Detection & IOCsextracted from sources · hover to see the quote
- →Monitor for authentication bypass attempts against the MICS Admin Portal (MICSLogService) on port 8443; the vulnerability stems from an insufficiently restrictive Apache HTTPD configuration allowing unauthenticated access to administrative API endpoints. ↗
- →Successful exploitation can lead to unauthenticated remote code execution as root and configuration changes to the server and underlying OS; monitor for unexpected root-level process execution originating from the Sentry web service. ↗
- →GreyNoise continues to observe active scan/exploit attempts targeting CVE-2023-38035; correlate inbound traffic to port 8443 on Ivanti Sentry appliances against GreyNoise tag 'IVANTI (MOBILEIRON) SENTRY AUTH BYPASS ATTEMPT'. ↗
- →A public Metasploit module exists for CVE-2023-38035 (ivanti_sentry_misc_log_service.rb) targeting the MICSLogService endpoint; detection rules should account for exploitation tooling using this module. ↗
- →A public PoC exploit was published by the Horizon3 Attack Team on August 23, 2023; treat any Ivanti Sentry 9.18.0 and below exposed on port 8443 as likely targeted. ↗
- ·The vulnerability is rooted in an insufficiently restrictive Apache HTTPD configuration on the MICS Admin Portal; organizations that do not expose port 8443 to the internet have a lower (but not zero) risk of exploitation. ↗
- ·At time of initial disclosure no patch was available; Ivanti provided RPM scripts as a workaround. Ensure the vendor-supplied RPM scripts have been applied to all affected Ivanti MobileIron Sentry 9.18.0 and below instances. ↗

CVE-2026-10520 [CRITICAL] CVE-2026-10520, CVE-2026-10523 - Multiple critical vulnerabilities affecting Ivanti Sentry
## Overview
On 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

CVE-2023-35082 [CRITICAL] CISA: Critical Ivanti auth bypass bug now actively exploited
## CISA: Critical Ivanti auth bypass bug now actively exploited
## Sergiu Gatlan
CISA warns that a critical authentication bypass vulnerability in Ivanti's Endpoint Manager Mobile (EPMM) and MobileIron Core device management software (patched in August 2023 ) is now under active exploitation.
Tracked as CVE-2023-35082 , the flaw is a remote unauthenticated API access vulnerability affecting all versions of EPMM 11.10, 11.9, and 11.8 and MobileIron Core 11.7 and below,.
Successful exploitation provides attackers access to personally identifiable information (PII) of mobile device users and can let them backdoor compromised servers when chaining the bug with other flaws.

## Ivanti Connect Secure zero-days now under mass exploitation
## Sergiu Gatlan
Two zero-day vulnerabilities affecting Ivanti's Connect Secure VPN and Policy Secure network access control (NAC) appliances are now under mass exploitation.
As discovered by threat intelligence company Volexity, which also first spotted the zero-days being used in attacks since December , multiple threat groups chain the CVE-2023-46805 authentication bypass and the CVE-2024-21887 command injection vulnerabilities in widespread attacks starting January 11.
"Victims are globally distributed and vary greatly in size, from small businesses to some of the largest organizations in the world, including multiple Fortune 500 companies across multiple industry verticals," Volexity warned today.

CVE-2023-46805 [HIGH] Ivanti warns of Connect Secure zero-days exploited in attacks
## Ivanti warns of Connect Secure zero-days exploited in attacks
## Sergiu Gatlan
Ivanti has disclosed two Connect Secure (ICS) and Policy Secure (IPS) zero-days exploited by suspected Chinese hackers in the wild that can let remote attackers execute arbitrary commands on targeted gateways.
The first security flaw (CVE-2023-46805) is an authentication bypass in the appliances' web component, enabling attackers to access restricted resources by circumventing control checks, while the second (tracked as CVE-2024-21887) is a command injection vulnerability that lets authenticated admins execute arbitrary commands on vulnerable appliances by sending specially crafted requests.
When successfully chaining the two zero days, threat actors can run arbitrary commands on all supported versions o

CVE-2023-39336 [CRITICAL] Ivanti warns critical EPM bug lets hackers hijack enrolled devices
## Ivanti warns critical EPM bug lets hackers hijack enrolled devices
## Sergiu Gatlan
Ivanti fixed a critical remote code execution (RCE) vulnerability in its Endpoint Management software (EPM) that can let unauthenticated attackers hijack enrolled devices or the core server.
Ivanti EPM helps manage client devices running a wide range of platforms, from Windows and macOS to Chrome OS and IoT operating systems.
The security flaw (tracked as CVE-2023-39336 ) impacts all supported Ivanti EPM versions, and it has been resolved in version 2022 Service Update 5.
Attackers with access to a target's internal network can exploit the vulnerability in low-complexity attacks that don't require privileges or user interaction.
"If exploited, an attacker with access to the internal network can lev
