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.

portlets/contact/ref/refContactDetail.do in Accela Civic Platform through 20.1 allows remote attackers to obtain sensitive information via a modified contactSeqNumber value. NOTE: the vendor states "the information that is being queried is authorized for an authenticated user of that application, so we consider this not applicable.
