Stack-based buffer overflow in the Agranet-Emweb embedded management web server in Alcatel OmniSwitch OS7000, OS6600, OS6800, OS6850, and OS9000 Series devices with AoS 5.1 before 5.1.6.463.R02, 5.4 before 5.4.1.429.R01, 6.1.3 before 6.1.3.965.R01, 6.1.5 before 6.1.5.595.R01, and 6.3 before 6.3.1.966.R01 allows remote attackers to execute arbitrary code via a long Session cookie.

The management web interface in Alcatel-Lucent OmniSwitch 6450, 6250, 6850E, 9000E, 6400, and 6855 with firmware before 6.6.4.309.R01 and 6.6.5.x before 6.6.5.80.R02 generates weak session identifiers, which allows remote attackers to hijack arbitrary sessions via a brute force attack.

Cross-site request forgery (CSRF) vulnerability in sec/content/sec_asa_users_local_db_add.html in the management web interface in Alcatel-Lucent OmniSwitch 6450, 6250, 6850E, 9000E, 6400, 6855, 6900, 10K, and 6860 with firmware 6.4.5.R02, 6.4.6.R01, 6.6.4.R01, 6.6.5.R02, 7.3.2.R01, 7.3.3.R01, 7.3.4.R01, and 8.1.1.R01 allows remote attackers to hijack the authentication of administrators for requests that create users via a crafted request.
