Cisco Network Services Orchestrator Network Plug and Play Information Disclosure Vulnerability
A vulnerability in the Cisco Network Plug and Play server component of Cisco Network Services Orchestrator (NSO) could allow an unauthenticated, remote attacker to gain unauthorized access to configuration data that is stored on an affected NSO system. The vulnerability exists because the Network Plug and Play component performs incomplete validation when configured to use secure unique device identifiers (SUDI) for authentication. An attacker who controls a Cisco device that supports SUDI authentication and has connectivity to an affected NSO system could exploit this vulnerability. The attacker would need to leverage information about the devices that are being registered on the NSO server to send crafted Cisco Network Plug and Play authentication packets to an affected system. A successful exploit could allow the attacker to gain unauthorized access to configuration data for devices that will be managed by the NSO system.

Remediation
Which version to upgrade to
Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.
No fix version is recorded for this entry. Check the references for vendor advisories.
Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
