Karau admits that the Hack Day wasn't the best place to bring the issue up, but claims that – despite not placing in the competition, unsurprisingly – he has no regrets: “ In retrospect it probably wasn't the best forum to bring up the security defects, but it was the most convenient.”Ī spokesperson for Yahoo claims that “ problem has already been addressed in code, and fix is in the next release,” although offers no explanation for how e-mail software in this day and age could be set to plain-text authentication.Īny Zimbra users out there panicking about who's reading their e-mails, or don't you care who has access to your spam?

For users on a wireless network, it's even more of an issue: wireless systems work by broadcasting all data to all clients, making it trivial to eavesdrop a conversation and pick up the password. This post shares some great ideas for both end users and email admins.

#ZIMBRA DESKTOP EXPLOIT UPGRADE#
While the flaw requires a fairly unlikely attack – at some point between you and the server, an attacker would have to 'sniff' the traffic to capture the passwords – it is by no means impossible to exploit. Zimbra, an open-source email and collaboration platform, has released a security upgrade to fix a discovered Cross-Site Scripting (XSS) zero-day vulnerability. Check out our Best Practices for Personal Email Security, which includes a 14-step checklist, to learn easy tips and tricks to protect yourself from three of the most common and real threats: Also check out XMission’s blog Best Practices for Zimbra Email Security. In a post on his blog, Holden explains that the IMAP e-mail servers that Yahoo uses for its Yahoo Zimbra Desktop client don't support the Secure Sockets Layer encryption protocol, which means “ the password was being transmitted in plain text.” Unfortunately, Yahoo got rather more than it bargained for from Karau. If you use Yahoo's Zimbra client to check your e-mails, you might want to think about changing your passwords – a flaw in the program reveals your private information in plain text.Īccording to an article over on CNet, Canadian hacker Holden Karau discovered the flaw in Zimbra whilst participating in the Yahoo University Hack Day, a programme aimed at encouraging developers and hackers to play with Yahoo APIs and invent new applications.
