Fortinet advises that a recently discovered vulnerability has been found in the FortiReporter product . The Fortinet Engineering team has reviewed it and provided a fix for it.

Vulnerability description:

The vulnerability specifically exists within the Syslog daemon, syslogserver.exe, during the processing of long arguments passed through various commands on TCP port 10617. The following commands are known to be affected:

  • DELTAINTERVAL
  • LOGFOLDER

Fortinet's Analysis:

Using long argument strings with the above cases results in a classic buffer overflow.

Products affected:

All FortiReporter products running versions earlier than 4.5.3

Risk:

Solution:

Engineering has patched the syslogserver.exe daemon in version 4.5.3 to now check arguments so that buffer overflows can not occur. You may obtain the latest firmware from Fortinets web site at : FortiReporter
