Attackers are exploiting a critical authentication bypass vulnerability (CVE-2025-2825) in CrushFTP software. While CrushFTP hurried to patch the flaw, over 1,500 unpatched instances remain vulnerable online. It’s a bad day to be an exposed HTTP(S) port! Time to patch those servers or face the wrath of cyber mischief!

Hot Take:

CrushFTP is proving to be the software equivalent of that one sock that keeps getting lost in the laundry—no matter how many times you fix it, it keeps disappearing or, in this case, opening up security holes! Meanwhile, hackers are having a field day with the proof-of-concept code like it’s the latest viral dance trend. If only we could patch our real-life issues as quickly as we should patch our software vulnerabilities.

  • Over 1,500 vulnerable instances of CrushFTP are currently exposed online.
  • Exploit attempts are based on publicly available proof-of-concept code.
  • Admins can temporarily use a DMZ as a workaround if immediate patching isn’t possible.
