Logical Issue (Boosting Reputation points)
How it was found
Hello,
This bug is a design flaw in the reputation system.
Simply, when a bug is resolved +7 is added to the user's account. When bounty is awarded then the reputation points are calculated based on standard deviation from the program's mean.
I found these here ---> https://hackerone.com/news/introducing-reputation
You gain reputation when: Your report is Closed as Resolved: +7 Your report is Closed as Duplicate (Resolved): +2. Only applied if reported before the original was closed. You are awarded a bounty. The amount is based on standard deviation from the program's mean: +50: $ >= µ + 1σ +25: $ > µ +15: $ >= µ - 1σ +10: $ < µ - 1σ Your report is Closed as Won't Fix: +1 Your report is Closed as Duplicate (Won't Fix): +1
You lose reputation when: Your report is Closed as Not Applicable: -5 Your report is Closed as Duplicate (Not Applicable): -5 Your report is updated as Needs more info: -1
- Now, one reporter can earn max of
+50reputation points if award is far maximum than program's min bounty amount. - Also, when report is marked as
Resolvedthen+7are added. - So, totally max of
+57points can be made from a single bug report.
But there exists a flaw which will allow to boost reputation points more than +57.
- A report is awarded bounty of
$350but minimum bounty of program is$100. So, this adds+50reputation points to the reporter. - Now, report is marked resolved, so
+7reputation points are added. - Now, if same report is awarded with bounty
$150, then it will again add+15.
So, if a report is rewarded again and again then it will boost reputation points more than default +57. So, this totally contradicts the policy mentioned here ---> https://hackerone.com/news/introducing-reputation
Due to this flaw, reporter will earn more reputation points more than other researchers.
i.e If researcher two reports a severe bug then he will get +50 and +7. Total of +57. (Total bounty 1000$)
But at the 1st researcher's report is being rewarded again and again. It will boost as +50 and +7 and again awarded so +15. Total +72.(Total bounty 350$ + 150$ = 500$)
I hope you understand the severity here and modify the reputation system accordingly. I found this bug on my own account. So, I am attaching an image poc of my account. Sensitive information has been forged.
