cURL 7.11.1 to 7.49.0 DLL Hijacking Arbitrary Code Execution

High

Synopsis

The host is using a version of cURL which is vulnerable to a DLL Hijacking.

Description

cURL / libcurl contains a flaw that is triggered when loading certain dynamic-link libraries incl. security.dll, secur32.dll, and ws2_32.dll. The program uses an insecure path to look for specific files or libraries that includes the current working directory, which may not be trusted or under user control. By placing a specially crafted library in the path and tricking a user into opening a FILETYPE file e.g. located on a remote WebDAV share, a context-dependent attacker can inject and execute arbitrary code with the privilege of the user running the program. Technical Information: Note: Library vulnerability. This code is used in a wide variety of software and the issue may manifest in a number of different ways. Depending on the implementation, it will vary if this vulnerability requires local access, or if it may be exploited remotely.

This issue only affects the Windows platform.
