Description
A vulnerability was detected in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 1.0.013.001/1.0.04.001/1.0.04.002/1.1.05.003/1.2.07.001. This vulnerability affects the function addStaProfile of the file /goform/addStaProfile. Performing manipulation of the argument profile_name/Ssid/wep_key_1/wep_key_2/wep_key_3/wep_key_4/wep_key_length/wep_default_key/cipher/passphrase results in stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
