Two Critical vulnerabilities in Ivanti’s popular mobile device management solution have been exploited in the wild in limited attacks

Background

On January 29, Ivanti released a security advisory to address two critical severity remote code execution (RCE) vulnerabilities in its Endpoint Manager Mobile (EPMM), formerly known as MobileIron Core, a mobile management software used for mobile device management (MDM), mobile application management (MAM) and mobile content management (MCM).

Analysis

CVE-2026-1281 and CVE-2026-1340 are both code injection vulnerabilities in Ivanti’s EPMM. An unauthenticated attacker could exploit these vulnerabilities to gain remote code execution.

Limited exploitation observed

According to Ivanti, both CVE-2026-1281 and CVE-2026-1340 were exploited as zero-days affecting “a very limited number of customers.” Because its investigation is ongoing, Ivanti has not yet provided any indicators of compromise in relation to these attacks.

Historical exploitation of Ivanti Endpoint Mobile Manager

Ivanti products in general are a popular target for a variety of attackers. EPMM in particular has been targeted in the past, and the Tenable Research Special Operations (RSO) team has authored several blogs about these vulnerabilities. The following table outlines some of the notable EPMM vulnerabilities over the last six years:

Proof of concept

At the time this blog was published on January 30, a public proof-of-concept (PoC) exploit was publicly available. We expect attackers will begin to leverage this PoC to conduct mass scanning and exploitation attempts against vulnerable devices.

Solution

Ivanti has released temporary updates that can be applied to address these vulnerabilities. According to the advisory, the RPMs supplied should be applied based on the installed version of EPMM. The RPMs will not survive a version upgrade, so if the version is updated, the RPM would need to be applied once again. However, the advisory further notes that an upcoming release, version 12.8.0.0, is expected to be released in Q1 2026., T and this version will include the permanent fix for these CVEs. Once version 12.8.0.0 is released and applied, the RPM scripts will no longer need to be applied.

For more information on the patches, we strongly recommend reviewing the guidance in the security advisory from Ivanti.
