Cisco Aironet Series Access Points Command Injection Vulnerability
A vulnerability in the CLI of Cisco Aironet Series Access Points (APs) could allow an authenticated, local attacker to gain access to the underlying Linux operating system (OS) without the proper authentication. The attacker would need valid administrator device credentials. The vulnerability is due to improper validation of user-supplied input for certain CLI commands. An attacker could exploit this vulnerability by authenticating to an affected device and submitting crafted input for a CLI command. A successful exploit could allow the attacker to obtain access to the underlying Linux OS without proper authentication.

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.
