AI description
CVE-2025-12686 is a critical remote code execution (RCE) vulnerability found in Synology BeeStation devices. It was demonstrated at the Pwn2Own Ireland 2025 hacking competition. The vulnerability stems from an unchecked buffer input, which allows for arbitrary code execution. Successful exploitation of CVE-2025-12686 could allow an attacker to bypass the firewall and access personally identifiable information (PII) and trade secrets. Furthermore, the attacker could use the NAS's trusted internal IP address to move laterally toward the Domain Controller (DC) or virtual desktop infrastructure (VDI). Synology has released a patch to address this vulnerability.
