An elevation of privilege vulnerability exists when Windows improperly handles hard links. An attacker who successfully exploited this vulnerability could overwrite a targeted file leading to an elevated status. To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system. The security update addresses the vulnerability by correcting how Windows handles hard links.

An elevation of privilege vulnerability exists when the Windows Update Stack fails to properly handle objects in memory, aka 'Windows Update Stack Elevation of Privilege Vulnerability'.

An issue was discovered in Veritas InfoScale 7.x through 7.4.2 on Windows, Storage Foundation through 6.1 on Windows, Storage Foundation HA through 6.1 on Windows, and InfoScale Operations Manager (aka VIOM) Windows Management Server 7.x through 7.4.2. On start-up, it loads the OpenSSL library from \usr\local\ssl. This library attempts to load the \usr\local\ssl\openssl.cnf configuration file, which may not exist. On Windows systems, this path could translate to <drive>:\usr\local\ssl\openssl.cnf, where <drive> could be the default Windows installation drive such as C:\ or the drive where a Veritas product is installed. By default, on Windows systems, users can create directories under any top-level directory. A low privileged user can create a <drive>:\usr\local\ssl\openssl.cnf configuration file to load a malicious OpenSSL engine, resulting in arbitrary code execution as SYSTEM when the service starts. This gives the attacker administrator access on the system, allowing the attacker (by default) to access all data, access all installed applications, etc.

An issue was discovered in Veritas Enterprise Vault through 14.0. On start-up, it loads the OpenSSL library. The OpenSSL library then attempts to load the openssl.cnf configuration file (which does not exist) at the following locations in both the System drive (typically C:\) and the product's installation drive (typically not C:\): \Isode\etc\ssl\openssl.cnf (on SMTP Server) or \user\ssl\openssl.cnf (on other affected components). By default, on Windows systems, users can create directories under C:\. A low privileged user can create a openssl.cnf configuration file to load a malicious OpenSSL engine, resulting in arbitrary code execution as SYSTEM when the service starts. This gives the attacker administrator access on the system, allowing the attacker (by default) to access all data, access all installed applications, etc. This vulnerability only affects a server with MTP Server, SMTP Archiving IMAP Server, IMAP Archiving, Vault Cloud Adapter, NetApp File server, or File System Archiving for NetApp as File Server.
