Security readout for executives and security teams
CVE-2013-2251 lets unauthenticated remote attackers make vulnerable Apache Struts applications evaluate attacker-controlled OGNL expressions. In business terms, a public-facing affected application could be taken over, exposing data, integrity, and availability. CISA KEV presence means known exploitation has occurred, so legacy Struts exposure should be treated as urgent. Highest exposure is internet-facing Java web applications running Apache Struts 2.0.0 through 2.3.15, plus vendor products that bundled affected Struts components. The source bundle does not provide complete CPE coverage, so exposure must be confirmed through software inventory and vendor advisories. Treat this as a critical legacy-exposure item. Because KEV confirms known exploitation and the flaw can lead to application takeover, executives should require rapid inventory confirmation, remediation ownership, and exception tracking for any affected system that cannot be fixed promptly. Mitigation focus: Identify all Apache Struts deployments and versions, including bundled copies in vendor products.; Apply Apache and vendor guidance for CVE-2013-2251 or S2-016 immediately.; Prioritize internet-facing and authentication-adjacent applications first..

Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
