"According to the versions of the php packages installed, the EulerOS installation on the remote host is affected by the
following vulnerabilities :
- In PHP versions 7.3.x below 7.3.33, 7.4.x below 7.4.26 and 8.0.x below 8.0.13, certain XML parsing
functions, like simplexml_load_file(), URL-decode the filename passed to them. If that filename contains
URL-encoded NUL character, this may cause the function to interpret this as the end of the filename, thus
interpreting the filename differently from what the user intended, which may lead it to reading a
different file than intended. (CVE-2021-21707)

advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
