    Hi all,

    Really quick query for you I'd imagine. I've started seeing the occasional cgi error appearing in my error log on the vps, such as the following:

    Code:
    [Sun Jan 17 13:25:19.808822 2016] [cgi:error] [pid 7648] [client 191.236.119.223:1129] AH01215: (13)Permission denied: exec of '/usr/local/apache/cgi-bin/test-cgi' failed: /usr/local/apache/cgi-bin/test-cgi

    Code:

    I don't have any cgi scripts and have disabled them as far as I know. The only user on the vps is for my employers website and is managed by me (so no external users). The error above looks as if someone is attempting to use a cgi script on the vps, but is failing due to the fact its not enabled.

    Is it something to worry about? Would someone have to have already gained access to the vps to be able to even attempt the above?

    Hello :)

    You can block the individual IP addresses in your firewall. I suggest installing a firewall management utility such as CSF if you have not already done so. The requests on their own are not harmful, but rather indicate an access attempt from a person or script that's likely checking for vulnerabilities.

    Thank you.

    It is likely someone scanning for the old shellshock exploit (which has been patched for some time) but you would need the apache access logs from around that same time to verify.
