WebKit parseFloat() type confusion leading to stack buffer overflow

Credits

• Zuk Avraham
• TODO

Bug Description

When inserting NaN with a parameter as an argument into parseFloat(), we can overflow the tiny buffer created by parseFloat().

Analysis

• WebKit PoC for PS3 released by xerpi through zecoxao in Playstationhax.xyz forum (2016-03-24)

Implementation

• PS3HEN on PS3 by the PS3Xploit team
• Writeup and PoC on Android 2.1 by Zuk Avraham

Patched

Patched on PS3 FW 4.83. Remains exploitable on higher firmwares by installing old WebKit sprx files in hybrid PUP.

WebKit CSS font face source type confusion leading to read primitive

Credits

TODO

Bug Description

While parsing the source of a CSS font face, CSSParser::parseFontFaceSrc() assumes the value given is a string, but if we insert a specific double value into an exploitable function like insert() or format(), we can leak the memory via an overlap between two variables.

Implementation

• PS3HEN on PS3 by the PS3Xploit team
• [1] initial bug report

Leakage of PTCH body plaintext over SPI on all BGA SYSCONs

When reading the body via the EEPROM read command, in all cases, the MISO of the SPI will leak the plaintext of the PTCH body to someone who might be interacting with the EEPROM interface. Note that this ONLY happens when SC interacts with patch body and some specific areas.

Examples

Lv2 sys_fs_mount stack overflow

Stack buffer overflow with required privileges when passing a length greater than 10. It now checks for length less than or equal to 10. If larger than 10, the length gets set to 10.

• writeup
• code

Patched: sometime before 4.40 (only fw I checked)

RSX Syscall bug

In most syscalls sony reduces a pointer to 32 bits and would use a special function to write to that pointer.
however, in certain rsx syscalls, sony forgot about it, allowing the attacker to write to any part of lv2 memory.

Patched: 4.40

Lv2 sys_prx_register_module stack overflow

Stack buffer overflow which is fixed around 4.3x or 4.4x. Does not require any privileges.

Lv2 578 Syscall stack overflow

Stack buffer overflow which is fixed around 4.3x or 4.4x. Requires root privileges. Syscall is compiled with stack cookies.

Patched: 4.4x

AES CTR vulnerability on SELFs (and ebootroms maybe?)

Sometimes SCE reused the same AES CTR keys and IVs in different Certified Files.

See also [6].

See also [7].

Patched: since some PS Vita prototype FWs as their Certified Files started having always different IVs.

Maybe not patched on PS3 ebootroms.

PARAM.SFO stack-based buffer overflow

• [8]

Patched: since 2012-05-01 (4.40 and later)

Proof of Concept

Unsigned code can be added to the PARAM.SFO because the console does not recognize special characters.

• [9]

Working on 4.31. Patched: since 2012-05-01 (4.40 and later).

PoC: PARAM.SFO

It is not a bug! It is a scekrit feature!

Renesas verify function works on 4 byte values in All renesas/nec SysCon chips

All NEC/Renesas syscon chips have their verify function working for a 4 byte array but 256 byte size, increasing the probability of finding the correct bytes as opposed to the intended 256 bytes.

(Universal) Renesas checksum function works on 256 byte values (ALL SYSCON CHIPS, stock, PSP, PS Vita, PS3, PS4)

Renesas checksum feature works on 256 byte values instead of the intended block size, which means glitching could be done in a narrower margin, making the efforts a lot easier. it is also possible to identify 256 byte constants contiguous to each other by their checksums.
