Cisco Integrated Management Controller Command Injection Vulnerability
A vulnerability in the Redfish protocol of Cisco Integrated Management Controller (IMC) could allow an authenticated, remote attacker to inject and execute arbitrary commands with root privileges on an affected device. The vulnerability is due to insufficient validation of user-supplied input by the affected software. An attacker could exploit this vulnerability by sending crafted authenticated commands to the web-based management interface of the affected software. A successful exploit could allow the attacker to inject and execute arbitrary commands on an affected device with root privileges.

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.
