Classification: Critical, Solution: Official Fix, Exploit Maturity: Proof-of-Concept, CVSSv3.1: 9.8, CVEs: , Summary: AnyDesk before 8.0.3 allows unauthenticated remote attackers to execute arbitrary code via a heap-based buffer overflow, as demonstrated on Linux for command execution as root without the victim approving desktop control. In the stream packet handler for mode 5 in the session protocol, a payload length value is not validated.
Disponibile un Proof of Concept (PoC) per lo sfruttamento della CVE-2026-109390 - già sanata dal vendor - presente in AnyDesk per sistemi Linux, nota soluzione per l’accesso, il supporto e il controllo remoto dei dispositivi tramite connessioni di rete. Tale vulnerabilità, qualora sfruttata, potrebbe consentire ad un attaccante remoto non autenticato di eseguire codice arbitrario con privilegi elevati sui sistemi interessati.
Threat actors exploited Samsung MagicINFO to install AnyDesk, disable Defender, and compile a Monero miner directly on a victim endpoint. Learn the detection signals.
This vulnerability allows local attackers to create a denial-of-service condition on affected installations of AnyDesk. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The ZDI has assigned a CVSS rating of 4.7. The following CVEs are assigned: CVE-2026-15681.
