Lyrics

[Verse 1]
August twenty-second, twenty-twenty-six
Three CVEs dropping, critical mix
Zimbra Collaboration Suite got cracked wide open
OS command injection, no credentials token
An unauthenticated attacker sends a crafted SMTP frame
Arbitrary commands execute — your mail server's not the same
CVE-2026-73570, Synacor's in the fire
The attack chain runs silent, sliding up the wire

[Chorus]
Seventy-three five-seventy, Zimbra's bleeding out
Seventy-two five-thirty, TrueConf's code in doubt
Seventy-two five-twenty-nine, authentication's ghost
Three critical CVEs — patch the one that hurts the most
No credentials, no permission, still they walk right through
August twenty-second, twenty-twenty-six is coming for you

[Verse 2]
Now TrueConf Server, port four-three-zero-seven TCP
A remote attacker knocks — the door swings open free
CVE-2026-72530, code injection at its worst
Crafted script breaks isolation, bypasses every burst
The attacker's sitting nowhere near the physical machine
Yet they're executing logic inside the server's seams
TrueConf running, perimeter looks clean
Deadliest intrusions are the ones you've never seen

[Chorus]
Seventy-three five-seventy, Zimbra's bleeding out
Seventy-two five-thirty, TrueConf's code in doubt
Seventy-two five-twenty-nine, authentication's ghost
Three critical CVEs — patch the one that hurts the most
No credentials, no permission, still they walk right through
August twenty-second, twenty-twenty-six is coming for you

[Bridge]
Missing authentication for a critical function
That's seventy-two five-twenty-nine at the junction
Same port, same server, different kill chain
Arbitrary script execution, zero pain
No login handshake, no identity check
Remote and unauthorized — what did you expect
Two separate wounds on the same TrueConf host
One for code injection, one for the ghost

[Verse 3]
Picture your mail server as a city sorting hub
Zimbra handling millions, stamped and catalogued with love
One poisoned envelope slips through the loading dock
Carries a command inside, picks every automated lock
Now picture TrueConf as a sealed corporate vault
TCP port open, but the guard's asleep at halt
No badge required, a script walks through the gate
Runs whatever payload — your data meets its fate

[Chorus]
Seventy-three five-seventy, Zimbra's bleeding out
Seventy-two five-thirty, TrueConf's code in doubt
Seventy-two five-twenty-nine, authentication's ghost
Three critical CVEs — patch the one that hurts the most
No credentials, no permission, still they walk right through
August twenty-second, twenty-twenty-six is coming for you

[Outro]
Check your Zimbra version, block that SMTP vector
Isolate TrueConf, port four-three-zero-seven — intercept her
Patches move at zero speed when nobody reads the feed
CVE catalog growing — plant the fix before they plant the seed
