Some people advise dumping it for a different password manager, while other experts say using any password manager is better than using none and reusing the same old pathetic password on multiple sites. If you are sticking with LastPass, please make sure you have the most updated version of the software. This is not the first time security researchers, including Ormandy, have taken aim at LastPass. 3.3.2 is the most popular LastPass add-on for Firefox, but it was to be replaced by the add-on version 4.x in April. Our security is investigating and working on issuing a fix.”Ībout two weeks ago, LastPass said it planned to retire the LastPass 3.3.2 Firefox add-on due to Mozilla’s plans to move from its add-on API to WebExtensions by the end of 2017.

Full report will be on the way shortly.Ī few hours after that, LastPass tweeted, “We are aware of reports of a Firefox add-on vulnerability. I found another bug in LastPass 4.1.35 (unpatched), allows stealing passwords for any domain. Installing the extension afterwards still showed the same problem. He hoped LastPass had resolved the issue instead of just removing the DNS entry, or else DNS responses could be inserted during a man-in-the-middle attack. In my case, deleting all files from C:UsersuserAppDataLocalGoogleChromeUser DataDefaultdatabases and rebooting chrome did not resolve things. Below are some of the possible reasons for LastPass to stop working on your device. Ormandy didn’t reveal details until LastPass said the RCE vulnerability in the Chrome extension had been addressed. There could be several reasons why LastPass is not working on your device. Details were to be published on the company’s blog, but were not published at the time of writing this. LastPass first came up with a workaround, but a few hours later declared the security issue was fixed. Naturally, calc.exe will not appear on a Mac.” Nevertheless, in the bug report, Ormandy said LastPass initially told him that “they couldn't get my exploit to work, but I checked my Apache access logs and they were using a Mac. It doesn’t seem like rocket science to grasp that Windows Calculator will only run on Windows. If you are running a vulnerable LastPass browser extension version, then Ormandy’s proof-of-concept demonstration will run Windows Calculator.

If “Binary Component” is installed – it is on by default in Firefox and Internet Explorer – then Ormandy said, “This even allows arbitrary code execution.” In case you don’t know, remote code execution (RCE) is a critical vulnerability and as bad as a flaw gets you could think of it like the devil – unless of course you are a bad guy wanting to remotely control your target’s computer and then it would be your friend. His bug report explained that there are hundreds of internal privileged LastPass RPC commands, but LastPass users wouldn’t want bad actors accessing RPCs which would allow passwords to be copied. “There are a lot of RPCs, allowing complete control of the LastPass extension, including stealing passwords,” Ormandy wrote.
