Security Advisory: Windows ActiveX CVE-2008-0015 (Known Exploited Vulnerability)

DataComm is monitoring CVE-2008-0015, a legacy remote code execution vulnerability in Microsoft’s Windows Video ActiveX control (msvidctl.dll) that can be triggered when a user visits a specially crafted web page. While the CVE is older, it remains relevant today because it is listed in CISA’s Known Exploited Vulnerabilities (KEV) Catalog, indicating evidence of real-world exploitation. Organizations should identify any remaining exposure (especially legacy Internet Explorer/ActiveX dependencies), apply available vendor mitigations/updates, and prioritize upgrade or decommissioning of unsupported systems to reduce risk.

Security Advisory: Apple CVE-2026-20700 (Active Exploitation)

DataComm is monitoring CVE-2026-20700, an Apple zero-day vulnerability impacting the Dynamic Link Editor component. Apple reports the issue may have been exploited in an extremely sophisticated attack against targeted individuals and that successful exploitation could enable arbitrary code execution under certain conditions. We recommend organizations and users apply Apple’s latest security updates immediately—including iOS/iPadOS 26.3 and corresponding updates for macOS Tahoe 26.3, watchOS 26.3, tvOS 26.3, and visionOS 26.3—to reduce exposure.

Security Advisory: Notepad++ CVE-2025-15556 (Actively Exploited)

DataComm is monitoring CVE-2025-15556, a vulnerability affecting Notepad++ (versions prior to 8.8.9) when using the WinGUp auto-updater. The issue stems from insufficient update integrity verification, meaning an attacker who can intercept or redirect update traffic could potentially trick systems into installing a malicious update, leading to arbitrary code execution with the user’s privileges. We recommend organizations upgrade Notepad++ to v8.8.9 or later and validate that endpoints are no longer running vulnerable versions, especially in managed environments where Notepad++ is widely deployed.

DataComm is monitoring CVE-2024-43468, a critical (CVSS 9.8) vulnerability in Microsoft Configuration Manager (SCCM) involving SQL injection that can lead to unauthenticated remote code execution. This CVE has been added to CISA’s Known Exploited Vulnerabilities (KEV) Catalog (Date Added: Feb 12, 2026; federal remediation due Mar 5, 2026), indicating active exploitation risk and elevating patch urgency. We recommend organizations apply Microsoft’s updates immediately, validate Configuration Manager site server exposure, and confirm remediation across managed environments.
