SOLVED CPANEL-40481 - Issue using whmapi1 CLI to reset password

Operating System & Version
CloudLinux release 7.9
cPanel & WHM Version
102.0 (build 11)


Nov 10, 2010
When using WHM API1 via CLI , if the user's password begins with @ , your system throws up the following error.

[[email protected] ~]# whmapi1 --output=jsonpretty passwd user='user' password="@samudra123"
Cpanel::Exception::IO::FileNotFound/(XID zjsfdw) The system cannot find a file named “samudra123”.

bin::apitool::run(__CPANEL_HIDDEN__, __CPANEL_HIDDEN__, __CPANEL_HIDDEN__, __CPANEL_HIDDEN__) called at bin/ line 40

Apart from not being able to set the password that begins from @ , though it may seems exaggerated, but a well a crafted requested maybe able to exploit other aspects which maybe beyond this functionality

I have not tested it with other password sequences. I believe the input parameters should be character proof of at-least all ASCII characters.

Server's cPanel version is 102.0 (build 11)

I did hear back from our developers that this is actually intended behavior with the API system. "@" is one of the special characters in URI encoding, which is outlined here:

so anything starting with @ for a URI value is interpreted as a file name. Here are some more details from the whmapi help file:

[[email protected] /]# whmapi1 --help

Utility to execute WHM API calls

    whmapi1 [options] [function] [uri-key=uri-value] [uri-key=uri-value] ....

    Additional documentation is available at

    IMPORTANT: “uri-key” and “uri-value” represent URI-escaped strings.

    If “uri-value” begins with “@”, it is treated as a file name from which to
    read (without URI-escaping).
