September Windows Server updates break RDS connectivity

🖥️ Administrators report that September 2026 cumulative updates are causing Remote Desktop Services (RDS) failures on Windows Server 2019, 2022, and 2025, preventing users from connecting and sometimes requiring hard resets. Affected servers often run normally for hours after patching before RDS connections start failing; existing sessions may not disconnect and new connections hang. Rolling back the updates restores functionality, but also removes security fixes. Microsoft is aware and investigating.

CISA warns of active exploits in three products

🚨 The U.S. Cybersecurity and Infrastructure Security Agency has issued an urgent directive requiring federal agencies to mitigate actively exploited vulnerabilities in IBM Langflow, N-central, and Apache Tomcat within three days. The most severe issue, tracked as CVE-2026-9198, impacts Langflow and permits unauthenticated remote code execution via chained API endpoints. Vendors have released patches and a hotfix, but incomplete fixes and public proof-of-concept exploits have enabled ongoing attacks. CISA added all three flaws to its Known Exploited Vulnerabilities catalog and urged immediate remediation.

Arista fixes critical VeloCloud Orchestrator flaw

🔒 Arista has released patches for a critical vulnerability in VeloCloud Orchestrator (VCO) that is actively being exploited in the wild. The vendor warned the flaw may allow remote attackers to access privileged internal functionality and impact VCO hosts, affecting confidentiality, integrity, and availability. Customers are urged to upgrade to fixed releases (VCO 5.2.3.14+, 6.1.3.4+, 6.4.2.4+) and to consider incident response actions such as credential rotation and device validation. Advisors stressed the severity—an unauthenticated command‑injection in an orchestration platform—and warned that on‑premises users often receive fixes more slowly than cloud deployments.

Check Point issues fixes for actively exploited flaw

🛡️ Check Point released security updates for Security Management and Multi-Domain Management products to address multiple vulnerabilities, including a critical authentication bypass (CVE-2026-16232) actively exploited in the wild. The flaw enables unauthenticated attackers to obtain a SmartConsole login token and gain full administrative privileges if Management is exposed to the internet without Trusted Client or firewall restrictions. Additional patches cover two other high-severity issues (CVE-2026-62144 and CVE-2026-62145). Customers are urged to apply the July 22 Jumbo hotfix, restrict Trusted Clients to trusted IPs, and secure Management access with firewall protections.

Eclypsium InfraTrust highlights top infrastructure fixes

🛡️ Eclypsium launched InfraTrust and a monthly InfraTrust Pulse to aggregate vendor infrastructure advisories and guide administrators on which flaws to patch first. The inaugural July 2026 Pulse tracked 61 advisories from 14 vendors, flagging six critical advisories and 26 remotely exploitable, unauthenticated vulnerabilities. The report emphasizes prioritizing flaws by exploitability, exposure, and real-world risk rather than CVSS alone.

OpenSSL HollowByte memory-exhaustion flaw analysis

🛡️ OpenSSL received a silent June fix for a denial-of-service issue Okta branded "HollowByte," which causes servers to allocate up to 131 KB per TLS ClientHello before the body arrives. The bug lets attackers exhaust connections and, on glibc systems, fragment the heap so freed memory remains resident until process restart. Fixed releases are 4.0.1, 3.6.3, 3.5.7, 3.4.6, and 3.0.21 dated June 9, but OpenSSL chose to treat the change as a "bug or hardening" without a CVE, advisory, or changelog note.

FBI warns Russian actors stealing Signal backup keys

🔐 The FBI and CISA warn that Russian-linked threat actors have shifted phishing tactics to steal Signal Backup Recovery Keys, enabling access to users' historical messages. The campaign, tracked as UNC5792 and UNC4221, targets high-value individuals including officials, journalists, and military personnel. Attackers impersonate Signal support, trick users into enabling backups and then request the recovery key to restore data to attacker-controlled devices. Authorities advise that official support never asks for codes or recovery keys and recommend reporting incidents to the FBI or CISA.

CISA urges hardening of Fortinet devices after breaches

🔒 CISA warns that malicious actors have targeted internet-accessible Fortinet devices using compromised credentials, a campaign dubbed FortiBleed affecting roughly 74,000 devices including firewalls and VPN gateways. The agency urges immediate actions such as terminating active SSL VPN and administrative sessions, resetting credentials, enforcing strong password policies, and ensuring secure credential storage using PBKDF2. Organizations should review logs for suspicious activity, enable phishing-resistant MFA for remote and administrative access, and restrict management interfaces from public internet exposure.
