The control panel for Positive Software H-Sphere before 2.5.0 RC3 creates log files in a user's directory with insecure permissions, which allows local users to append log data to arbitrary files via a symlink attack. NOTE: The provenance of this information is unknown; the details are obtained solely from third party information.

Cross-site scripting (XSS) vulnerability in the Hosting Control Panel (psoft.hsphere.CP) in Positive Software H-Sphere 2.4.3 Patch 8 and earlier allows remote attackers to inject arbitrary web script or HTML via the login parameter in a login action.

H-Sphere Winbox 2.4.2 and 2.4.3 RC1 stores sensitive information such as username and password in plaintext in world-readable log files, which allows local users to gain privileges.
