According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.33. It is, therefore, affected by multiple vulnerabilities:
An out of bounds write vulnerability exists in mod_authnz_ldap with AuthLDAPCharsetConfig enabled. An unauthenticated, remote attacker can exploit this, via the Accept-Language header value, to cause the application to stop responding. (CVE-2017-15710)
An arbitrary file upload vulnerability exists in the FilesMatch component where a malicious filename can be crafted to match the expression check for a newline character. An unauthenticated, remote attacker can exploit this, via newline character, to upload arbitrary files on the remote host subject to the privileges of the user. (CVE-2017-15715)
A session management vulnerability exists in the mod_session component due to SessionEnv being enabled and forwarding it’s session data to the CGI Application. An unauthenticated, remote attacker can exploit this, via tampering the HTTP_SESSION and using a session header, to influence content. (CVE-2018-1283)
An out of bounds access vulnerability exists when the size limit is reached. An unauthenticated, remote attacker can exploit this, to cause the Apache HTTP Server to crash. (CVE-2018-1301)
A write after free vulnerability exists in HTTP/2 stream due to a NULL pointer being written to an area of freed memory. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2018-1302)
An out of bounds read vulnerability exists in mod_cache_socache.
An unauthenticated, remote attacker can exploit this, via a specially crafted HTTP request header to cause the application to stop responding. (CVE-2018-1303)
A weak digest vulnerability exists in the HTTP digest authentication challenge. An unauthenticated, remote attacker can exploit this in a cluster of servers configured to use a common digest authentication, to replay HTTP requests across servers without being detected. (CVE-2018-1312)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
