Overview

AI description

Automated description summarized from trusted sources.

CVE-2026-111357 is a privilege escalation vulnerability affecting Ivanti Connect Secure VPN appliances. The flaw stems from the system mishandling how the privileged `dsinvoked` broker trusts configuration data stored in the `DSCache`. By manipulating this trust—specifically by temporarily modifying library code in memory and altering a maintenance task in the configuration store—an attacker with local authenticated access can execute arbitrary code with root-level privileges. Discovered by cybersecurity firm Volexity, this vulnerability was actively exploited in the wild in October 2026 by a threat actor tracked as UTA0576. The attacker chained CVE-2026-111357 with an authentication bypass (CVE-2026-104935) and a predictable-filename weakness (CVE-2026-118527) to achieve unauthenticated root access on fully patched appliances, which they used to harvest Active Directory credentials and sensitive metadata. In response, Ivanti released security patches on October 29, 2026, and the Cybersecurity and Infrastructure Security Agency (CISA) added the vulnerability to its Known Exploited Vulnerabilities (KEV) catalog.

Description: Ivanti Connect Secure 22.8R2.4 mishandles the manner in which the dsinvoked broker trusts DSCache configuration data, leading to privilege escalation to root, as exploited in the wild in October 2026.
