PS4 firmware 7.55 exploit revealed by TheFlow

ps4-logo-png.216379
An exploit for the PS4's firmware 7.55 was revealed today by hacking scene member TheFlow. However, it was actually reported back in June 2020 and disclosed only today as TheFlow worked with Sony's HackerOne bounty program to patch this vulnerability. The reported exploit was marked as resolved in October. TheFlow also did similar disclosures with previous exploits he found and helped fix.

The HackerOne page notes that this vulnerability can cause a "fully chained remote attack" when used with a WebKit exploit, steal/manipulate user data and even dump and run pirated games. As such, it could be used together with the Webkit exploit from last December to jailbreak PS4 systems on firmware 7.55. However, no relevant files have been made publicly available regarding the FW 7.55 exploit with today's disclosure.

I remember someone installing Windows 10 and running Steam games on the system, but couldn't tell you how well those games, if any at all, ran.

I already have an exploitable system (that I paid through the nose for). What I care about are people just getting into the scene who could have gotten any cheap used system or black Friday deal, who now have to scour the Internet in hopes of finding a rare, overpriced system that's under a certain firmware. It greatly increases the barrier to entry.

And that, ladies and gents, is why, as opposed to being like a Twitter mob, lashing out recklessly without letting the facts all come out, you wait, do your research, and try to get as full of a picture as you can before making decisions in life!

I understand what @CanIHazWarez is saying but from my personal experience this is a great thing that the Fl0w did disclose this information because there is hope of the PS4 being fully exploitable at the EOL. I had first hand experience with a jailbroken PS4 before I had sold it 3 years ago (5.05) it was a pain to get the games and it was more easier just buying them since they are dirt cheap.

Also FYI it is NOT easy to find a exploitable PS4 for cheap because a good percantage of people update their systems to the latest firmware. When you do go on ebay you have to shellout $300+ on old equipment the only good thing is hope you can find a new PS4 inside the box from GameStop that has 7.55 FW. (if you are lucky)

That's because it's usually a very old firmware by the time they release the exploit, but this time it is not that old and should be very easy to find a cheap system for the next few weeks at least.

I bought one cheap and sat on it for a couple of months until the exploit came out, if you must wait and then want it straight away then I guess you pay a premium.

To be very honest with you if a new system from GameStop is on 7.55 or below I rather buy new versus used... but again idk what firmware is on the new ones at GameStop or Walmart. 7.55 is pretty old the only people who would have that are people who missed out on 5.05, or 6.72. I would be very interested in getting a new one if it is on low firmware.

Funny thing I actually bought one for $325 3 years ago but at the time I couldn't get the games for it or understood it was locked on 5.05 so I had sold it. I sometimes regret doing it but at the time the scene was moving so slow and it was on 5.05 firmware for a while. I wouldn't buying one again considering 7.55 firmware has alot of games on it. Most my jailbroken devices I buy on ebay and I never had a problem with it however it depends on the person that had the item before you.

Both of my CFW switches came from ebay in top condition.
