An unquoted search path vulnerability exists in 'JustSystems JUST Online Update for J-License' bundled with multiple products for corporate users as in Ichitaro through Pro5 and others. Since the affected product starts another program with an unquoted file path, a malicious file may be executed with the privilege of the Windows service if it is placed in a certain path. Affected products are bundled with the following product series: Office and Office Integrated Software, ATOK, Hanako, JUST PDF, Shuriken, Homepage Builder, JUST School, JUST Smile Class, JUST Smile, JUST Frontier, JUST Jump, and Tri-De DetaProtect.
The product uses a search path that contains an unquoted element, in which the element contains whitespace or other separators. This can cause the product to access resources in a parent path.
