EBay disabled a password function on its site Tuesday to close a "very serious" security hole that could allow hackers access to users' accounts, a spokesman said. EBay disabled the "Change Your Password" function in an effort to close the vulnerability, eBay spokesman Kevin Pursglove said Tuesday. That feature will remain disabled until eBay can put a fix in place, he said. "We don't see (the vulnerability) existing in other features," and no customers have complained, Pursglove said. "From what we can tell right now, we have not seen anybody's account compromised in any way." Greg Shipley, chief technology officer of security consulting firm Neohapsis, blamed the problem on a "design failure" in eBay's authentication system. "It's just a bad design. It's kind of disappointing coming from a company the size of eBay," Shipley said. The vulnerability, discovered by a Canadian security expert and brought to eBay's attention late last week, would allow a person who has the user ID of an account to go in through eBay's "Change Your Password" feature, change a user's password and gain access to the account. Pursglove said people who potentially exploited the vulnerability would not have been able to see credit card numbers. "What they can see is the credit card transaction history of a user," Pursglove said, calling the problem "very serious." The credit card numbers, he said, are behind a separate firewall. While eBay has disabled access to that security hole, the company is still working on a fix for an earlier problem involving so-called dictionary attacks. These attacks utilize a bot, or an automated program, to find passwords for known eBay user IDs by combing though a list of common passwords and a dictionary of words. EBay has said that the number of accounts compromised by dictionary attacks has been no more than the "low triple digits." The company has also said that less than one one-hundredth of 1 percent of its listings end in confirmed cases of fraud. "We're working on it right now," Pursglove said, adding that changes to the login procedure would be in place in four to six weeks. "We think it will make it harder for these (attacks) to work." Security experts have criticised the company's log-in system, saying that because it generally transmits passwords and account information in plain text, it is vulnerable to "packet sniffers," programs that can monitor the transmission of data between computers. EBay has also repeatedly warned members in recent months about another, more low-tech scam: fraudulent e-mail messages that purport to come from the company but link to bogus Web sites that ask for their passwords or other account information.

Talkback

In your letter you say that you have closed the Change your Password Option,I am one of the poor unfortunate account holders that had their account hacked into.Since being taken off ebay I have tried relentlessly to get back on asking for assistance in regaining my account status.I.E. I have asked to be re-enstated as I changed my passowrd just after I removed 43 items from my site that were not mine and then asked ebay to remove the fee they had creditied to my account.(they removed the fee)but all I have had is automated emails telling me of the seriousness of this matter but no email to my addressto tell me how to complete the password change.
This is not the first time this has happened to my account either! Last august I had an item placed on my account which took 14 days to sort out before they let me back on. Why is it then that the ebay account holder is treated like a criminal rather than a vistim?
An ebay spoksman was to have said to the daily star newspaper today that they are working closely with the trading standards and the police to stop this fraudulant activity.What happens to the account holder in the mean time,are they kept hanging on a thread with no hope of re-gaining their site?
I have left many a message with regards to re-enstatement only to have an automated email sent back,very frustrating and stressful.Am I now lead to believe that there is definately no hope of getting back on ebay because of the "Password Change"being suspended????
You don,t understand the anguish it causes till it happens to you !!!!!!!!!!!!
