🔴 A critical out-of-bounds write vulnerability (CVE-2025-9242) in WatchGuard Fireware OS could allow remote code execution via IKEv2 mobile VPN and Branch Office VPN when configured with dynamic gateway peers. Affected releases include Fireware OS 11.10.2 through 11.12.4_Update1, 12.0 through 12.11.3 and 2025.1, and WatchGuard warns devices previously configured with these peers may remain vulnerable. Shadowserver estimates over 71,000 potentially exposed devices; WatchGuard and the US NVD have published advisories and guidance, and a temporary workaround plus narrower BOVPN access policies are recommended if immediate upgrades are not possible.

⚠️ Nearly 76,000 WatchGuard Firebox network appliances exposed on the public internet remain vulnerable to CVE-2025-9242, a critical (9.3) out-of-bounds write in the iked process that handles IKEv2 VPN negotiations. The flaw can be exploited without authentication by sending specially crafted IKEv2 packets to devices configured with dynamic gateway peers, potentially enabling remote code execution. WatchGuard has published patched releases and urges administrators to upgrade to supported versions immediately; 11.x is end-of-support and will not receive fixes.

⚠️Microsoft patched a critical ASP.NET Core vulnerability in the built‑in Kestrel web server and assigned it a CVSS score of 9.9, the highest rating the vendor has ever issued. Tracked as CVE-2025-55315, the flaw enables authenticated attackers to use HTTP request smuggling to bypass security checks and could allow actions such as logging in as another user, bypassing CSRF protections, or performing injection attacks. Microsoft advises updating affected runtimes or rebuilding and redeploying self‑contained apps, while noting that reverse proxies or gateways may already mitigate exposure.

⚠️Threat actors exploited a Cisco SNMP vulnerability (CVE-2025-20352) to achieve remote code execution on legacy IOS XE switches and install custom, largely fileless Linux rootkits that hook into the IOSd memory space, set universal passwords (including one containing 'Disco'), and hide processes and network activity. The rootkits spawn a UDP-based controller to toggle or zero logs, bypass access controls, and reset running-config timestamps to mask changes. Trend Micro also observed spoofed IP/MAC addresses and attempts to combine a retooled Telnet memory-access exploit to deepen persistence.

🔒 Researchers disclosed a recently patched critical vulnerability in WatchGuard Fireware (CVE-2025-9242, CVSS 9.3) that can allow unauthenticated attackers to execute arbitrary code via an out-of-bounds write in the iked process. The flaw affects multiple Fireware branches, including 11.10.2 through 11.12.4_Update1 (EOL noted for 11.x), 12.0 through 12.11.3 and 2025.1, and has been fixed across several updates such as 2025.1.1 and 12.11.4. Administrators are urged to apply the vendor updates immediately, limit internet exposure of VPN interfaces, and follow vendor mitigation guidance until patches are deployed.

🔒 Gladinet released an urgent update for its CentreStack business solution to fix a local file inclusion flaw tracked as CVE-2025-11371, which was abused in the wild as a zero-day. The LFI allowed attackers to read Web.config, extract the ASP.NET machine key, and then leverage a prior deserialization RCE (CVE-2025-30406) to achieve remote code execution. Administrators should upgrade to CentreStack version 16.10.10408.56683 immediately; if patching is not possible, disable the temp handler in Web.config for the UploadDownloadProxy component as a temporary mitigation.

🚨 CISA has added a maximum-severity vulnerability in Adobe Experience Manager (AEM) Forms to its Known Exploited Vulnerabilities Catalog after confirming active exploitation. Tracked as CVE-2025-54253, the flaw is an authentication bypass via Struts DevMode that can result in unauthenticated remote code execution on AEM JEE 6.5.23 and earlier. Adobe released fixes on August 9 after public proof-of-concept code appeared; CISA requires federal agencies to remediate by November 5 and urges all organizations to prioritize patching, apply vendor mitigations, or restrict Internet access to affected AEM Forms deployments.

⚠️ Siemens disclosed a type confusion vulnerability (CVE-2025-6554) affecting HyperLynx and Industrial Edge App Publisher, which can enable remote arbitrary read/write and potential code execution via crafted HTML. The issue carries a CVSS v4 base score of 7.0 and a v3.1 score up to 8.1 depending on context. Siemens has released v1.23.5 for App Publisher; no fix is available yet for HyperLynx. Organizations should restrict network exposure, isolate control systems, use secure remote access, and follow Siemens and CISA guidance to mitigate risk.

🔒 Siemens' Solid Edge CAD applications contain multiple vulnerabilities in PRT file parsing—two out‑of‑bounds writes (CWE‑787) and two out‑of‑bounds reads (CWE‑125)—tracked as CVE‑2025‑40809 through CVE‑2025‑40812. Affected releases include SE2024 versions prior to V224.0 Update 14 and SE2025 versions prior to V225.0 Update 6. Exploitation could crash the application or enable code execution in the context of the current process; Siemens and CISA recommend applying the listed updates, avoiding untrusted PRT files, and limiting network exposure.

🛡️ Researchers disclosed a campaign, Operation Zero Disco, that exploited a recently patched SNMP stack overflow (CVE-2025-20352) in Cisco IOS and IOS XE devices to deploy Linux rootkits on older, unprotected switches. The attackers achieved remote code execution and persistence by installing hooks into IOSd memory and setting universal passwords that include the string "disco." Targets included legacy 3750G and 9300/9400 series devices lacking EDR protections.

