BMC IPMI Privilege Escalation via Malformed RAKP Messages

A logic flaw in the BMC IPMI implementation may allow an attacker to send specially crafted RAKP+ messages and escalate an account to administrator privileges.

Casky was already ahead

This CVE exploits attack patterns that Casky's 224matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-65220 represents a critical authentication bypass in BMC IPMI implementations where a logic flaw in RAKP+ (Remote Authentication Kernel Protocol Plus) message handling allows attackers to escalate unprivileged accounts to administrator status. This vulnerability is particularly dangerous because IPMI is the de facto standard for out-of-band management across enterprise data centers, hypervisors, and critical infrastructure. Any organization running BMC-based baseboard management controllers is potentially affected, making this a widespread risk affecting system administrators, cloud providers, and managed service providers who rely on IPMI for remote server access and management.

Casky's 224 mapped skills enable detection of the privilege escalation patterns underlying TA0004 (Privilege Escalation) through Claude's extended reasoning capabilities. When analyzing network traffic and authentication logs, Casky would identify anomalies such as: sudden privilege level changes from standard user to admin without corresponding credential submissions, malformed or oversized RAKP+ packets that deviate from RFC specifications, and authentication state transitions that violate normal IPMI session establishment workflows. Practitioners using Casky would see alerts flagging CWE-269 (Improper Access Control) violations, including detection of crafted RAKP messages attempting to bypass cryptographic validation steps, failed authentication attempts followed immediately by successful admin actions, and session hijacking indicators where low-privilege sessions inherit high-privilege capabilities. The platform's skill mapping to privilege escalation techniques would help security teams correlate these IPMI-specific attack signatures with broader lateral movement campaigns targeting infrastructure access.
