In Xymon through 4.3.28, a buffer overflow vulnerability exists in the csvinfo CGI script. The overflow may be exploited by sending a crafted GET request that triggers an sprintf of the srcdb parameter.
In Xymon through 4.3.28, an XSS vulnerability exists in the csvinfo CGI script due to insufficient filtering of the db parameter.
In Xymon through 4.3.28, a buffer overflow vulnerability exists in history.c.
In Xymon through 4.3.28, a buffer overflow vulnerability exists in reportlog.c.
In Xymon through 4.3.28, a stack-based buffer overflow vulnerability exists in the alert acknowledgment CGI tool because of expansion in acknowledge.c.
In Xymon through 4.3.28, a buffer overflow exists in the status-log viewer CGI because of expansion in appfeed.c.
In Xymon through 4.3.28, a stack-based buffer overflow vulnerability exists in the history viewer component via a long hostname or service parameter to history.c.
In Xymon through 4.3.28, a stack-based buffer overflow exists in the status-log viewer component because of expansion in svcstatus.c.
Buffer overflow in xymon 4.3.17-1.
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...
lib/xymond_ipc.c in Xymon 4.1.x, 4.2.x, and 4.3.x before 4.3.25 use weak permissions (666) for an unspecified IPC message queue, which allows local users to inject arbitrary messages by writing to that queue.
Multiple buffer overflows in xymond/xymond.c in xymond in Xymon 4.1.x, 4.2.x, and 4.3.x before 4.3.25 allow remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a long filename, involving handling a "config" command.
xymond in Xymon 4.1.x, 4.2.x, and 4.3.x before 4.3.25 allow remote authenticated users to execute arbitrary commands via shell metacharacters in the adduser_name argument in (1) web/useradm.c or (2) web/chpasswd.c.
xymond/xymond.c in xymond in Xymon 4.1.x, 4.2.x, and 4.3.x before 4.3.25 allow remote attackers to read arbitrary files in the configuration directory via a "config" command.
Directory traversal vulnerability in the trend-data daemon (xymond_rrd) in Xymon 4.x before 4.3.12 allows remote attackers to delete arbitrary files via a .. (dot dot) in the host name in a "drophost" command.
Multiple cross-site scripting (XSS) vulnerabilities in the Web UI in Xymon before 4.3.1 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.
