Firewall Fiasco: GFI KerioControl Vulnerability Sparks Remote Code Execution Chaos!
Threat actors are turning GFI KerioControl firewalls into Swiss cheese by exploiting CVE-2024-52875, a bug so glaring you’d think it was auditioning for a horror film. It allows one-click remote code execution, which is just fancy talk for, “Hey admin, click here for a really bad time!” Update your systems, folks!

Hot Take:
Well, well, well, another day, another vulnerability. Looks like cyber baddies have found a new toy to play with in the form of a GFI KerioControl firewall exploit. Who knew splitting HTTP responses could be so much fun? It’s like a hacker’s version of a piñata, but instead of candy, you get remote code execution! So, admins, keep your clicking fingers in check, or you might end up opening a Pandora’s box of malicious .img files. Remember, just say no to suspicious URLs, unless you fancy playing tech support to a bunch of root shells!
Key Points:
- GFI KerioControl firewall has a vulnerability leading to one-click remote code execution (RCE).
- Exploitation relies on an HTTP response splitting flaw, allowing reflected cross-site scripting (XSS).
- The issue has been lurking for around seven years and impacts versions 9.2.5 through 9.4.5.
- GreyNoise observed multiple exploitation attempts; attackers can trick admins with malicious URLs.
- Updating to GFI KerioControl version 9.4.5 Patch 1 is advised to fix the vulnerability.
