*Vulnerability Type:* Path Traversal
https://owasp.org/www-community/attacks/Path_Traversal*Vendor of
Product:
*Advanced Comment System - ACS
*Version:* v1.0
*Attack Type:* Remote
*Impact:* A path traversal attack (also known as directory
traversal) aims
to access files and directories that are stored outside the web
root
folder. By manipulating variables that reference files with
“dot-dot-slash
(../)” sequences and its variations or by using absolute file
paths, it may
be possible to access arbitrary files and directories stored on
file system
including application source code or configuration and critical
system
files. It should be noted that access to files is limited by
system
operational access control (such as in the case of locked or in-use
files
on the Microsoft Windows operating system). This attack is also
known as
“dot-dot-slash”, “directory traversal”, “directory climbing”
and
“backtracking”.
