Vulnerability details

WWBN AVideo is an open source video platform. In 29.0 and earlier, plugin/AuthorizeNet/processPayment.json.php credits the logged-in user's wallet based only on the attacker-controlled amount POST parameter. The endpoint contains a TODO for real Authorize.Net charging, hardcodes $paymentSuccess = true, and…

then calls YPTWallet::addBalance() without validating any Authorize.Net transaction, webhook signature, hosted payment token, nonce, or server-side payment record. This allows any logged-in user to add arbitrary funds to their own AVideo wallet when the AuthorizeNet and YPTWallet plugins are enabled.

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1657 Financial Theft Impact
Adversaries may steal monetary resources from targets through extortion, social engineering, technical theft, or other methods aimed at their own financial gain at the expense of the availability of these resources for victims.
Why these techniques?

Logic flaw in public payment endpoint allows arbitrary wallet balance manipulation (financial theft) via unauthenticated transaction data.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-345

Directly requires independent verification of matching output before adverse decisions, mitigating insufficient authenticity checks on data from external sources.

addresses: CWE-345

Use of approved PKI certificates provides verifiable data authenticity and origin for communications and artifacts.

addresses: CWE-345

Mandates provision of authenticity and integrity artifacts that enable verification of name/address resolution data.

addresses: CWE-345

Requires explicit verification of data authenticity from authoritative sources, preventing acceptance of unauthenticated resolution responses.

addresses: CWE-345

Control requires verification of data authenticity/integrity (e.g., checksums) after aggregation/packing, directly reducing exploitation of insufficient verification before transmission.

addresses: CWE-345

Time synchronization supports reliable freshness verification when checking data authenticity across systems or components.

addresses: CWE-345

Mandates verification of data authenticity for software, firmware, and information.

addresses: CWE-345

Provenance documentation and monitoring directly enables verification of authenticity for components and data throughout their history.
