Cisco Firewalls Fall on Their Arse – Again

Oh bloody fantastic, because what the world really needed right now was another flaming Cisco screw-up. Seems those overpaid corporate clowns managed to gift-wrap yet another set of vulnerabilities for the hacker world. Two major firewall flaws — CVE-2024-20353 and CVE-2024-20359 — apparently got “actively exploited” before Cisco even finished their morning coffee. And now the bastards are being used for good old-fashioned Denial-of-Service attacks. Lovely, just lovely.

In case you missed the plot (you probably didn’t, because it’s the same every goddamn time), these flaws hit Cisco’s Adaptive Security Appliance (ASA) and Firepower Threat Defense (FTD), essentially turning expensive “enterprise-grade” firewalls into glorified sieves. Attackers realized they can smack those devices so hard they start wheezing — dropping connections, freezing up, or outright face-planting mid-session. It’s the digital equivalent of your firewall wetting itself during a mild breeze.

Cisco, in their infinite wisdom, belatedly slapped out some patches and PR fluff about “actively monitoring for exploit attempts.” Translation: “Yeah, we know it’s broken, but please don’t throw us under the compliance bus just yet.” Meanwhile, the poor sysadmins are left frantically juggling firmware updates and mitigation workarounds, because some genius vendor couldn’t sanitize their code before shipping it to half the bloody Fortune 500.

To sum up: attackers are already partying like it’s patch Tuesday every day, Cisco’s scrambling to look competent, and you — lucky bastard — get another “priority patch” weekend. Have fun rebooting your firewalls and praying they don’t brick themselves mid-update. It’s the circle of IT life — endless, cruel, and powered entirely by caffeine and despair.

Reminds me of the time a manager asked if “turning off the firewall temporarily” would fix network outages. Sure, mate, and maybe setting fire to the datacenter will improve the lighting. Some people just shouldn’t be allowed near an Ethernet cable.
