can\ntrigger a stack-based buffer overflow, resulting in denial of service (via\napplication crash) or remote code execution (CVE-2016-2054).\n\nThe incorrect handling of user-supplied input in the \"config\" command can\nlead to an information leak by serving sensitive configuration files to a\nremote user (CVE-2016-2055).\n\nThe commands handling password management do not properly validate\nuser-supplied input, and are thus vulnerable to shell command injection by a\nremote user (CVE-2016-2056).\n\nIncorrect permissions on an internal queuing system allow a user with a local\naccount on the xymon master server to bypass all network-based access control\nlists, and thus inject messages directly into xymon (CVE-2016-2057).\n\nIncorrect escaping of user-supplied input in status webpages can be used to\ntrigger reflected cross-site scripting attacks (CVE-2016-2058).\n\nNote that to effectively fix CVE-2016-2055, the /etc/xymon/xymonpasswd\nconfiguration file should be owned by user and group apache with 640\npermissions.\n","status":"published","published":"2016-05-18T20:14:22Z","modified":"2026-04-16T06:22:54.265759658Z","updated_at":"2026-11-02T15:49:39.792687Z"}]}}
