OpenSSL has internal defaults for a directory tree where it can find a configuration file as well as certificates used for verification in TLS. This directory is most commonly referred to as OPENSSLDIR, and is configurable with the –prefix / –openssldir configuration options. For OpenSSL versions 1.1.0 and 1.1.1, the mingw configuration targets assume that resulting programs and libraries are installed in a Unix-like environment and the default prefix for program installation as well as for OPENSSLDIR should be ‘/usr/local’. However, mingw programs are Windows programs, and as such, find themselves looking at sub-directories of ‘C:/usr/local’, which may be world writable, which enables untrusted users to modify OpenSSL’s default configuration, insert CA certificates, modify (or even replace) existing engine modules, etc. For OpenSSL 1.0.2, ‘/usr/local/ssl’ is used as default for OPENSSLDIR on all Unix and Windows targets, including Visual C builds. However, some build instructions for the diverse Windows targets on 1.0.2 encourage you to specify your own –prefix. OpenSSL versions 1.1.1, 1.1.0 and 1.0.2 are affected by this issue. Due to the limited scope of affected deployments this has been assessed as low severity and therefore we are not creating new releases at this time. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL 1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s).
CWE-427
CVE-2019-14684
A DLL hijacking vulnerability exists in Trend Micro Password Manager 5.0 in which, if exploited, would allow an attacker to load an arbitrary unsigned DLL into the signed service’s process. This process is very similar, yet not identical to CVE-2019-14687.
CVE-2019-14686
A DLL hijacking vulnerability exists in the Trend Micro Security’s 2019 consumer family of products (v15) Folder Shield component and the standalone Trend Micro Ransom Buster (1.0) tool in which, if exploited, would allow an attacker to load a malicious DLL, leading to elevated privileges.

CVE-2019-14688
Trend Micro has repackaged installers for several Trend Micro products that were found to utilize a version of an install package that had a DLL hijack vulnerability that could be exploited during a new product installation. The vulnerability was found to ONLY be exploitable during an initial product installation by an authorized user. The attacker must convince the target to download malicious DLL locally which must be present when the installer is run.
CVE-2019-14600
Uncontrolled search path element in the installer for Intel(R) SNMP Subagent Stand-Alone for Windows* may allow an authenticated user to potentially enable escalation of privilege via local access.
