Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SC-23 Session Authenticity good match

prevent

SC-23 enforces session authenticity mechanisms such as CSRF tokens, directly preventing forged requests from tricking authenticated users into unauthorized actions.

SI-10 Information Input Validation good match

prevent

SI-10 requires validation of information inputs, including anti-CSRF tokens, to block malicious requests exploiting the plugin's lack of CSRF protection.

SI-2 Flaw Remediation good match

prevent

SI-2 mandates timely remediation of identified flaws, directly addressing this CVE by patching the vulnerable frontpage-category-filter plugin.
