Issue/Introduction

 

We're running a Web Agent and when this one handle the following URL,
it doesn't urlencode the SMTOKEN value :

    https://myserver.mydomain.com/changepassword.do?method=changepassword&status=reset&SMENC=UTF-8&USERNAME=myusername&SMENC=UTF-8&SMTOKEN={RC2}451v5sINtfZ9NqThbVcBwAntT5iHEjLU6kkNPnmBr66Z6JXHdfSvqtuFvuABJ+i&USERNAME=myusername&SMAUTHREASON=24&SMAGENTNAME=ds5dsfssdc9jGVoxl9cCk4YsWXdgLtaJWt4dtcV7Vcl6dpTI4YK2P9JqIftcC09&TARGET=$SM$https%3A%2F%2Fmyserver.mydomain.com%2Flogin.do

  Value : SMTOKEN={RC2}451v5sINtfZ9NqThbVcBwAntT5iHEjLU6kkNPnmBr66Z6JXHdfSvqtuFvuABJ+i

This happens on old Web Agent 12SP3CR12 as per more recent Web Agent
12.52SP1CR05, the value is correctly urlencoded :

    https://myotherserver.mydomain.com/changepassword.do?method=changepassword&status=reset&SMENC=UTF-8&USERNAME=myuser&SMENC=UTF-8&SMTOKEN=$SM$%7bRC2%7dcdZWTT%3dsaadmuZITZTh4VJy4bFjDczVwPykGwo8sc5dsDsdsR688OYCo6mLxtMKhsMj&USERNAME=myuser&SMAUTHREASON=24&SMAGENTNAME=$SM$dsadasd44ds2XSooudm2z3f4t3L6vAOEBLYsRhJX%2bGVC%2ftX9rTaimeJqFGiI33B&TARGET=$SM$https%3A%2F%2Fmyotherserver.mydomain.com%2Flogin.do

    Value : SMTOKEN=$SM$%7bRC2%7dcdZWTT%3dsaadmuZITZTh4VJy4bFjDczVwPykGwo8sc5dsDsdsR688OYCo6mLxtMKhsMj

Why the 12.52SP1CR05 version doesn't show the problem ?

 

Cause

 

At first glance, we note that the value causing problem doesn't have
the -SM- tag, which will be responsible to handle the {} characters as
per the following KD and needed to respect RFC 3986 :

According to the following KD, the tag is added from Web Agent
12.52SP1CR05 only :

  Issue with force change password feature

    We've seen that the -SM- tag in the SMTOKEN value causes the IM server
    not to be able to handle the request.
    The addition of the -SM- part it the SMTOKEN in Web Agent 12.52SP1 is
    about to be compliant on the security aspect with RFC 3986 around the
    presence of {} character in URLs.

    To solve this issue and make the IM server to be compliant to that,
    you need to upgrade the IM server to version 14.3 to handle this.
