GroupWise < 7.0.0 SP2 WebAccess GWINTER.exe Base64 Decoding Overflow

medium Nessus Network Monitor Plugin ID 3971
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 host is vulnerable to a buffer overflow.


The remote host is running a version of GroupWise WebAccess from Novell that fails to sanitize HTTP authentication requests. An overly long request will generate an overflow on the remote WebAccess server. An attacker exploiting this flaw would only need to be able to connect to the service and send an HTTP basic authentication request. Successful exploitation would result in the attacker executing arbitrary code.


Upgrade to version 7.0.0 SP2 or higher.
