AVEVA System Platform 2020 stores sensitive information in cleartext, which may allow access to an attacker or a low-privileged user.

The vulnerability, if exploited, could allow a malicious entity with access to the file system to achieve arbitrary code execution and privilege escalation by tricking AVEVA Edge to load an unsafe DLL.

AVEVA Software Platform Common Services (PCS) Portal versions 4.5.2, 4.5.1, 4.5.0, and 4.4.6 are vulnerable to DLL hijacking through an uncontrolled search path element, which may allow an attacker control to one or more locations in the search path.

This privilege escalation vulnerability, if exploited, cloud allow a local OS-authenticated user with standard privileges to escalate to System privilege on the machine where these products are installed, resulting in complete compromise of the target machine.

An exception is thrown from a function in AVEVA System Platform versions 2017 through 2020 R2 P01, but it is not caught, which may cause a denial-of-service condition.

AVEVA System Platform versions 2017 through 2020 R2 P01 does not verify, or incorrectly verifies, the cryptographic signature for data.

AVEVA System Platform versions 2017 through 2020 R2 P01 uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

AVEVA System Platform versions 2017 through 2020 R2 P01 does not properly verify that the source of data or communication is valid.

This external control vulnerability, if exploited, could allow a local OS-authenticated user with standard privileges to delete files with System privilege on the machine where these products are installed, resulting in denial of service.

Untrusted search path vulnerability in Schneider Electric Wonderware System Platform before 2014 R2 Patch 01 allows local users to gain privileges via a Trojan horse DLL in an unspecified directory.
