CISA Orders Federal Patch for Zimbra XSS Flaw Exploited

⚠️ CISA has ordered Federal Civilian Executive Branch agencies to remediate an actively exploited stored cross-site scripting vulnerability in the Zimbra Collaboration Suite, tracked as CVE-2025-66376. The flaw in the Classic UI can be abused via CSS @import directives in HTML emails by remote, unauthenticated attackers to execute arbitrary JavaScript, risking session hijack and data exfiltration. Agencies were given until April 1 under BOD 22-01, and all organizations are urged to apply vendor patches or available mitigations immediately.

ConnectWise fixes ScreenConnect signature flaw, critical

🔒 ConnectWise warned customers about a critical cryptographic signature verification bug in ScreenConnect (tracked as CVE-2026-3564) that affects versions prior to 26.1 and can enable unauthorized session authentication and privilege escalation. The vulnerability allows attackers who obtain ASP.NET machine key material to generate or modify protected values the server will accept, potentially resulting in hijacked sessions and elevated access. ConnectWise patched the issue in ScreenConnect 26.1 by adding encrypted storage and improved handling for machine keys; cloud-hosted instances were auto-upgraded while on-premises administrators must upgrade immediately. The vendor reported observed attempts to abuse disclosed machine key material in the wild but has no confirmed evidence of exploitation against ConnectWise-hosted instances and urges responsible disclosure of active findings.

CrackArmor: AppArmor Linux Flaws Allow Local Root Access

🛡️ Qualys TRU has disclosed 'CrackArmor,' a set of nine AppArmor vulnerabilities present since Linux kernel 4.11 (2017). These AppArmor flaws allow local, unprivileged users to manipulate security profiles via kernel pseudo-files, enabling local privilege escalation, container isolation bypass, Denial-of-Service and potential kernel-memory exposure. Qualys developed proof-of-concept exploits but has not publicly released the code to limit risk. Organizations should prioritize applying vendor kernel updates and scanning for affected systems.

Microsoft Probes Classic Outlook Sync and Connection Issues

📧 Microsoft is investigating several issues that are disrupting email synchronization and server connections in the classic Outlook desktop client. One bug causes 'Can't connect to the server' errors when creating groups if Exchange Web Services (EWS) is enabled because an AD Graph validation call fails; Microsoft plans updated group functionality using REST APIs and recommends using the new Outlook or OWA until a fix is released. Separate reports describe 0x800CCC0F and 0x80070057 errors for Gmail and Yahoo accounts after password changes — a temporary workaround is to delete the affected identity registry entries — and a cursor disappearance bug affecting Outlook and some Microsoft 365 apps is also under investigation.

FBI: Phishing Scam Targets City and County Permit Applicants

⚠️ The FBI warns that criminals are impersonating city and county planning and zoning officials to phish businesses and individuals with active land-use or permit applications. Victims receive emails referencing permit details, zoning application numbers, or property addresses and are instructed to pay invoices via wire transfers, peer-to-peer platforms, or cryptocurrency, often pressured with urgency. The agency urges recipients to verify sender domains, call local government offices to confirm fees, and report incidents to the IC3.

UK NCSC Issues Warning on Iranian Cyberattack Risks

⚠️The UK National Cyber Security Centre (NCSC) has issued an advisory warning British organisations of an elevated risk of Iranian cyberattacks amid the ongoing Middle East conflict. While the NCSC says there is not yet a significant change in the direct threat to the UK, state‑sponsored and Iran‑linked actors likely retain some capability despite Iran’s domestic Internet blackout. Organisations with operations or supply chains in the region are urged to follow guidance on DDoS, phishing, and ICS targeting, review external attack surfaces, and increase monitoring.

Microsoft: LNK Shortcut Spoofing Issues Not Considered Bugs

⚠️ Security researcher Wietze Beukema disclosed several techniques at Wild West Hackin' Fest that manipulate Windows .lnk shortcut files to display a benign target in Explorer while executing a different program, including use of malformed LinkTargetIDList and EnvironmentVariableDataBlock fields. These variants can hide command-line arguments and exploit forbidden path characters to show deceptive targets such as "invoice.pdf" while invoking PowerShell or other payloads. Microsoft told the researcher it will not treat the primary finding as a security vulnerability, saying exploitation requires user interaction and pointing to Microsoft Defender, Smart App Control, and built-in warnings for downloaded .lnk files. Beukema published lnk-it-up, an open-source toolkit to generate and detect such shortcuts for testing and research.

The issue is not remotely exploitable; the vendor’s fix is v2.5.2790 or later. Users should review and sanitize logs, rotate proxy credentials, avoid plain-text passwords in proxy URLs, and restrict Event Log Reader privileges.
