Model: EAP225  
Hardware Version: V3
Firmware Version: 5.1.0

I have a site that uses several of the EAP225 in stand alone mode and the existing WPA2 passphrase contains < and >.

 

I'm trying out the Omada SDN controller software and it won't allow the existing passphrases (it calls them security keys) that contain the < and > characters. The error is: Request parameter contains XSS attack.

 

For example something like <bbbbbb> will fail.  I tried escaping them with &lt;bbbbbb&gt; but the Omada doesn't de-escape the string and the passphrase contains the &lt; and &gt; instead of the < or >. 

 

Any suggestions on ways to convince the the Omada software to allow these passphrases?

  @doublevision I don't know why you insist on using < or > characters, can't you change the password to other supported characters? Not only Omada, many websites, Apps, software platforms, etc., have their own character limit rules, and we can't ask them to meet the special setting needs of each user.

  @DIDADI I am currently using Omada software controller v5.12.9, which allows you to set a password with < or >  (WPA mode: WPA2-PSK/AES).If you are not using this version now, you can go to the official website to download and install firmware v5.12.9, or the updated beta firmware v5.13 by accessing Omada SDN Controller_V5.13 Beta (Released on Oct 8th, 2023) - Business Community (tp-link.com).

Thank you. That is very helpful. I look forward to seeing this fixed.

 

 I can't find 15.12.9 and 15.13.9 apparently doesn't connect to the cloud. I'm running the software controller which is only up to 15.12.7. The hardware controller is up to 15.12.9.

 

The current version 15.12.7 doesn't block all < or >. For example, it allows <aaaaaa> but blocks <bbbbbb>. I'm sure there is some logic in that...

Hi, maybe it doesn't support in controller mode, suggest you post a feature request with the error message screenshot here.

Just striving to develop myself while helping others.
