Ivanti Endpoint Manager Mobile (EPMM) vulnerability

Ivanti EPMM contains a path traversal vulnerability (CWE-22) allowing authenticated administrators to write malicious files to the server, potentially chained with authentication bypass techniques.

Verdict

Today item — known-exploited.

An authenticated administrator can exploit path traversal to write arbitrary files to the EPMM server. When combined with CVE-2023-35078, this may enable unauthenticated attackers to bypass access controls and establish persistence or execute code.

Who’s exploiting it?

— attribution turns risk into urgency
Attribution not established

No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.

Why it matters

— the attack path, told twice: adversary, then board
1

Front door — unauthenticated access narrative 1

Attacker
I gain valid administrator credentials through phishing, credential stuffing, or insider access.
Business
Administrative account compromise exposes the organization to insider threats and lateral movement within the management infrastructure.
2

Keys to the kingdom — privilege/identity takeover narrative 2

Attacker
I use the path traversal flaw to write malicious files outside the intended directory on the EPMM server.
Business
Arbitrary file writes enable attackers to modify system configurations, inject malware, or alter audit logs, undermining system integrity.
3

Lateral reach — past segmentation narrative 3

Attacker
I chain this vulnerability with CVE-2023-35078 to bypass authentication and access controls without valid credentials.
Business
Unauthenticated remote exploitation converts a privileged attack into a public-facing threat, dramatically expanding attack surface and incident scope.

What to do

— defensible action
  • Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
