Vulnerability in Freebsd

CVE-2005-2359

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.

EPSS: 0.009 (56.2th percentile) — read the EPSS interpretation.
