Hi there,

This is a security advisory for Netflow Analyzer customers using versions 123052 or earlier. We recommend that you upgrade to the latest version of Netflow Analyzer, 123057, to fix the security vulnerability described below.


Description: Netflow Analyzer contained a vulnerability through which it was possible to upload files using an unauthenticated servlet. This was identified and disclosed by Digital Defense, a provider of security risk assessment solutions. For details, please refer to the public disclosure published on January 30th.


Severity: Very high.


Affected users: Netflow Analyzer customers using version 123052 or earlier.


Background: Digital Defense responsibly disclosed the vulnerability to ManageEngine in November of 2017. Shortly afterwards, our security and development teams touched base with Digital Defense to gather more information. We accord the highest priority to fixing vulnerabilities, and this particular vulnerability was addressed on January 2nd with an update to Netflow Analyzer (123057). Customers using this version and above already have protection from the disclosed vulnerability.

Next step: Download the upgrade pack from https://www.manageengine.com/products/netflow/service-packs.html


and immediately upgrade to the latest version (123057). Please read the upgrade instructions carefully before beginning the upgrade. For assistance, write to netflowanalyzer-support@manageengine.com or call us toll-free at +1.888.720.9500.


Important note: As always, make a copy of the entire Netflow Analyzer installation folder before applying the upgrade and keep the copy in a separate location. If anything goes wrong during the upgrade, you'll have this copy as a backup, which will keep all your settings intact. If you're using a MS SQL server as a back-end database, back up the Netflow Analyzer database before upgrading. Once the upgrade is successfully completed, remember to delete the backup.


We offer our sincerest apologies for any inconvenience this may have caused.


Best regards,

ManageEngine Netflow Analyzer
