Ivanti is urging customers to quickly patch a critical vulnerability in its Endpoint Manager (EPM) product that could let remote attackers execute arbitrary JavaScript in administrator sessions through low-complexity cross-site scripting (XSS) attacks.The issue, tracked as CVE-2025-10573, affects the EPM web service and can be abused without authentication, but does require some user interaction to trigger. The flaw stems from how Ivanti EPM handles managed endpoints presented to the primary web service. According to Rapid7 researcher Ryan Emmons, an attacker with unauthenticated access to the EPM web interface can register bogus managed endpoints and inject malicious JavaScript into the administrator dashboard. Once an EPM administrator views a poisoned dashboard widget as part of routine use, the injected code executes in the browser, allowing the attacker to hijack the admin session and act with their privileges. Patch availability and exposure Ivanti has released EPM 2024 SU4 SR1 to remediate CVE-2025-10573 and recommends customers install this update as soon as possible. The company stressed that EPM is designed to operate behind perimeter defenses and not be directly exposed to the public internet, which should lower practical risk where deployments follow guidance.However, data from the Shadowserver Foundation shows hundreds of Ivanti EPM instances reachable online, with the highest counts in the United States, Germany, and Japan, significantly increasing potential attack surface for those organizations. Alongside the critical bug, Ivanti shipped fixes for three other high‑severity vulnerabilities affecting EPM, including CVE-2025-13659 and CVE-2025-13662. These two issues could also enable unauthenticated remote attackers to execute arbitrary code on vulnerable systems under certain conditions. Successful exploitation of the newly disclosed high‑severity flaws requires user interaction and either connecting to an untrusted core server or importing untrusted configuration files, which slightly raises the bar for real-world attacks. Threat landscape and prior exploitation Ivanti stated there is currently no evidence that any of the newly patched flaws have been exploited in the wild and credited its responsible disclosure program for bringing them to light. Nonetheless, EPM vulnerabilities have been frequent targets, and U.S. Cybersecurity and Infrastructure Security Agency (CISA) has repeatedly added Ivanti EPM bugs to its catalog of exploited vulnerabilities. In 2024, CISA ordered federal agencies to urgently patch multiple Ivanti EPM issues, including three critical flaws flagged in March and another actively exploited vulnerability mandated for remediation in October.

Cisco released urgent patches for a critical Integrated Management Controller (IMC) authentication bypass (CVE-2026-20093) and a Smart Software Manager On-Prem (SSM On-Prem) remote command execution flaw (CVE-2026-20160). Customers should update to the fixed versions immediately because both flaws carry CVSS scores of 9.8 and no workaround is available. #CVE-2026-20093 #CVE-2026-20160...
