18.5.2 - Can't execute scripts anymore

wget was removed on the appliance. Does your script use wget? 

"curl" is blocked too, but actually, I don't think curl or wget are blocked, as I can wget or curl down the original file fine from the command line, it's just when I run the script I get permission denied, even if I remove the #!/bin/sh first line.

So looks like calling an executable file in any way is blocked, is there a work around? Even if I remove the .sh extension, it's still permission denied 

You need to give execute permission with chmod +x ns_speedtest_v4.sh

Example:

XG115w_XN03_SFOS 19.0.0 EAP1-Build244# vim test.sh
XG115w_XN03_SFOS 19.0.0 EAP1-Build244# ./test.sh
/bin/sh: ./test.sh: Permission denied
XG115w_XN03_SFOS 19.0.0 EAP1-Build244# chmod +x test.sh
XG115w_XN03_SFOS 19.0.0 EAP1-Build244# ./test.sh
Hello
XG115w_XN03_SFOS 19.0.0 EAP1-Build244#

sorry i'd left that bit out of screenshot, same issue. Maybe it works on v19, do you have any 18.5.2's to try:

Could be additional enhancements to protect the system itself. V19.0 EAP1 is not on the same stage of release cycle like MR2. 

The question remains, why would anybody execute scripts? 

Can you use "cat /proc/mounts" to see if /tmp is mounted with noexec?

If it is, you can remount it with exec permissions.

EDIT: Also, I don't remember if this still works, but if you cat and pipe to sh - It should execute the script. (This should bypass filesystems that are mounted with noexec.)

Example: "cat test.sh | sh"

thank you, you've been very helpful. I'm back in business. 

Just had the same hiccup, for exactly the same reason, thanks Prism!

For those wondering, it's as simple as;

mount -o remount,exec /tmp
