Ivanti Finally Patches One Damn Hole, But Leaves Another Bloody Window Open

Right, here’s the sorry mess: Ivanti has patched a zero-day flaw in its Connect Secure and Policy Secure products, which is nice and all, except the attack chain used by the bad bastards apparently includes a third vulnerability that still isn’t fixed. So yes, they’ve slapped a plaster on one arterial spray while the server room is still on fire. Brilliant.

The article explains that Ivanti addressed CVE-2025-22457, a stack-based buffer overflow bug. According to researchers, this flaw could be exploited in combination with two other bugs to compromise systems. Ivanti’s patch closes that particular hole, but the larger problem is that attackers were reportedly chaining multiple vulnerabilities together, and one of the components in that chain remains open. In other words: the bastards got in through a sequence of doors, and Ivanti has only bothered to lock some of them.

Security researchers observed active exploitation in the wild, because of course they did. These things are never theoretical for long. Once criminals find a working chain, they don’t sit around admiring the elegance of the exploit—they hammer every exposed box they can find. So if you’re running Ivanti kit and thinking, “Well, they patched one CVE, we’re probably fine,” then congratulations, you’re exactly the sort of optimistic fool attackers love.

The important bit is that patching the disclosed zero-day does not magically eliminate the whole attack path. That’s the bit admins tend to miss while management is busy asking whether the latest patch means everything is “resolved.” No, Karen, it means one specific flaming pile of shit is slightly less flammable. The remaining flaw still gives attackers room to work with, which means defenders need to pay attention to mitigations, monitoring, indicators of compromise, and vendor guidance instead of treating this like a one-and-done update cycle.

The article also highlights the ugly reality of modern appliance security: edge devices get popped, vendors rush out fixes, and everyone pretends the crisis is over while incident responders are still knee-deep in logs, malware, and bad decisions. If the attack chain isn’t fully broken, then the threat isn’t gone—it’s just wearing a slightly different hat.

So the summary is simple: Ivanti fixed one exploited vulnerability, but the full attack chain still includes an unpatched flaw. That means organizations using the affected products shouldn’t sit on their arses congratulating themselves after one update. Patch what you can, apply mitigations, hunt for signs of compromise, and assume hostile little shits are already probing your perimeter.

This reminds me of a place where they proudly announced they’d “secured” the server room after installing a shiny new lock—while leaving the loading bay door open because the air conditioning was better that way. They were absolutely stunned when someone walked out with three laptops and a backup tape. That, in essence, is what this Ivanti story feels like.
