Weaponization speed

5 daysto first PoC

Weaponized quickly — attackers prioritized this vulnerability. Patch urgently.

Recommendation: Plan a near-term fix — a public PoC already exists.

The management tool in MyLittleAdmin 3.8 allows remote attackers to execute arbitrary code because machineKey is hardcoded (the same for all customers' installations) in web.config, and can be used to send serialized ASP code.
