U.S. CISA warns of actively exploited Ivanti EPMM flaw CVE-2023-35082

U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Ivanti EPMM flaw CVE-2023-35082 to its Known Exploited Vulnerabilities catalog.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the Ivanti EPMM flaw CVE-2023-35082 (CVSS score: 9.8) vulnerability to its Known Exploited Vulnerabilities (KEV) catalog.

At the end of July, Ivanti disclosed a security vulnerability impacting Endpoint Manager Mobile (EPMM), tracked as CVE-2023-35078 (CVSS score: 7.8), that was exploited in the wild as part of an exploit chain by threat actors.

In early August, Rapid7 researchers discovered a bypass for the CVE-2023-35078 vulnerability in Ivanti Endpoint Manager Mobile (EPMM).

The new vulnerability, tracked as CVE-2023-35082 (CVSS score: 10.0), can be exploited by unauthenticated attackers to access the API in older unsupported versions of MobileIron Core (11.2 and below). Ivanti addressed the vulnerability with the release of the MobileIron Core 11.3 version.

“If exploited, this vulnerability enables an unauthorized, remote (internet-facing) actor to potentially access users’ personally identifiable information and make limited changes to the server,” Ivanti reported in August 2023.

According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog.

Experts recommend also private organizations review the Catalog and address the vulnerabilities in their infrastructure.

CISA orders federal agencies to fix this vulnerability by February 8, 2024.
