Critical Infrastructure Brief: FortiOS LDAP auth bypass; Microsoft patches six zero‑days; Adobe updates available

TLDR

Act now: 1) Prioritize FortiOS fixes/mitigations for an LDAP authentication bypass; restrict admin exposure and monitor login anomalies [6]. 2) Apply Microsoft February Patch Tuesday updates addressing six zero‑days [1]. 3) Update Adobe apps (no exploitation,但

A FortiOS issue enabling LDAP login bypass poses immediate perimeter risk and warrants rapid patching and access hardening [6]. Microsoft’s February Patch Tuesday addresses six zero‑days requiring expedited deployment [1]. Adobe released security patches for multiple apps; no active attacks reported yet, but updates is

What’s new and high‑risk

FortiOS LDAP authentication bypass: Reported vulnerability allows attackers to bypass LDAP login on FortiOS [6]. Likely high impact for perimeter devices common in enterprise/OT environments. Details in the source are limited; treat as priority.
Immediate actions: Apply Fortinet fixes if available; if not, temporarily limit or disable LDAP-based admin auth, restrict management interfaces to trusted networks, and monitor for anomalous authentication activity [6].

Microsoft Patch Tuesday (February): Microsoft released fixes for six zero‑days [1]. No additional technical details in the provided source, but urgency is high.
Immediate actions: Expedite patching of supported Windows/Server/Edge components per internal criticality, and track known‑exploited updates in this cycle [1].

Adobe updates: Security patches released for After Effects and other Adobe apps; multiple vulnerabilities addressed. No reports of in‑the‑wild attacks so far [3][5].
Immediate actions: Update Creative Cloud/enterprise‑deployed Adobe apps, especially on shared or externally exposed workstations [3][5].

Ransomware and service disruptions

No confirmed ransomware events or public‑infrastructure outages are reported in the provided sources. Continue monitoring for corroborated incident reports.

Detection and mitigation priorities (near term)

FortiOS: Alert on unexpected successful admin logins via LDAP, unusual source geolocations, new/unscheduled management sessions, and rapid sequences of failed→successful LDAP attempts [6]. Restrict management plane exposure and ensure backups/config baselines are current.
Enterprise hygiene: Accelerate deployment of Microsoft February patches [1] and Adobe updates [3][5]. Validate egress/ingress controls around security appliances and enforce MFA for administrative access where supported.
