TL;DR: 1,360 Microsoft vulnerabilities in 2024 show how much room privilege escalation still has, based on Frontegg's blog post and its cited evidence. IAM needs tighter privilege boundaries, because broad access makes containment and blast-radius reduction harder after a foothold.
Editorial analysis by NHI Mgmt Group, based on content published by Frontegg: “Privilege Escalation: Attack Techniques and 5 Defensive Measures”.
By the numbers:
- BeyondTrust reported that in 2024, 1,360 Microsoft vulnerabilities were reported, an 11% increase over the previous high in 2022.
- Elevation of Privilege vulnerabilities made up 40% of those 1,360 Microsoft vulnerabilities, or 554 issues.
Key questions
Q: Why do over-privileged accounts make privilege escalation worse?
A: Over-privileged accounts give attackers more useful pathways after a foothold.
Q: How can security teams measure whether local privilege escalation risk is actually controlled?
A: Track whether any privileged process executes from user-modifiable directories, whether ACLs on management paths are restrictive, and whether detections exist for script or DLL replacement between validation and load.
Q: What breaks when IAM access is too broad to contain privilege escalation?
A: The main failure is that a compromised account can do far more than the original task required, which turns a single foothold into a broad operational incident.
Practitioner guidance
- Reduce standing privilege Review roles, service accounts and application identities for access that is broader than the task requires, then remove persistent administrative reach wherever possible.
- Harden patch and misconfiguration management Prioritise vulnerabilities and permission errors that create elevation paths, especially on systems that already hold sensitive data or control plane access.
- Require MFA on privileged paths Apply strong authentication to privileged accounts and high-risk workflows so stolen credentials are harder to convert into elevated control.
Bottom line: Privilege escalation succeeds when the access model already gives an attacker too much room to move after the first foothold.

Over-privilege is the enabling condition, not the side effect. Privilege escalation succeeds when systems already grant more access than the task requires, so the attacker only has to bend an existing trust boundary. That makes the real issue one of governance, not just vulnerability management. Practitioners should read escalation as a symptom of excessive default reach.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Should organisations prioritise patching or access reduction to reduce privilege escalation risk?
A: Both matter, but access reduction usually gives the faster containment benefit. Patching removes known paths to escalation, while least privilege and PAM reduce the damage if one path is missed or a credential is stolen. Mature programmes do both in parallel.
