workarounds:
The vulnerabilities are partially remediated in FOXMAN-UN R16A or UNEM R16A, the full remediation will be done in the upcoming release (planned).
For immediate recommended mitigation actions if using FOXMAN-UN R16A or UNEM R16A,
please refer to the
Database contains credentials with weak encryption
clause of section Mitigation Factors/Workarounds
in the respective products' advisory.
For immediate recommended mitigation actions if using FOXMAN-UN R15B or UNEM R15B and earlier, please refer to the multiple clauses of section Mitigation Factors/Workarounds in the advisory
*  Secure the NMS CLIENT/SERVER communication.
*  Embedded FOXCST with RADIUS authentication should be avoided.
*  Database contains credentials with weak encryption.
