By using special elements such as \"..\" and \"\u002F\" separators, attackers can escape outside of the restricted location to access files or directories that are elsewhere on the system. One of the most common special elements is the \"..\u002F\" sequence, which in most modern operating systems is interpreted as the parent directory of the current location. This is referred to as relative path traversal. Path traversal also covers the use of absolute pathnames such as \"\u002Fusr\u002Flocal\u002Fbin\" to access unexpected files.
