Apache 2.4.x < 2.4.33 Multiple Vulnerabilities
critical Nessus Plugin ID 122060

Synopsis
The remote web server is affected by multiple vulnerabilities.Description
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.
