Equifax: Unpatched Apache Struts CVE-2017-5638 & Expired SSL Inspection Certificate
Internal patch verification Constraint_Boundary failed. A key Telemetry_Channel (SSL traffic inspection) remained dead for 19 months due to certificate expiration, allowing deep data buffer exfiltration unmonitored.
US-CERT issued an alert for critical remote code execution flaw Apache Struts (CVE-2017-5638) on March 8, 2017. Equifax internal security policy required patching within 48 hours. However, internal IT systems failed to scan the dispute portal, and an internal network traffic inspection tool had an expired SSL certificate for 19 months, blinding security staff while Chinese military hackers exfiltrated records of 147 million Americans for 76 days unobserved.

Contained known remote code execution flaw in HTTP Content-Type header parser
Omitted from internal patch distribution list due to undocumented server asset database
Failed to inspect encrypted outbound exfiltration due to expired security certificate for 19 months
Executed 9,000 queries and exfiltrated SSNs, names, and credit files of 147,000,000 consumers
"Equifax had the tools to detect the breach, but the certificate required to decrypt the traffic had been expired for over a year."
