Wordpress Cookie Authentication VulnerabilityWordpress Cookie Authentication VulnerabilityPosted Nov 20, 2007 6:41 UTC (Tue) by lutchann (subscriber, #8872)In reply to: Wordpress Cookie Authentication Vulnerability by Ross Parent article: Wordpress Cookie Authentication Vulnerability
That's true of pretty much any authentication system, except those based on asymmetric cryptography. Wordpress is far from unusual in storing password equivalents on disk. So unless Wordpress somehow encouraged making the user table accessible to attackers, I still don't see why this is a big deal.

There are ones you can download for free and ones you can pay for. Just going out to pirate bay and doing a quick search I found downloads for MD5, SHA1, and NT Lan manager tables.
