Descriptions

The Intersil isl3893 extensions for Boa 0.93.15, as used on the FreeLan RO80211G-AP and other devices, do not prevent stack writes from entering memory locations used for string constants, which allows remote attackers to change the admin password stored in memory via a long username in an HTTP Basic Authentication request.

The Intersil extension in the Boa HTTP Server 0.93.x - 0.94.11 allows basic authentication bypass when the user string is greater than 127 bytes long. The long string causes the password to be overwritten in memory, which enables the attacker to reset the password. In addition, the malicious attempt also may cause a denial-of-service condition. Please note that you must set the request URI to the directory that requires basic authentication in order to work properly.
