Ep. 11 – Account Takeover, Token Misuse, and Deserialization RCE: When Trust Goes Wrong

Hacked & Secured: Pentest Exploits & Mitigations

One flawed password reset. One shared session token. One dangerous object.

In Episode 11 of Hacked & Secured: Pentest Exploits & Mitigations, we break down three real-world vulnerabilities where trust between systems and users broke down—with serious consequences.

• Account Takeover via Forgot Password – A predictable ID and exposed tokens let attackers reset passwords without access to email.
• Session Hijack in OTP Login – A logic flaw in how login tokens were handled allowed full account access with just a user ID.
• Remote Code Execution via Java Deserialization – A community-contributed finding where an exposed service deserialized untrusted input, leading to code execution.

These aren’t complex chains. They’re common mistakes with big impact—and important lessons for developers, security teams, and testers.
