dump AMD PSP's memory.

From AMD Server Vulnerabilities - May 2022: CVE-2021-26347, CVE-2021-26350, CVE-2021-26372, CVE-2021-26373, CVE-2021-26375, CVE-2021-26376, CVE-2021-26378

These CVEs are mostly related to AMD SMU, not AMD PSP, and trigger Denial of Service but not Information Leak nor Code Execution.

From AMD Client Vulnerabilities – May 2022: CVE-2021-26335, CVE-2021-26336, CVE-2021-26337, CVE-2021-26347, CVE-2021-26350, CVE-2021-26351, CVE-2021-26352, CVE-2021-26372, CVE-2021-26373, CVE-2021-26375, CVE-2021-26376, CVE-2021-26378

These AMD Client CVEs are already listed in the 2021 and 2022 AMD Server Security Bulletins.

EMC, EFC and EAP vulnerabilities leading to code execution

Credits

• Disclosed by Shawn Hoffman (of SYMBRKRS LLC, @shuffle2 of fail0verflow) at the Security Analyst Summit Conference 2024 (2024-10-23).

Bug description

These exploits allow code execution on EMC, EFC and EAP. The exploits are interesting as they cover a hard-to-spot bug in a firmware state machine, and abusing hardware misconfiguration to bypass memory protection measures.

It is required to solder to Service Connectors to make use of these vulnerabilities.

<=?9.40? - TheFloW's neither usermode nor kernel vulnerability

• On 2024-08-29, TheFloW received 10.000$ from Sony for disclosing privately a vulnerability on Sony's HackerOne bug bounty program.

• According to Flatz, this vulnerability affects neither usermode nor kernel, so it might be about hardware (AMD PSP maybe) or still software but more likely about Hypervisor or Secure Loader or Secure Modules.
