Dlink Dir-3040us A1 1.20b03a hotfix is vulnerable to Buffer Overflow. Any user having read/write access to ftp server can write directly to ram causing buffer overflow if file or files uploaded are greater than available ram. Ftp server allows change of directory to root which is one level up than root of usb flash directory. During upload ram is getting filled and causing system resource exhaustion (no free memory) which causes system to crash and reboot.

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.
