The US agency CISA added a second actively exploited vulnerability of Ivanti Endpoint Manager Mobile (EPMM) to its Known Exploited Vulnerabilities catalog.

This vulnerability, identified as CVE-2023-35081, joined the existing vulnerability CVE-2023-35078. CISA and the Norwegian National Cyber Security Centre (NCSC-NO) issued a joint warning in response to the active exploitation of both vulnerabilities. Ivanti released another patch for CVE-2023-35081 on July 28, 2023. The possibility of chaining the CVE-2023-35081 and CVE-2023-35078 vulnerabilities was observed.

The vulnerability affects versions 11.10, 11.9, and 11.8, and older versions are also at risk. Attackers can use this vulnerability to bypass administrator authentication and ACL restrictions, allowing them to execute system commands on the device as the user tomcat. The vulnerability was exploited in recent attacks against the ICT system used by twelve Norwegian government ministries.

It is noteworthy that mobile device management systems (MDM) are attractive targets for attackers, as compromising them provides elevated access to thousands of mobile devices. CISA and NCSC-NO warn of the potential for widespread exploitation of Ivanti vulnerabilities in government and private sector networks.

As part of their emerging vulnerabilities service, Tarlogic proactively monitors their clients’ perimeter to inform, detect, and urgently report the presence of this vulnerability, as well as other critical threats that could have a serious impact on asset security.
