⚠️ Mandiant Threat Defense observed active exploitation of an unauthenticated access control vulnerability in Gladinet's Triofox (CVE-2025-12480) that allowed attackers to bypass authentication and reach administrative setup pages. By manipulating the HTTP Host header to impersonate localhost, attackers accessed protected admin workflows, created a native admin account, and configured the built-in anti‑virus engine to execute a malicious script as SYSTEM. The chain led to a PowerShell downloader, installation of a legitimate Zoho UEMS agent, and deployment of remote access tools; the vulnerability affected Triofox 16.4.10317.56372 and was mitigated in 16.7.10368.56560. Operators should upgrade immediately, audit admin accounts, and restrict anti‑virus engine paths.

🔒 Cisco has released security updates for Unified Contact Center Express (CCX) to address two critical vulnerabilities that can enable authentication bypass and remote code execution as root. The company issued software updates 15.0 ES01 and 12.5 SU3 ES07 and urged customers to apply them immediately. Cisco also fixed four medium-severity issues across CCX, CCE and UIC, and warned of a new attack variant affecting ASA and FTD devices tied to earlier patches.

🔒 Cisco has released updates to address a critical vulnerability in Unified Contact Center Express (UCCX) — CVE-2025-20354 — found in the Java RMI process that can let unauthenticated attackers execute arbitrary commands as root.

Administrators should upgrade to the first fixed releases (12.5 SU3 ES07 or 15.0 ES01) immediately; Cisco has not yet observed active exploitation.

⚠️ A critical remote-code execution vulnerability in @react-native-community/cli and its cli-server-api component lets attackers run arbitrary OS commands via the Metro development server. The flaw stems from a /open-url endpoint that forwards a supplied URL directly to the open() package and, despite console messages, the server can bind to 0.0.0.0 rather than localhost. JFrog demonstrated Windows exploitation and the issue is fixed in cli-server-api version 20.0.0; users should update or bind the server to 127.0.0.1.

⚠️ Advantech DeviceOn/iEdge versions 2.0.2 and earlier contain multiple remotely exploitable vulnerabilities, including XSS and several path-traversal flaws assigned CVE-2025-64302, CVE-2025-62630, CVE-2025-59171, and CVE-2025-58423. Successful exploitation may lead to denial-of-service, arbitrary file disclosure, or remote code execution with system-level permissions. CISA notes the products are EOL and recommends upgrading to DeviceOn, isolating devices from the internet, and using secure remote access methods to reduce risk.

⚠ ABB FLXeon devices are affected by multiple high-severity vulnerabilities, including hard-coded credentials, MD5 password hashing without proper salt, and improper input validation that can enable remote code execution. Combined CVSS v4 scores reach up to 8.7 and successful exploitation could allow remote control, arbitrary code execution, or device crashes. ABB and CISA advise disconnecting Internet-exposed units, applying the latest firmware, enforcing physical access controls, and using secure remote-access methods such as properly configured VPNs.

⚠️ A critical vulnerability in the popular Post SMTP WordPress plugin, which has more than 400,000 active installations, allowed unauthenticated attackers to read email logs — including password reset messages — and change any user password, enabling full account and site takeover. Wordfence reported active exploitation and urged immediate updates after detecting thousands of automated attacks. Administrators should install the patched release or disable the plugin immediately to prevent compromise.

⚠️ CISA warns that a critical remote command execution vulnerability, tracked as CVE-2025-48703, is being exploited in the wild against CentOS Web Panel (CWP). The flaw impacts all CWP versions before 0.9.8.1204 and allows unauthenticated attackers who know a valid username to inject shell commands via the file-manager changePerm t_total parameter. The vendor fixed the issue in 0.9.8.1205, and federal agencies have until Nov 25 under BOD 22-01 to remediate or stop using the product.

🔒Anthropic's official Claude Desktop extensions for Chrome, iMessage and Apple Notes were found vulnerable to web-based prompt injection that could enable remote code execution. Koi Security reported unsanitized command injection in the packaged Model Context Protocol (MCP) servers, which run unsandboxed on users' devices with full system permissions. Unlike browser extensions, these connectors can read files, execute commands and access credentials. Anthropic released a fix in v0.1.9, verified by Koi Security on September 19.

⚠ A critical vulnerability in the @react-native-community/cli ecosystem could let remote, unauthenticated attackers execute arbitrary OS commands on machines running the React Native development server. JFrog researcher Or Peles reported that the Metro dev server binds to external interfaces by default and exposes a vulnerable /open-url endpoint that passes user input to the unsafe open() call. The flaw (CVE-2025-11953, CVSS 9.8) affected versions 4.8.0–20.0.0-alpha.2 and is fixed in 20.0.0.

🔒 An argument injection vulnerability (CWE-88) in ICM Viewer v1.6.0.10 (CVE-2025-12556) could allow remote attackers to execute arbitrary code on the host system. CISA assigns a CVSS v3 score of 8.8 and a CVSS v4 score of 8.7, noting remote exploitability with low attack complexity and limited privileges required. IDIS requires immediate upgrade to v1.7.1 or uninstallation; Claroty Team82 researchers reported the issue and CISA reports no known public exploitation to date.

