JetBrains TeamCity Authentication Bypass: A Hacker’s Delight or SysAdmin’s Nightmare?
JetBrains TeamCity pre-2023.11.4 has a critical authentication bypass vulnerability (CVE-2024-27198). This flaw could allow attackers to perform administrative actions, possibly leading to a “Oops, I did it again” moment for your server. So, update before someone else “administers” your TeamCity!

Our favorite software dev tool just got a major wake-up call with a vulnerability that’s more gaping than your Monday morning coffee mug. With the CVSS score at a solid 9.8, this is one exploit that doesn’t need caffeine to wake up and smell the security breach. Grab your patches faster than you grab your morning coffee, because this flaw is serving up admin access on a silver platter! Oh, and the method? A path traversal-like technique – it’s like your code decided to take a scenic route right through your security protocols. Yikes!
Key Points:
