Thousands of Juniper Networks devices vulnerable to critical RCE bug
2024-01-15 19:34

More than 11,500 Juniper Networks devices are exposed to a new remote code execution vulnerability, and infosec researchers are pressing admins to urgently apply the patches.

It's somewhat of a repeat scenario for Juniper Networks, which only recently got done patching the last round of critical RCE bugs in Junos OS, which runs on SRX firewalls and EX switches.

The latest vulnerability, tracked as CVE-2024-21591, impacts the software's J-Web configuration interface and carries a 9.8 CVSS severity score, the same as August's exploit, which a threat intel platform told us the vast majority of people didn't bother patching.

The data collated by Censys confirmed the number of exposures, and scans revealed that most exposed devices also displayed their model numbers.

Juniper Networks said its incident response team hasn't spotted any signs of it being exploited in the wild yet, but that can all change in the days following vulnerability disclosures - especially when EOL equipment is involved.

In other news, Juniper Networks may soon be part of HPE in a move that will effectively double the enterprise IT giant's networking segment business.
