🔔 On December 4, 2025, CISA published nine Industrial Control Systems advisories addressing vulnerabilities in products from Mitsubishi Electric, MAXHUB, Johnson Controls, Sunbird, SolisCloud, and Advantech. The release also includes updated advisories for Consilium Safety CS5000 and Johnson Controls FX families. Each advisory provides technical details, affected versions, and recommended mitigations. Administrators are encouraged to review the advisories and apply vendor guidance promptly.

🔒 Johnson Controls reported a Direct Request (Forced Browsing) vulnerability (CVE-2025-26381) in the OpenBlue Mobile Web Application for OpenBlue Workplace. Versions 2025.1.2 and earlier may allow remote attackers to gain unauthorized access to sensitive information; CISA cites a CVSS v3.1 score of 9.3 and a CVSS v4 score of 6.5. Johnson Controls recommends upgrading to patch level 2025.1.3 when available; until then, administrators should disable the mobile app in IIS or use the primary Workplace web interface as a mitigation.

🔒 CISA, NSA, and the Canadian Centre for Cyber Security released a joint malware analysis on BRICKSTORM, a sophisticated backdoor targeting VMware vSphere (vCenter) and Windows environments used by PRC state-sponsored actors. The report provides indicators of compromise (IOCs), detection signatures, and CISA-developed YARA and SIGMA rules to help critical infrastructure owners identify compromises. Recommended mitigations include scanning with the provided rules, inventorying and monitoring edge devices, enforcing network segmentation, and adopting Cross-Sector Cybersecurity Performance Goals; organizations are urged to report suspected activity to CISA immediately.

🛡️ CISA, NSA, and the Canadian Centre for Cyber Security report that PRC state-sponsored actors deployed the BRICKSTORM backdoor to gain long-term persistence on VMware vSphere (vCenter/ESXi) and Windows hosts. The analysis of eight samples includes YARA and Sigma detection content plus scanning guidance for vCenter filesystems and SIEMs. Organizations should apply the provided IOCs and detection signatures, hunt for modified init scripts, DoH resolver requests, and hidden API endpoints, and report any findings immediately.

🔒 CISA warns that Mitsubishi Electric GX Works2 contains a cleartext storage vulnerability (CVE-2025-3784) that can expose credentials stored in project files. The issue affects all versions and may allow a local attacker with file access to open password-protected projects and read or modify project data. A vendor fix is under development; organizations should restrict access, block untrusted remote logins, and follow the mitigations recommended by Mitsubishi Electric and CISA.

🔒 CISA warns of two critical vulnerabilities in Sunbird DCIM dcTrack and Power IQ appliances that could enable unauthorized access or credential theft. One is an authentication bypass via alternate remote-access channels (CVE-2025-66238); the other involves hard‑coded/default credentials (CVE-2025-66237) with a CVSS v4 high score of 8.4. Sunbird has released fixes (dcTrack 9.2.3, Power IQ 9.2.1); until systems are updated, CISA recommends restricting SSH and nonessential ports, changing deployment passwords, isolating control networks behind firewalls, and using secure VPNs for remote access.

🚨 A weak password recovery mechanism in MAXHUB Pivot client allows remote attackers to request password resets and potentially take over accounts. MAXHUB reports all Pivot client versions prior to v1.36.2 are affected and has released v1.36.2 to address the issue. CISA assigned CVE-2025-53704 and rates the flaw high severity (CVSS v4 8.7) with low attack complexity. Administrators should apply the update and follow recommended network-segmentation and access controls to reduce exposure.

🔒 Johnson Controls reported an improper validation of certificate expiration in iSTAR access control panels that can prevent devices from re-establishing communication when the default certificate expires. The flaw, tracked as CVE-2025-61736, carries a CVSS v4 base score of 7.1 and a CVSS v3.1 score of 6.5. Affected units are those running versions prior to TLS 1.2. Recommended mitigations include deploying host-based certificates, migrating clusters to TLS 1.3 (requires firmware/C•CURE updates), or upgrading legacy panels to G2 hardware.

⚠️ Advantech iView versions 5.7.05.7057 and earlier are affected by an SQL injection vulnerability in SNMP v1 trap handling (port 162) that can be exploited remotely with low attack complexity. CISA assigns CVE-2025-13373 with a CVSS v4 base score of 8.7 (and CVSS v3.1 7.5). Successful exploitation could disclose, modify, or delete data. Advantech recommends updating to iView v5.8.1; CISA advises network isolation, firewalls, and secure remote access.

⚠️ Developers must immediately upgrade React 19 and affected frameworks such as Next.js after researchers at Wiz disclosed a critical deserialization vulnerability in the React Server Components (RSC) Flight protocol that can enable remote code execution. The flaw exists in default configurations and impacts React 19.0.0, 19.1.0, 19.1.1 and 19.2.0, while Next.js 15.x and 16.x App Router deployments received a related CVE. Upgrade to the latest vendor-recommended releases now and follow the React blog's guidance.

