Prototype Pollution research, performed with co-authorship by @_nikitastupin in Advanced Security Research team, is nominated to “Top 10 Web Hacking Techniques of 2021”. The opportunity for bug hunter, who found the research insightful, to support authors: https://t.co/HC1mSKAVk4

Payment systems are a tidbit for an attacker, but often it’s non-achievable scope for bug hunters outside the company. Bug bounty programs of financial organizations include resources that are on the surface of the attack, and it’s quite difficult for a researcher to dig deeper into the internal financial processes. So we have to limit ourselves with XSS, SSRF in a web-application of the payment system.
We discovered two more JS Prototype Pollution vulnerabilities in one more nmp-package: CVE-2020-28449, CVE-2020-28450. The package has ~200 weekly downloads, so the popularity level is limited. However, due to the patch is still unavailable check the details and make sure that your Node.js app is not affected.
Quick summary of Bug Hunting Village, the first time we organized offline:
- 12 talks and workshops focused on vulnerability research and bug bounty;
- highest payouts during two days of conference by our partners (thanks to Mail.ru Group, VK.com, Азбука Вкуса, Avito, iSimpleLab);
- prizes for most active bug hunters (thanks to PHDays organizers and Timur Yunusov);
- communication in our Chat and knowledge sharing in Telegram-channel, and continuous movement to the next offline event.
Organised within a separate section at PHDays for the first time, leading security researchers and bug hunters will share the results of their work, and owners of bug bounty programs can attract bug hunters by making an announcement. During the event, our sponsors and partners will announce the highest bounties for their vulnerability disclosure programs, and the most active bug hunters will be additionally awarded by organisers.
Submit your talk, workshop or just register yourself to participate here (for Russian-based submissions).