🔒 Microsoft has issued updates to address three previously unknown flaws in the Windows Graphics Device Interface (GDI) that could permit remote code execution and information disclosure. The issues, rooted in malformed EMF/EMF+ records, cause out-of-bounds memory access in GdiPlus.dll and gdi32full.dll during image rendering, thumbnailing and print initialization. Patches were released across the May, July and August 2025 Patch Tuesdays (KB5058411, KB5062553, KB5063878); administrators should apply updates promptly and avoid opening untrusted EMF files.

🔒 Sophos researchers discovered China-linked espionage group Bronze Butler exploiting a zero-day in Motex Lanscope Endpoint Manager (CVE-2025-61932) to deploy an updated Gokcpdoor backdoor. The flaw enabled unauthenticated remote code execution as SYSTEM on affected versions (<=9.4.7.2), and attackers used OAED Loader, DLL sideloading, and multiplexed C2 channels to evade detection. Motex released patches on October 20, 2025, and CISA added the vulnerability to its KEV list; organizations are advised to upgrade immediately since no mitigations exist.

⚠️ King Addons for Elementor, installed on over 10,000 WordPress sites, contains two unauthenticated critical vulnerabilities that can enable full site takeover. Patchstack identified an arbitrary file upload (CVE-2025-6327) and a registration-based privilege escalation (CVE-2025-6325) that allow remote attackers to place files in web-accessible directories and create administrative accounts. The vendor released version 51.1.37 to add a role allowlist, input sanitization, upload permission checks and stricter file-type validation — administrators should update immediately and verify whether the 'King Addons Login | Register Form' widget is active.

🔒 A critical Chrome zero-day (CVE-2025-2783) has been actively exploited in a targeted espionage operation Kaspersky calls "Operation ForumTroll," attributed to the threat actor Mem3nt0 mori. Attackers used highly personalized phishing invites and one-click, short-lived links to deliver a sandbox-escape exploit that enabled code execution in Chrome's browser process. Google moved quickly with fixes in Chrome 134.0.6998.177/.178, while related issues were later patched in Firefox as CVE-2025-2857.

⚠️ Microsoft has released an out-of-band patch for a critical WSUS vulnerability (CVE-2025-59287) that enables unauthenticated remote code execution by sending malicious encrypted cookies to the GetCookie() endpoint. Security vendors Huntress and HawkTrace reported active exploitation of publicly exposed WSUS instances on TCP ports 8530 and 8531. Administrators should prioritize applying the update immediately; if that is not possible, isolate WSUS servers, restrict access to management hosts and Microsoft Update servers, and block inbound traffic to ports 8530/8531 until systems are remediated.

⚠️ A critical unauthenticated remote code execution vulnerability in Microsoft Windows Server Update Services was identified as CVE-2025-59287 and observed being actively exploited in October 2025. The flaw stems from unsafe deserialization in WSUS endpoints (GetCookie and ReportingWebService) and enables remote attackers to execute arbitrary code as SYSTEM. Microsoft issued an emergency out-of-band patch on Oct 23 after initial Patch Tuesday fixes were incomplete; organizations should apply the update or follow temporary mitigations such as disabling the WSUS Server Role or blocking inbound TCP ports 8530/8531 immediately.

🔔 CISA ordered U.S. federal agencies to urgently patch a critical, actively exploited Windows Server Update Services vulnerability (CVE-2025-59287) that enables unauthenticated remote code execution with SYSTEM privileges. Microsoft released out-of-band security updates after proof-of-concept exploit code appeared, and administrators are urged to install them immediately or disable the WSUS Server role as an interim mitigation. Security firms reported scanning and attacks against WSUS instances exposed on default ports 8530/8531, and CISA has added the flaw to its Known Exploited Vulnerabilities catalog, mandating federal patching under BOD 22-01.

⚠️ Microsoft released an out-of-band patch for a critical WSUS remote code execution (CVE-2025-59287) after researchers observed active exploitation that drops a .NET executable and Base64 PowerShell payloads. LockBit has resurfaced with a new multi-platform 5.0 variant claiming victims, while a modified Telegram Android app distributing the Baohuo backdoor has infected tens of thousands of devices. Reporting also shows the F5 breach began in late 2023 and has since widened, underscoring the need for urgent patching and threat hunting.

🔴 Wordfence warns that threat actors are actively exploiting three critical 2024 CVEs in popular WordPress plugins, GutenKit and Hunk Companion, which report more than 40,000 and 8,000 active installations respectively. The vulnerabilities permit unauthenticated attackers to install and activate arbitrary plugins or upload spoofed plugin files, enabling remote code execution (RCE) and straightforward site takeover when exploited or chained with other flaws. Discovered via Wordfence's bug bounty in late September and early October, the campaign reignited on 8 October and the vendor has already blocked nearly 8.8 million exploitation attempts while urging administrators to update or remove affected versions.
