CVE-2005-2359
FreeBSD 5.3-5.4 - IPsec AES-XCBC-MAC Authentication Bypass via Constant Key
Title source: llmDescription
The AES-XCBC-MAC algorithm in IPsec in FreeBSD 5.3 and 5.4, when used for authentication without other encryption, uses a constant key instead of the one that was assigned by the system administrator, which can allow remote attackers to spoof packets to establish an IPsec session.
