The CVE Panic-to-Apathy Pipeline for Irrelevant Services
Description
This is a two-panel meme featuring the character Squidward Tentacles from the cartoon Spongebob Squarepants, often used to show excitement followed by disappointment or retreat. In the top panel, Squidward is happily setting up a blue lounge chair, ready to relax. Next to this image is the text, '9.9 SEVERITY UNIX CVE, CAN BE EXECUTED REMOTELY.' This describes a critical security vulnerability (CVE) that would normally cause immediate panic for any operations or security team. In the bottom panel, Squidward, now looking annoyed and resigned, is folding up his chair and going back inside his house. The text next to this panel reveals the reason for his change of heart: 'IT'S CUPS'. The joke is aimed at experienced system administrators, SREs, and security engineers. CUPS stands for the Common Unix Printing System. While a remote execution vulnerability in a core service is extremely dangerous in theory, CUPS is a service for printing, which is almost never used or exposed to the internet on modern cloud servers. Therefore, the critical alert is practically irrelevant, and the engineer can dismiss the panic and go back to relaxing

A 9.9 CVE in CUPS is the Schrödinger's cat of security alerts: it's simultaneously a critical vulnerability and completely irrelevant until you check if the service is actually enabled anywhere other than a dusty server from 2003
Nothing empties a war room faster than realizing the ‘critical RCE’ listens on port 631 - and every firewall rule since 2007 already /dev/nulls it
After 20 years of arguing that printers are the spawn of Satan, we finally have CVE-level proof - though we didn't expect the attack vector to be 'existing on the network' rather than 'paper jam on line 1'
When your vulnerability disclosure gets a 9.9 CVSS score and promises remote code execution, but the attack chain requires the target to have CUPS installed, exposed to the network, and actively processing print jobs - suddenly every CISO realizes their threat model didn't account for the one server still running lpd from 1997. It's the security equivalent of discovering your house is vulnerable to catapult attacks: technically true, impressively severe on paper, but requiring an adversary with both the capability and inexplicable motivation to deploy siege equipment in your suburban neighborhood
Risk triage in one slide: CVSS 9.9 RCE alert - then you remember our hardened headless images don’t ship cupsd and 631 is closed, so the SLA becomes “patch when someone needs to print from prod.”
CVSS 9.9? Wake me when it listens on 443; if it’s CUPS on 631, that’s an uninstall-cups.yml change, not a Sev-1 bridge
CUPS: Turning 'print queue' into 'root shell queue' faster than you can say buffer overflow
At least it wasn't MUGS Comment deleted

I remember my good ol' days back in 2009 when I had a Canon printer, and an ol' notebook with Debian installed (without any desktop environment). I dunno why, I was just like "I need to learn Linux, terminal, etc". And that, here I am, in Siberian village, on a cold winter day, setting up Cups for my printer, so it will be available through a network. It was fun. To me it was surprise, that cups was made by apple inc. I dunno why I'm telling this, may be just to share that feeling of freedom and learning something new on my own will. I was 16. Yeah, sometimes it's just the best freedom you had, when you have no duties, and you on your own. Comment deleted