⚠ Adobe's Experience Manager (AEM) has a critical misconfiguration—CVE-2025-54253—scored 10.0 and added to CISA's KEV after evidence of active exploitation. The flaw exposes the /adminui/debug servlet, which evaluates OGNL expressions without authentication, enabling arbitrary code execution via a single crafted HTTP request. Adobe addressed the issue in 6.5.0-0108; affected organizations should apply updates immediately and FCEB agencies must remediate by November 5, 2025.

🔒 Claroty Team82 disclosed two critical vulnerabilities (CVE-2023-40151 and CVE-2023-42770) affecting Red Lion Sixnet SixTRAK and VersaTRAK RTUs, both rated 10.0 on the CVSS scale. One flaw is an authentication bypass that accepts unauthenticated TCP messages on port 1594; the other enables remote shell execution via the Sixnet Universal Driver (UDR), allowing commands to run as root. Chaining the issues permits unauthenticated remote root code execution, creating substantial risk to industrial automation. Users are advised to apply vendor patches, enable and correctly configure authentication, and block TCP access to affected devices immediately.

🔒 Researchers warn of a critical unauthenticated command injection in ICTBroadcast (CVE-2025-2611, CVSS 9.3) that allows attackers to inject shell commands via the BROADCAST session cookie. Exploits observed since October 11 used a time-based probe followed by Base64-encoded payloads to establish reverse shells. Approximately 200 internet-facing instances running versions 7.4 and earlier appear exposed; vendor comment and patch status remain unclear.

🔒 SAP has released security updates addressing 13 vulnerabilities, including a maximum-severity insecure deserialization flaw in NetWeaver AS Java (CVE-2025-42944, CVSS 10.0) that can lead to arbitrary OS command execution via the RMI‑P4 module. The vendor's latest patch adds a JVM-wide serial filter (jdk.serialFilter) to block dangerous classes and packages — a list curated with the ORL and recommended by security firm Onapsis — and complements an earlier remediation issued last month. Other critical fixes include a directory traversal in SAP Print Service (CVE-2025-42937, 9.8) and an unrestricted file upload in SAP Supplier Relationship Management (CVE-2025-42910, 9.0); administrators are urged to apply patches and mitigations immediately.

🔒 Microsoft’s October Patch Tuesday addresses 167 vulnerabilities, including seven rated critical that require immediate CISO attention. Notable fixes include a 9.8 RCE in Windows Server Update Service (WSUS) (CVE-2025-59287) and two Office RCEs exploitable via the Preview Pane. Two legacy Agere modem driver flaws include an in-the-wild zero day and a prior public disclosure, prompting Microsoft to remove ltmdm64.sys from Windows. Administrators should prioritize internet-facing services, kernel-mode drivers, and review WSUS exposure and patch management architecture.

⚠️ Oracle released an emergency security alert on October 11 for CVE-2025-61884, a 7.5 CVSS information-disclosure flaw in the Runtime UI component of E-Business Suite (versions 12.2.3–12.2.14). The vulnerability allows unauthenticated remote attackers with network access to steal sensitive data. The patch arrives one week after an emergency fix for a Cl0p-exploited RCE, and experts urge administrators to apply updates, hunt for prior compromise, and restrict outbound traffic from EBS servers.

🔒 Microsoft’s October 2025 Patch Tuesday addresses 172 vulnerabilities, including two publicly disclosed issues, three zero‑day flaws and eight Critical CVEs. The bulk of fixes target Windows (134 patches), Microsoft Office (18) and Azure (6), with elevation-of-privilege and remote code execution as the primary risks. Windows 10 reaches end of life on October 14, 2025; hosts must be on 22H2 to receive Extended Security Updates. CrowdStrike recommends prioritizing patches for actively exploited zero‑days and using Falcon Exposure Management dashboards to track and remediate affected systems.

🔒 Microsoft is restricting access to Internet Explorer mode in Edge after discovering attackers leveraged an unpatched zero-day in the Chakra JavaScript engine combined with social engineering to achieve remote code execution and privilege escalation. The company removed quick UI triggers (toolbar button, context menu, hamburger items) so IE mode now requires explicit configuration under Settings > Default Browser. Commercial, policy-managed deployments remain unaffected.

⚠️ Huntress has observed criminals exploiting a new zero-day (CVE-2025-11371) in Gladinet CentreStack and Triofox file-sharing servers that enables unauthenticated local file inclusion. The flaw can expose the application's Web.config machineKey, effectively re-enabling a prior ViewState deserialization RCE (CVE-2025-30406). Gladinet has not yet released a patch; Huntress advises disabling the UploadDownloadProxy temp handler as a mitigation. Huntress detected misuse across multiple customers and notes that SOC telemetry flagged irregular base64 payloads; administrators should assume 'fully patched' may not equal secure and isolate or disable vulnerable handlers until a vendor patch is available.

🔒 Microsoft has tightened access to Internet Explorer mode in Edge after credible reports in August 2025 that unknown actors abused the legacy compatibility feature to compromise devices. Attackers used social engineering to coerce users into reloading pages in IE mode and then chained unpatched Chakra JavaScript engine exploits to gain remote code execution and elevate privileges. Microsoft removed the IE mode toolbar button, context-menu and hamburger-menu entries; IE mode must now be enabled explicitly via Edge settings and sites must be added to an IE mode pages list.
