According to its banner, the version of PHP running on the remote web server is 7.3.x prior to 7.3.6.
It is, therefore, affected by the following vulnerabilities:
An uninitialized vulnerability exists in gdImageCreateFromXbm due to sscanf method not being able to read a hex value. An attacker may be able exploit this issue, to cause the disclose of sensitive information. (CVE-2019-11038)
An out of bounds read vulnerability exists in iconv.c:_php_iconv_mime_decode() due to integer overflow.
An attacker may be able exploit this issue, to cause the disclose of sensitive information. (CVE-2019-11039)
