CVE-2021-22674 is a vulnerability in Advantech Webaccessscada
Published on August 10, 2021
The affected product is vulnerable to a relative path traversal condition, which may allow an attacker access to unauthorized files and directories on the WebAccess/SCADA (WebAccess/SCADA versions prior to 8.4.5, WebAccess/SCADA versions prior to 9.0.1).
Weakness Type
Relative Path Traversal
The software uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. This allows attackers to traverse the file system to access files or directories that are outside of the restricted directory.
