The Month Of Twitter Bugs has begun with the publication of a flaw in a 
URL shortening service often used in conjunction with the micro-blogging 
service.

Four cross-site scripting (XSS) vulnerabilities in the bit.ly 
URL-shrinking service were published on Wednesday. TweetDeck, one of the 
most popular Twitter clients, integrates bit.ly, making the flaws much 
more risky than might otherwise be the case. Fortunately, three of the 
fours bugs were fixed before an alert was published. The last flaw was 
addressed hours after the release of a notice via Twitpwn, the home page 
of the Month Of Twitter Bugs project.

On Thursday, the Twitpwn project published details of a resolved 
cross-site scripting flaw in HootSuite toolbox.

The Month of Bugs series was inaugurated three years about with a four 
week period that offered a different browser bugs every day. Originally, 
the brainchild of HD Moore, of Metasploit fame, noted researcher Aviv 
Raff is applying the idea to Twitter and associated service during July. 
He notes that the idea might just have easily be applied to any other 
Web 2.0 service.
