HPE Finally Patches a Nasty ArubaOS-CX RCE Before More People Screw Themselves

Right, so HPE has shoved out patches for a critical remote code execution flaw in ArubaOS-CX, which is the sort of sentence that makes sysadmins sigh, reach for coffee, and wonder which idiot thought exposing fragile management services to the network was a good idea.

The bug, tracked as CVE-2025-37103, has a CVSS score of 9.8, which in security terms translates to: “drop what you’re doing and fix this shit now.” It affects the Command Line Interface service on Aruba switches running vulnerable versions of ArubaOS-CX. If exploited, an unauthenticated attacker could pull off remote code execution. Yes, unauthenticated. As in, they don’t need to log in first. Brilliant.

According to HPE, the flaw impacts ArubaOS-CX 10.13.x.x before 10.13.1010, 10.14.x.x before 10.14.1000, 10.15.x.x before 10.15.1000, and 10.16.x.x before 10.16.1000. So if you’re sitting on those older builds because “we’ll patch next maintenance window,” congratulations, you’ve been babysitting a potential dumpster fire.

The good news, if you can call it that, is HPE says there are no reports of active exploitation so far. Which usually means either nobody’s found a reliable way to abuse it yet, or they have and just haven’t bothered telling you while they quietly rummage through networks like thieves in a data center at 3 a.m.

There’s no workaround either, because of course there bloody isn’t. The fix is to install the patched versions. That’s it. Patch the damn switches. If you can’t patch immediately, HPE suggests disabling the CLI service on SSL/TLS-enabled VRFs as a mitigation, which is the vendor equivalent of saying, “Try not to get stabbed while we sort out the knife problem.”

The broader lesson, for the ten thousandth miserable time, is that network gear is not magical fairy hardware immune to security screwups. It runs software, software has bugs, and bugs turn into RCEs when people cut corners, skip updates, or leave management interfaces hanging out on the network like bait. Then everyone acts shocked when the whole thing goes sideways. Fucking predictable.

So, in summary: critical bug, no auth required, remote code execution possible, patch immediately. If you’re running affected ArubaOS-CX versions and haven’t updated, stop reading breathless vendor PDFs, stop scheduling meetings about scheduling the patch, and just fix the bloody thing.

Anecdote time: years ago, I watched a network admin insist a switch firmware update could wait because “it’s only infrastructure.” Two days later, the same poor bastard was crawling around a freezing comms room at midnight because a “minor” issue became a full-blown outage. Moral of the story: infrastructure bugs don’t stay minor just because you ignore the bastard hard enough.
