WordPress iOS App Bug Leaked Secret Access Tokens to Third-Party Sites

WordPress iOS App Bug Leaked Secret Access Tokens to Third-Party Sites

April 03, 2019Swati Khandelwal
If you have a "private" blog with WordPress.com and are using its official iOS app to create or edit posts and pages, the secret authentication token for your admin account might have accidentally been leaked to third-party websites. WordPress has recently patched a severe vulnerability in its iOS application that apparently leaked secret authorization tokens for users whose blogs were using images hosted on third-party sites, a spokesperson for Automattic confirmed The Hacker News in an email. Discovered by the team of WordPress engineers, the vulnerability resided in the way WordPress iOS application was fetching images used by private blogs but hosted outside of WordPress.com, for example, Imgur or Flickr. That means, if an image were hosted on Imgur and then when the WordPress iOS app attempted to fetch the image, it would send along a WordPress.com authorization token to Imgur, leaving a copy of the token in the access logs of the Imgur's web server.

If for some reason your WordPress-based website has not yet been automatically updated to the latest version 5.1.1, it's highly recommended to immediately upgrade it before hackers could take advantage of a newly disclosed vulnerability to hack your website. Simon Scannell, a researcher at RIPS Technologies GmbH, who previously reported multiple critical vulnerabilities in WordPress, has once again discovered a new flaw in the content management software (CMS) that could potentially lead to remote code execution attacks. The flaw stems from a cross-site request forgery (CSRF) issue in the Wordpress' comment section, one of its core components that comes enabled by default and affects all WordPress installations prior to version 5.1.1. Unlike most of the previous attacks documented against WordPress, this new exploit allows even an "unauthenticated, remote attacker" to compromise and gain remote code execution on the vulnerable WordPress websites.

WordPress, the most popular CMS in the world, is vulnerable to a logical vulnerability that could allow a remote attacker to reset targeted users’ password under certain circumstances. The vulnerability (CVE-2017-8295) becomes even more dangerous after knowing that it affects all versions of WordPress — including the latest 4.7.4 version. The WordPress flaw was discovered by Polish security researcher Dawid Golunski of Legal Hackers last year in July and reported it to the WordPress security team, who decided to ignore this issue, leaving millions of websites vulnerable. "This issue has been reported to WordPress security team multiple times with the first report sent back in July 2016. It was reported both directly via security contact email, as well as via HackerOne website," Golunski wrote in an advisory published today. "As there has been no progress, in this case, this advisory is finally released to the public without an official patch." Golunski

WordPress Security: Brute Force Amplification Attack Targeting Thousand of Blogs

October 09, 2015Swati Khandelwal
Most of the times, we have reported about WordPress vulnerabilities involving vulnerable plugins, but this time security researchers have discovered Brute Force Amplification attacks on the most popular CMS (content management system) platform. Researchers from security firm Sucuri have found a way to perform Brute Force amplification attacks against WordPress' built-in XML-RPC feature to crack down administrator credentials. XML-RPC is one of the simplest protocols for securely exchanging data between computers across the Internet. It uses the system.multicall method that allows an application to execute multiple commands within one HTTP request. A number of CMS including WordPress and Drupal support XML-RPC. But… The same method has been abused to amplify their Brute Force attacks many times over by attempting hundreds of passwords within just one HTTP request, without been detected. Amplified Brute-Force Attacks This means instead of trying tho
