CVE-2023-35081

CVE-2023-35081 is a path traversal (CWE-22) vulnerability in Ivanti Endpoint Manager Mobile (EPMM), the on-premises mobile device management appliance formerly known as MobileIron Core. It is triggered when an authenticated administrator submits crafted path input, allowing the attacker to write arbitrary files onto the appliance outside intended directories. Because arbitrary files can be written to the appliance, the flaw can be leveraged to further compromise the device, and public reporting indicates it was used in real-world attacks alongside a previously disclosed EPMM authentication bypass. Organizations running EPMM 11.8.x, 11.9.x, or 11.10.x prior to the fixed builds are affected. The vulnerability is being actively exploited in the wild: it was added to CISA's Known Exploited Vulnerabilities catalog on 2023-07-31, attacks on Norwegian government entities have been reported, and no public PoC is known.

What to do: Upgrade EPMM to 11.10.0.3, 11.9.1.2, or 11.8.1.2 for the 11.10.x, 11.9.x, and 11.8.x branches respectively, and treat this as urgent given the CISA KEV listing. Until patched, restrict internet-facing access to the EPMM appliance and review the device for unexpected or newly written files and other signs of compromise. Administrators should also confirm they are not exposed via chaining with the previously disclosed EPMM authentication bypass used in the same attacks.
