Check Point recommends to always upgrade to the most recent version ([upgrade Security Gateway](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=downloads&product=435) / [upgrade Cluster](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=downloads&product=428) / [upgrade Security Management Server](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=downloads&product=184) / [upgrade Multi-Domain Security Management Server](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=downloads&product=166)).

If you wish not to upgrade, as a workaround, use Internet Explorer, or perform the following steps from the Expert mode on the affected machine:

**NOTE:** This changes does not survive reboot. For a permanent fix, install the hotfix.

1. Backup the `/web/htdocs2/login/login.js` file:  

   `[Expert@HostName:0]# cp /web/htdocs2/login/login.js /web/htdocs2/login/login.js.backup`  

2. Run this command:  

   `[Expert@HostName:0]# grep -q "form.el.dom.action" /web/htdocs2/login/login.js; if [ $? -eq 0 ]; then echo File is already modified, exiting.; else echo File backed up and modified. ; sed -i.bak '/form.isValid/s/$/\nform.el.dom.action=formAction;\n/' /web/htdocs2/login/login.js ; fi`

   By running the above command, the following modifications will be made in the `/web/htdocs2/login/login.js` file:

   Line 52 from:

   ` `

   `function submitLoginForm(){`  
   ` var form = Ext.getCmp( 'webui_login_form' ).getForm();`  
   ` if( form.isValid() ){`  
   ` form.submit();`  
   ` }`  
   `}`

   will be changed to :

   ` `

   `function submitLoginForm(){`  
   ` var form = Ext.getCmp( 'webui_login_form' ).getForm();`  
   ` if( form.isValid() ){`  
   ` form.el.dom.action=formAction;`  
   ` form.submit();`  
   ` }`  
   `}`
3. Reload the Gaia Portal login page.  
   **Note:** cprestart is not required. The next time the login page is loaded, it will work correctly.

4. If the Hotfix is not available for the version affected, then the file `/etc/rc3.d/S99local `can be amended to include the commands to modify` /web/htdocs2/login/login.js`. This script runs during the boot up process.   

   Example:  

   `# `  
   `# Fix SK121373 `  
   `# `  
   `grep -q "form.el.dom.action" /web/htdocs2/login/login.js; if [ $? -eq 0 ]; then echo File is already modified, exiting.; else echo File backed up and modified. ; sed -i.bak '/form.isValid/s/$/\nform.el.dom.action=formAction;\n/' /web/htdocs2/login/login.js ; fi`  
   `# `  
   ``echo -e "Fix SK121373 applied at `date` from S99local" >> /var/log/messages``
