Top Stories
Ivanti: Max severity Sentry flaw allows code execution as root
Source: BleepingComputer | Risk: Critical | Impacted: Ivanti Sentry administrators, Enterprises using mobile device management, Perimeter security teams
Summary: Ivanti has patched two critical vulnerabilities in its Sentry secure mobile gateway solution, including a maximum-severity flaw that enables remote attackers to execute code with root privileges.
Why it matters: Remote attackers can seize control of the host operating system in Ivanti Sentry deployments, enabling lateral movement, persistence, or destruction at the infrastructure layer.
Practitioner Perspective
Organizations relying on Ivanti Sentry for secure mobile access are directly exposed to unauthenticated code execution risk if not yet patched. Attackers routinely scan for gateway appliances lagging on security fixes due to their perimeter placement and privilege. A successful exploit provides root-level access, bypassing access controls and granting operators wide latitude for further compromise or extortion. This ups the ante for prioritizing appliance patching and ensuring monitoring is not assumed to be trustworthy on compromised infrastructure. Treat this as a Tier 0 emergency requiring rapid and verifiable remediation.
Recommended Actions
- Apply the latest Ivanti Sentry patches addressing this code execution flaw without delay and verify firmware/software levels on all instances.
- Monitor Ivanti Sentry network traffic and logs for anomalous access patterns post-patch, especially spikes or suspicious authentication attempts.
ServiceNow discloses security incident exposing customer data
Source: BleepingComputer | Risk: High | Impacted: ServiceNow tenants, SaaS security managers, Enterprises processing sensitive data in ServiceNow
Summary: ServiceNow is warning about a security incident after attackers exploited an unauthenticated access flaw through a vulnerable API endpoint, allowing them to query data from customer instances.
Why it matters: Attackers able to query customer data through exposed ServiceNow API endpoints elevate risk of targeted phishing, fraud, and data loss for affected organizations.
Practitioner Perspective
Any enterprise using ServiceNow must treat exposed API endpoints as high-risk vectors for sensitive business information leakage. Given that attackers exploited an unauthenticated endpoint, there is a high probability of data access patterns that bypass conventional detection. This is a strong reminder that SaaS APIs require the same scrutiny and controls as on-prem infrastructure. It is critical to audit for unrecognized or excessive permissions and review logs for unusual query activity. Focus on post-incident forensics and notification obligations as customer trust is at stake.
Recommended Actions
- Review ServiceNow customer instance logs for unauthorized data access and anomalous API activity linked to the compromised endpoint.
- Audit ServiceNow API permissions and disable any anonymous or broad-scope API endpoints immediately.
SAP fixes critical flaws in NetWeaver and Commerce Cloud
Source: BleepingComputer | Risk: Critical | Impacted: SAP NetWeaver administrators, SAP Commerce Cloud operators, Corporate finance and accounting systems
Summary: SAP has released fixes for 15 vulnerabilities as part of its June 2026 Security Patch package, including four critical-severity flaws affecting SAP NetWeaver and SAP Commerce Cloud.
Why it matters: Critical vulnerabilities in core SAP business platforms create direct pathways to fraud, service outages, or attacker persistence within the enterprise ERP environment.
Practitioner Perspective
SAP NetWeaver and Commerce Cloud customers face a heightened threat landscape whenever critical advisories land, as organized attackers quickly reverse patches to weaponize proofs-of-concept. These platforms are often tightly integrated with sensitive workflows, amplifying the impact of compromise. Delayed patching or lack of compensating controls will leave vital ERP data exposed to theft or manipulation. Executives and SAP admins should view these updates as business risks, not just technical debt.
Recommended Actions
- Deploy SAP June 2026 security patches addressing NetWeaver and Commerce Cloud immediately, prioritizing externally-facing or internet-connected instances.
- Coordinate SAP downtime for patching with business stakeholders to minimize disruption but do not defer beyond organizational SLA.
Microsoft releases Windows 10 KB5094127 extended security update
Source: BleepingComputer | Risk: High | Impacted: Windows 10 ESU customers, Enterprise IT asset managers, Environments with Secure Boot dependencies
Summary: Microsoft has released the Windows 10 KB5094127 extended security update, which fixes the June 2026 Patch Tuesday vulnerabilities and adds new functionality to monitor the rollout of updated Secure Boot certificates that replace those expiring this month.
Why it matters: Unsupported Windows 10 deployments patched only by ESU remain at heightened risk of exploit, but the update window is narrowing as Secure Boot certificate rotation deadlines loom.
Practitioner Perspective
Organizations reliant on Extended Security Updates (ESU) for Windows 10 are balancing end-of-life risk, operational continuity, and last-chance patch coverage. The inclusion of Secure Boot certificate monitoring means defenders must track which endpoints are protected and identify any systems lagging on this essential security posture update. Delays risk exposure to mass exploitation campaigns targeting unpatched legacy systems. Do not assume ESU is a license to deprioritize upgrade planning.
Recommended Actions
- Push KB5094127 to all Windows 10 endpoints enrolled in ESU, confirming post-update Secure Boot certificate status for each device.
- Use new certificate monitoring features to inventory and remediate assets using soon-to-expire Secure Boot chains.
Windows 11 KB5094126 & KB5093998 cumulative updates released
Source: BleepingComputer | Risk: Medium | Impacted: Windows 11 fleets (23H2/24H2/25H2), Patch management teams, Remote work and BYOD environments
Summary: Microsoft has released Windows 11 KB5094126 and KB5093998 cumulative updates for versions 25H2/24H2 and 23H2 to fix security vulnerabilities, bugs, and add new features.
Why it matters: Delaying cumulative Windows 11 updates with security fixes increases the attack surface for adversaries seeking to exploit freshly disclosed flaws.
Practitioner Perspective
Any Windows 11 estate not promptly patched with KB5094126 or KB5093998 remains vulnerable to both opportunistic and targeted attacks leveraging new exploit code. Enterprises slow to incorporate these updates, especially in remote or hybrid settings, may see disproportionate exposure due to uneven patch hygiene. Coordinated rollouts across all supported versions are crucial given the diversity of threat actors zeroing in on laggards. Patch baselines must be enforced across all device classes, not just servers.
Recommended Actions
- Prioritize deployment of KB5094126 and KB5093998 cumulative updates to all eligible Windows 11 endpoints.
- Validate update installation and enforce a compliance check across group policies or MDM for unsupported versions.
