With different paths (e.g. /export/home/xymon/cgi-secure/...) on Solaris 11
(SPARC), I'm seeing the criticaleditor.sh issue too; nothing of consequence
differs from the existing and the newly supplied xymon-apache.conf, so
that's not it.

I'm all green/clear right now, so I don't have anything to acknowledge and
try that, I guess. :-)

Aside from an rcsid[] line, I don't see any difference in cgiwrap.c or
criticaleditor.c between 4.3.25 and 4.3.26; going back to 4.3.24, there are
definitely differences.

Just for the heck of it, I compiled 4.3.24, moved over
server/bin/criticaleditor.cgi to save it under a different name, and
dropped in the 4.3.24 version of it.  The page then came up without the
redirect problem!  I did _not_ attempt editing anything, just in case the
stored data format might have been changed/upgraded.  Note: I didn't even
replace cgiwrap or the link to it with the old one, just the actual
criticaleditor.cgi binary.

So something between 4.3.24 and 4.3.26 broke it - probably something in
criticaleditor.c.

Everything is working except the criticaleditor.sh link under
administrator, which gives me the following errors in the logs (masked my
ips):

[error] [client Y.Y.Y.Y] Request exceeded the limit of 10 internal
redirects due to probable configuration error. Use 'LimitInternalRecursion'
to increase the limit if necessary. Use 'LogLevel debug' to get a
backtrace., referer: http://X.X.X.X/xymon/xymon.html

The features that are currently using the same xymonpasswd file do work
properly:
enadis.sh
acknowledge.sh
I can add ackinfo.sh to the list of misbehaving CGI scripts:

When I view e.g.
https://xymon
.<domain>/xymon-cgi/svcstatus.sh?HOST=<somehost>&SERVICE=<someservice>&NKPRIO=1&NKTTGROUP=&NKTTEXTRA=
and fill out the acknowledge form on top, it does a POST request to
https://xymon.<domain>/xymon-seccgi/ackinfo.sh, but since recently
this returns a "404 Not Found", interestingly with the text "The
requested URL /xymon-seccgi/criticalview.sh was not found on this
server." (i.e. criticalview.sh instead of ackinfo.sh).

In the apache error log, this causes lines like this one:

[Thu Mar 03 14:16:16.673425 2016] [cgid:error] [pid 2311:tid
140260545623808] [client <ip>:52929] AH01264: script not found or unable to
stat: /usr/lib/xymon/cgi-secure/criticalview.sh, referer: https://xymon
.<domain>/xymon-cgi/svcstatus.sh?HOST=<somehost>&SERVICE=<someservice>&NKPRIO=1&NKTTGROUP=&NKTTEXTRA=

/usr/lib/xymon/cgi-secure/criticalview.sh indeed does not exists, but
/usr/lib/xymon/cgi-secure/ackinfo.sh does exist.

(Regarding the paths: I'm using the official Debian packages as this
is my server to test them.)

                Kind regards, Axel Beckert
