Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates reflected XSS by filtering information outputs to neutralize untrusted input before web page generation.
Validates and sanitizes attacker-controlled inputs at entry points to prevent malicious JavaScript from being processed and reflected.
Requires timely patching of the td-subscription plugin flaw up to version 1.7.3 to remediate the improper input neutralization vulnerability.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
