Cisco’s Double Whammy: Two Zero-Days Wreaking Havoc in Tech Town!

Cisco’s Zero-Day Exploit is like a cyber villain’s all-access pass, and boy, are they having fun! With one exploit following another, it’s a real-life ‘whack-a-mole’ for network admins. But fear not, Cisco’s riding to the rescue with a weekend fix. Until then, keep your eyes peeled and your tech ducks in a row!

Hot Take:

Just when you thought you had your tech ducks in a row, Cisco pops up with another “oh by the way” zero-day vulnerability. Now, it’s an IOS XE privilege escalation zero-day, and the cyber bandits are already having a field day with it. It’s like an all-access pass to your Cisco IOS XE devices, and they’re loving it! And let’s not forget about the authentication bypass zero-day from earlier this week. It’s like the villain twins of the cyber world. Most importantly, keep an eye on your calendar because Cisco’s got a fix coming up this weekend. Well, better late than hacked!

Key Points:

  • Cisco has announced a high-severity zero-day (CVE-2023-20273) vulnerability, actively exploited to plant malicious implants on IOS XE devices.
  • This comes on the heels of the CVE-2023-20198 zero-day that was revealed earlier this week.
  • An estimated 40,000 Cisco devices running the vulnerable IOS XE software have already been compromised.
  • Although security updates are not yet available, administrators can block incoming attacks by disabling the vulnerable HTTP server feature.
  • A fix for both vulnerabilities is anticipated to be available to customers on October 22.

When it rains, it pours

Just when you'd caught your breath from the CVE-2023-20198 authentication bypass zero-day, Cisco unveils a new villain in town. The CVE-2023-20273 privilege escalation zero-day is being used to gain root access to your beloved Cisco IOS XE devices and plant malicious implants. Hackers are practically playing puppet master with your devices, making them dance to their tunes.

Counting the victims

The number of compromised devices is rising faster than you can say 'zero-day vulnerability'. With over 40,000 Cisco devices already compromised, it's a cyber crime wave that shows no signs of stopping. And the worst part? There could be more out there, with an estimated 146K vulnerable systems hanging like ripe fruit for the hackers.

The cavalry is coming

But don't lose heart yet, dear admins! Cisco is riding to the rescue with fixes for both these vulnerabilities. The patches are expected to be available on October 22. Until then, you can block incoming attacks by disabling the vulnerable HTTP server feature.

Keep your eyes peeled

While waiting for the cavalry, keep an eye out for suspicious or newly created user accounts. They could be signs of malicious activities associated with these ongoing attacks. With the right protective measures, you can keep your network safe from these cyber villains.
