Recommended Actions
- Prioritize immediate patching and validate internet-facing exposure. Monitor for matching exploitation attempts in your environment.
- Review sensor telemetry for request paths, attacker IPs, and payload patterns that may inform detection and exposure validation.
- Check enrichment artifacts for scanner coverage and available PoCs before rolling remediation validation.
- Use the Pro API to automate enrichment, telemetry, and workflow delivery for VM, SOC, and CTI pipelines.

CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2026-10520 Ivanti Sentry OS Command Injection Vulnerability This type of vulnerability is a frequent attack vector for malicious cyber actors and poses significant risks to the federal enterprise. Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies, updating BOD 22-01. BOD 26-04 reinforces the importance of the KEV catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA’s Known Exploited Vulnerabilities (KEV) catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied. While BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV catalog vulnerabilities. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria. Aware of an exploited vulnerability not currently listed in the KEV catalog? Submit for potential addition: KEV Nomination Form. Potential KEV additions must have a CVE ID, evidence of exploitation, and clear mitigation guidance.

OverviewOn June 9, 2026, Ivanti published a security advisory for two critical vulnerabilities affecting Ivanti Sentry (formerly known as MobileIron Sentry), which per the vendor website is an “in-line gateway that manages, encrypts, and secures traffic between the mobile device and back-end enterprise systems”. The most severe issue, CVE-2026-10520, is an OS command injection vulnerability with a CVSS score of 10.0 that allows a remote unauthenticated attacker to achieve remote code execution (RCE) with root privileges. The second vulnerability, CVE-2026-10523, is an authentication bypass vulnerability with a CVSS score of 9.9 that allows a remote unauthenticated attacker to create arbitrary administrative accounts and obtain full administrative access. Ivanti has stated that they are not aware of any customers being exploited by either of these vulnerabilities at the time of disclosure. CVECVSSv3.1CWECVE-2026-1052010.0 (Critical)OS Command Injection (CWE-78)CVE-2026-105239.9 (Critical)Authentication Bypass Using an Alternate Path or Channel (CWE-288)On June 10, 2026, watchTowr published a technical analysis of CVE-2026-10520 that includes a proof-of-concept (PoC) exploit for unauthenticated RCE. Given the trivial nature of exploitation and the availability of a public PoC, exploitation in-the-wild is likely to begin. Ivanti Sentry has featured on the CISA KEV list twice in the past (for the vulnerabilities CVE-2023-38035 and CVE-2020-15505), so we know threat actors will likely target this product. Organizations running affected versions of Ivanti Sentry should remediate these issues on an urgent basis before exploitation in-the-wild begins.Technical overview for CVE-2026-10520Based upon the technical analysis by watchTowr, CVE-2026-10520 resides in the ConfigServiceController class within the Sentry web application, which is accessible via a POST request to the unauthenticated endpoint /mics/api/v2/sentry/mics-config/handleMessage.The handleMessage endpoint...
