Remediation Priorities

Immediate Action Required (Critical — Patch/Mitigate Now)

1. Cisco IMC (CVE-2026-20093) — Restrict management interface network access; apply Cisco security advisory patches immediately. MITRE ATT&CK: T1078 (Valid Accounts).
2. Cisco SSM On-Prem (CVE-2026-20160) — Block external access to internal service API ports; apply vendor patch. MITRE ATT&CK: T1190 (Exploit Public-Facing Application).
3. MetInfo CMS (CVE-2026-29014) — Take affected instances offline or apply WAF rules blocking PHP injection patterns until patch is available. MITRE ATT&CK: T1190, T1059.003.
4. XenForo (CVE-2025-71279, CVE-2025-71281) — Upgrade to XenForo 2.3.7+ immediately. MITRE ATT&CK: T1556 (Modify Authentication Process).

Short-Term (High — Patch Within 7 Days)

1. Google Chrome (CVE-2026-5282) — Update Chrome to 146.0.7680.178 or later across all endpoints. MITRE ATT&CK: T1203 (Exploitation for Client Execution).
2. IBM Storage Protect Server (CVE-2025-13855) — Apply IBM security patch; enforce parameterized queries. MITRE ATT&CK: T1190.
3. Cisco EPNM (CVE-2026-20155) — Apply Cisco advisory patch; audit REST API access controls. MITRE ATT&CK: T1078.003.
4. ByteDance Deer-Flow (CVE-2026-34430) — If using Deer-Flow in production AI pipelines, restrict bash tool access and apply upstream patch. MITRE ATT&CK: T1059.004 (Unix Shell).
5. Cisco IMC (CVE-2026-20094) — Limit read-only user permissions and apply patch; enforce command execution auditing. MITRE ATT&CK: T1059.

Long-Term Recommendations

• Implement network segmentation to isolate Cisco management interfaces (IMC, SSM, EPNM).
• Enforce browser update policies via MDM/endpoint management to address recurring Chrome renderer CVEs.
• Audit all XenForo installations and enforce a minimum supported version policy (2.3.9+).
• Review all SQL-accepting input parameters in internally developed applications against parameterized query standards (OWASP A03:2021).
• Evaluate libinput deployments and restrict Lua bytecode execution paths where applicable.
