CVE-2025-70957
HighSummary
W serwerze TON Lite przed wersją 2024.09 odkryto podatność typu Denial of Service (DoS). Problem wynika z obsługi zewnętrznych argumentów przekazywanych do lokalnie wykonywanych 'metod get', co pozwala atakującemu na wstrzyknięcie złośliwego obiektu Continuation, co prowadzi do nadmiernego zużycia zasobów CPU.
Risk Assessment
Atakujący może zmonopolizować moc obliczeniową serwera Lite, co znacząco obniża jego wydajność i powoduje odmowę usługi dla legalnych użytkowników korzystających z bramki.
Recommendation
Zaleca się aktualizację serwera TON Lite do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie obciążenia CPU w celu wykrywania potencjalnych ataków DoS.

Original NVD description (English source)
A Denial of Service (DoS) vulnerability was discovered in the TON Lite Server before v2024.09. The vulnerability arises from the handling of external arguments passed to locally executed "get methods." An attacker can inject a constructed Continuation object (an internal TVM type) that is normally restricted within the VM. When the TVM executes this malicious continuation, it consumes excessive CPU resources while accruing disproportionately low virtual gas costs. This "free" computation allows an attacker to monopolize the Lite Server's processing power, significantly reducing its throughput and causing a denial of service for legitimate users acting through the gateway.
