CVE-2021-33728 (GCVE-0-2021-33728)

Vulnerability from cvelistv5 – Published: 2021-10-12 09:49 – Updated: 2024-08-03 23:58

Summary

A vulnerability has been identified in SINEC NMS (All versions < V1.0 SP2 Update 1). The affected system allows to upload JSON objects that are deserialized to JAVA objects. Due to insecure deserialization of user-supplied content by the affected software, a privileged attacker could exploit this vulnerability by sending a crafted serialized Java object. An exploit could allow the attacker to execute arbitrary code on the device with root privileges.