⚠️Researchers from CheckPoint disclosed a critical remote code execution vulnerability in OpenAI's Codex CLI that allowed project-local .env files to redirect the CODEX_HOME environment variable and load attacker-controlled MCP servers. By adding a malicious mcp_servers entry in a repo-local .codex/config.toml, an attacker with commit or PR access could cause Codex to execute commands silently whenever a developer runs the tool. OpenAI addressed the issue in Codex CLI v0.23.0 by blocking project-local redirection of CODEX_HOME, but the flaw demonstrates how automated LLM-powered developer tools can expand the attack surface and enable persistent supply-chain backdoors.

🔒 Meta and Vercel disclosed a critical remote code execution vulnerability in React Server Components (CVE-2025-55182) that also affected some Next.js releases. Google Cloud rolled out a preconfigured Cloud Armor WAF rule (cve-canary), is enforcing protections for Firebase Hosting, and recommends testing the rule in preview while enabling ALB request logging to consume telemetry. Customers should promptly update dependencies to React 19.2.1 and the patched Next.js releases and redeploy services to remove the vulnerability.

⚠️ A critical privilege-escalation vulnerability (CVE-2025-8489) in the King Addons for Elementor plugin is being actively exploited to create administrative accounts during registration. Attacks began on October 31, a day after public disclosure, and Wordfence reports blocking more than 48,400 exploit attempts. Site owners should upgrade to King Addons 51.1.35 immediately and check logs for suspicious IPs and unexpected admin accounts.

🚨 A maximum-severity remote code execution vulnerability in React Server Components (CVE-2025-55182, CVSS 10.0) allows unauthenticated attackers to execute arbitrary JavaScript by sending crafted payloads to Server Function endpoints. Affected npm packages include react-server-dom-webpack, react-server-dom-parcel, and react-server-dom-turbopack in specific 19.x releases; fixes are available in 19.0.1, 19.1.2, and 19.2.1. The issue also impacts Next.js (CVE-2025-66478, CVSS 10.0) across multiple releases and has been patched in a series of 15.x and 16.x updates. Security firm Wiz reports roughly 39% of cloud environments host vulnerable instances; apply patches immediately.

🔒 Microsoft has quietly fixed CVE-2025-9491, a Windows Shortcut (.LNK) UI misinterpretation flaw that enabled remote code execution and has been abused since 2017 by multiple state-affiliated and criminal groups. The change, deployed in November 2025, forces the Properties dialog to display the full Target command string regardless of length, removing the truncation that hid malicious arguments. Vendors including 0patch and ACROS Security noted alternative mitigations — a UI change by Microsoft and a warning-based micropatch — that together reduce user exposure.

⚠️ A critical privilege-escalation vulnerability in the King Addons plugin for Elementor (CVE-2025-8489, CVSS 9.8) is being actively exploited to create administrative accounts. The flaw stems from an insecure handle_register_ajax() implementation that permits unauthenticated users to specify the administrator role during registration via the "/wp-admin/admin-ajax.php" endpoint. A patch is available in version 51.1.35 (released September 25, 2025); administrators should update immediately and audit for unauthorized admin users.

🔒 Microsoft has quietly mitigated a high-severity Windows LNK vulnerability tracked as CVE-2025-9491, which attackers used to hide malicious command-line arguments inside .lnk files. The flaw relied on padding the Target field so Windows previously masked arguments beyond 260 characters, enabling persistence and malware delivery. Microsoft’s November update now shows the full Target string in Properties but does not remove malicious arguments or warn users. An unofficial 0Patch micropatch limits target strings and warns on unusually long values.

🚨 CISA added CVE-2021-26828 — an OpenPLC ScadaBR unrestricted file upload vulnerability — to its Known Exploited Vulnerabilities (KEV) Catalog after evidence of active exploitation. The flaw allows dangerous file types to be uploaded, a frequent attack vector that poses significant risks to federal networks. Under BOD 22-01 federal agencies must remediate cataloged CVEs by required dates; CISA also urges all organizations to prioritize remediation.

⚠️ Picklescan, a Python pickle scanner, has three critical flaws that can be abused to execute arbitrary code when loading untrusted PyTorch models. Discovered by JFrog researchers, the issues — a file-extension bypass (CVE-2025-10155), a ZIP CRC bypass (CVE-2025-10156) and an unsafe-globals bypass (CVE-2025-10157) — let attackers present malicious models as safe. The vulnerabilities were responsibly disclosed on June 29, 2025 and fixed in Picklescan 0.0.31 on September 9; users should upgrade and review model-loading practices and downstream automation that accepts third-party models.

🛡️ Cloudflare has deployed new WAF protections to mitigate a high‑severity RCE in React Server Components (CVE-2025-55182). All customers whose React traffic is proxied through the Cloudflare WAF are automatically protected — the rules are included in both the Free Managed Ruleset and the standard Managed Ruleset and default to Block. Rule IDs: Managed Ruleset 33aa8a8a948b48b28d40450c5fb92fba and Free Ruleset 2b5d06e34a814a889bee9a0699702280; Cloudflare Workers are immune. Customers on paid plans should verify Managed Rules are enabled and update to React 19.2.1 and the recommended Next.js releases (16.0.7, 15.5.7, 15.4.8).
