CVE-2016-2058

Multiple cross-site scripting (XSS) vulnerabilities in Xymon 4.1.x, 4.2.x, and 4.3.x before 4.3.25 allow (1) remote Xymon clients to inject arbitrary web script or HTML via a status-message, which is not properly handled in the "detailed status" page, or (2) remote authenticated users to inject arbitrary web script or HTML via an acknowledgement message, which is not properly handled in the "status" page.

Updated xymon packages fix security vulnerabilities:

The incorrect handling of user-supplied input in the "config" command can trigger a stack-based buffer overflow, resulting in denial of service (via application crash) or remote code execution (CVE-2016-2054).

The incorrect handling of user-supplied input in the "config" command can lead to an information leak by serving sensitive configuration files to a remote user (CVE-2016-2055).

The commands handling password management do not properly validate user-supplied input, and are thus vulnerable to shell command injection by a remote user (CVE-2016-2056).

Incorrect permissions on an internal queuing system allow a user with a local account on the xymon master server to bypass all network-based access control lists, and thus inject messages directly into xymon (CVE-2016-2057).

Incorrect escaping of user-supplied input in status webpages can be used to trigger reflected cross-site scripting attacks (CVE-2016-2058).

Note that to effectively fix CVE-2016-2055, the /etc/xymon/xymonpasswd configuration file should be owned by user and group apache with 640 permissions.
