  • Aug 21, 2024Flamix: Bitrix24 and Contact Form 7 integrations: Full Path DisclosureCVE-2024-6568 · WordPress plugins & themes · reported by WordfenceMedium 5.3

    The Flamix: Bitrix24 and Contact Form 7 integrations plugin for WordPress is vulnerable to Full Path Disclosure in all versions up to, and including, 3.1.0. This is due the plugin utilizing mobiledetect without preventing direct access to the files. This makes it possible for unauthenticated attackers to retrieve the full path of the web application, which can be used to aid other attacks. The information displayed is not useful on its own, and requires another vulnerability to be present for damage to an affected website.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
