CVE-2013-10047 is a critical-severity vulnerability rated 9.3/10 on the CVSS scale. An unrestricted file upload vulnerability exists in MiniWeb HTTP Server <= Build 300 that allows unauthenticated remote attackers to upload arbitrary files to the server’s filesystem. By abusing the upload handler and crafting a traversal path, an attacker can place a malicious .exe in system32, followed by a .mof file in the WMI directory. EPSS estimates a 0.99% chance of exploitation in the next 30 days.

Description

An unrestricted file upload vulnerability exists in MiniWeb HTTP Server <= Build 300 that allows unauthenticated remote attackers to upload arbitrary files to the server’s filesystem. By abusing the upload handler and crafting a traversal path, an attacker can place a malicious .exe in system32, followed by a .mof file in the WMI directory. This triggers execution of the payload with SYSTEM privileges via the Windows Management Instrumentation service. The exploit is only viable on Windows versions prior to Vista.
