Overview
System introduction
Oil field exploitation is field work featuring strong fluidity, large quantities of scattered points, and a long distance. In the process of oil field exploitation, out of management requirements, the oil and gas management center connects to the gathering and transportation control center, gas processing plant control center, gas transmission initial station, and field control layer through an industrial network. Therefore, the system needs a large number of wired and wireless networks for data transmission and remote system management. (mais…)
Jackson-databind Remote Code Execution Vulnerability (CVE-2020-8840) Threat Alert
março 9, 2020
Vulnerability Description
On February 19, National Vulnerability Database (NVD) disclosed a remote code execution vulnerability (CVE-2020-8840) that resulted from JNDI injection in jackson-databind and assigned a CVSS score of 9.8.
