Privilege escalation in IAM systems: where current controls break

TL;DR: Privilege escalation lets attackers move from ordinary access to administrative control by exploiting misconfigurations, software flaws, or stolen credentials, and BeyondTrust reported 1,360 Microsoft vulnerabilities in 2024, with 40% classified as elevation-of-privilege issues. The control gap is not theoretical: many IAM programmes still assume access boundaries hold after compromise, when they often do not.

NHIMG editorial — based on content published by Frontegg: the complete guide to privilege escalation

By the numbers:

• BeyondTrust reported that in 2024, a record-breaking 1,360 Microsoft vulnerabilities were reported, which is an 11% increase over the previous high in 2022.

Questions worth separating out

Q: How should security teams reduce privilege escalation risk in enterprise environments?

A: Start by shrinking the amount of access any account can misuse.

Q: Why do over-privileged accounts make privilege escalation worse?

A: Over-privileged accounts give attackers more useful pathways after a foothold.

Q: What do teams get wrong about privilege escalation detection?

A: They often monitor for obvious admin actions but miss the earlier signals, such as abnormal permission changes, unusual token use, or access to peer-level data.

Practitioner guidance

• Tighten privilege scope at the entitlement layer Review whether users, service accounts, and application identities can reach more systems or actions than their current task requires.
• Prioritise patching for elevation paths Map vulnerabilities that create local or application-level privilege escalation, then rank them ahead of lower-impact issues.
• Add session monitoring to privileged access Watch for unexpected elevation requests, token misuse, new admin activity, and changes made immediately after privilege increases.

Frontegg's full article covers the operational detail this post intentionally leaves for the source:

• Step-by-step examples of vertical and horizontal privilege escalation across Windows, Linux, and Android environments
• Specific technical techniques such as DLL hijacking, LSASS credential extraction, SUID abuse, and token impersonation
• A longer list of prevention measures, including containerisation, kernel-level constraints, and secrets management options
• The article's glossary of operating-system terms and references for teams that want to dig into the platform details
