CVE-2010-4648

First published: Fri Jan 07 2011(Updated: )

Enable the port when disabling countermeasures, and disable it on enabling countermeasures. This bug causes the response of the system to certain attacks to be ineffective. It also prevents wpa_supplicant from getting scan results, as wpa_supplicant disables countermeasures on startup - preventing the hardware from scanning. wpa_supplicant works with ap_mode=2 despite this bug because the commit handler re-enables the port. The log tends to look like: State: DISCONNECTED -&gt; SCANNING Starting AP scan for wildcard SSID Scan requested (ret=0) - scan timeout 5 seconds EAPOL: disable timer tick EAPOL: Supplicant port status: Unauthorized Scan timeout - try to get results Failed to get scan results Failed to get scan results - try scanning again Setting scan request: 1 sec 0 usec Starting AP scan for wildcard SSID Scan requested (ret=-1) - scan timeout 5 seconds Failed to initiate AP scan.
