According to the versions of the net-snmp packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
Net-SNMP through 5.7.3 has Improper Privilege Management because SNMP WRITE access to the EXTEND MIB provides the ability to run arbitrary commands as root.(CVE-2020-15862)
Net-SNMP through 5.7.3 allows Escalation of Privileges because of UNIX symbolic link (symlink) following.(CVE-2020-15861)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
