CVE-2023-39680Network attack vector

Remote arbitrary code execution

Published Oct 20, 2023 · Updated Sep 12, 2024

Deserialization of untrusted data in Sollace Unicopia 1.1.1 and earlier allows remote attackers to execute arbitrary code. The public disclosure does not identify the deserialization method, data format, or input path that processes attacker-controlled data. The required user action and crafted-input delivery path remain undisclosed, while successful exploitation runs code in the receiving process.
