Novell eDirectory Host Environment Service (dhost.exe) HTTP Connection Header DoS

high Nessus Plugin ID 31863
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote directory service is affected by a denial of service issue.


The remote host is running eDirectory, a directory service software from Novell.

The installed version of eDirectory is affected by a denial of service issue. By sending an HTTP request with a specially crafted 'Connection' header to the server, an unauthenticated attacker may be able to trigger a denial of service condition causing dhost.exe to consume 100% of the CPU and crash the system.


Upgrade to eDirectory 8.8.2/8.7.3 SP10 or later.
