V-214303
|
Medium |
Cookies exchanged between the Apache web server and the client, such as session cookies, must have cookie properties set to force the encryption of cookies. |
Cookies can be sent to a client using TLS/SSL to encrypt the cookies, but TLS/SSL is not used by every hosted application since the data being displayed does not require the encryption of the transmission. To safeguard against cookies, especially session cookies, being sent in plaintext, a cookie can be... |

V-214301
|
Medium |
The Apache web server cookies, such as session cookies, sent to the client using SSL/TLS must not be compressed. |
A cookie is used when a web server needs to share data with the client's browser. The data is often used to remember the client when the client returns to the hosted application at a later date. A session cookie is a special type of cookie used to remember the... |
|
V-214300
|
Medium |
The Apache web server must only accept client certificates issued by DOD PKI or DoD-approved PKI Certification Authorities (CAs). |
Non-DOD approved PKIs have not been evaluated to ensure that they have security controls and identity vetting procedures in place that are sufficient for DOD systems to rely on the identity asserted in the certificate. PKIs lacking sufficient security controls and identity vetting procedures risk being compromised and issuing certificates... |
|
V-214299
|
Medium |
The Apache web server application, libraries, and configuration files must only be accessible to privileged users. |
The Apache web server can be modified through parameter modification, patch installation, upgrades to the Apache web server or modules, and security parameter changes. With each of these changes, there is the potential for an adverse effect such as a denial of service (DoS), Apache web server instability, or hosted... |
|
V-214298
|
Medium |
Non-privileged accounts on the hosting system must only access Apache web server security-relevant information and functions through a distinct administrative account. |
By separating Apache web server security functions from non-privileged users, roles can be developed that can then be used to administer the Apache web server. Forcing users to change from a non-privileged account to a privileged account when operating on the Apache web server or on security-relevant information forces users... |
|
V-214297
|
Medium |
The Apache web server must restrict inbound connections from nonsecure zones. |
Remote access to the Apache web server is any access that communicates through an external, non-organization-controlled network. Remote access can be used to access hosted applications or to perform management functions.
A web server can be accessed remotely and must be capable of restricting access from what the DoD defines... |
|
V-214296
|
Medium |
The Apache web server must set an inactive timeout for sessions. |
Leaving sessions open indefinitely is a major security risk. An attacker can easily use an already authenticated session to access the hosted application as the previously authenticated user. By closing sessions after a set period of inactivity, the Apache web server can make certain that those sessions that are not... |
|
V-214295
|
Medium |
The Apache web server must set an absolute timeout for sessions. |
Leaving sessions open indefinitely is a major security risk. An attacker can easily use an already authenticated session to access the hosted application as the previously authenticated user. By closing sessions after an absolute period of time, the user is forced to reauthenticate, guaranteeing the session is still in use.... |

Medium |
The Apache web server must display a default hosted application web page, not a directory listing, when a requested web page cannot be found. |
The goal is to completely control the web user's experience in navigating any portion of the web document root directories. Ensuring all web content directories have at least the equivalent of an index.html file is a significant factor to accomplish this end.
Enumeration techniques, such as URL parameter manipulation, rely... |
|
V-214291
|
Medium |
The Apache web server must be tuned to handle the operational requirements of the hosted application. |
A denial of service (DoS) can occur when the Apache web server is so overwhelmed that it can no longer respond to additional requests. A web server not properly tuned may become overwhelmed and cause a DoS condition even with expected traffic from users. To avoid a DoS, the Apache... |
|
V-214290
|
Medium |
The Apache web server document directory must be in a separate partition from the Apache web servers system files. |
A web server is used to deliver content on the request of a client. The content delivered to a client must be controlled, allowing only hosted application files to be accessed and delivered. To allow a client access to system files of any type is a major security risk that... |
|
V-214289
|
Medium |
The Apache web server must augment re-creation to a stable and known baseline. |
Making certain that the web server has not been updated by an unauthorized user is always a concern. Adding patches, functions, and modules that are untested and not part of the baseline opens the possibility for security risks. The web server must offer, and not hinder, a method that allows... |
|
V-214288
|
Medium |
Cookies exchanged between the Apache web server and client, such as session cookies, must have security settings that disallow cookie access outside the originating Apache web server and hosted application. |
Cookies are used to exchange data between the web server and the client. Cookies, such as a session cookie, may contain session information and user credentials used to maintain a persistent connection between the user and the hosted application since HTTP/HTTPS is a stateless protocol.
When the cookie parameters are... |
|
V-214287
|
Medium |
Only authenticated system administrators or the designated PKI Sponsor for the Apache web server must have access to the Apache web servers private key. |
The web server's private key is used to prove the identity of the server to clients and securely exchange the shared secret key used to encrypt communications between the web server and clients.
By gaining access to the private key, an attacker can pretend to be an authorized server and... |
|
V-214286
|
Medium |
The Apache web server must perform RFC 5280-compliant certification path validation. |
A certificate's certification path is the path from the end entity certificate to a trusted root certification authority (CA). Certification path validation is necessary for a relying party to make an informed decision regarding acceptance of an end entity certificate. Certification path validation includes checks such as certificate issuer trust,... |

Medium |
The Apache web server must be configured to use a specified IP address and port. |
The web server must be configured to listen on a specified IP address and port. Without specifying an IP address and port for the web server to use, the web server will listen on all IP addresses available to the hosting server. If the web server has multiple IP addresses,... |
|
V-214284
|
Medium |
Users and scripts running on behalf of users must be contained to the document root or home directory tree of the Apache web server. |
A web server is designed to deliver content and execute scripts or applications on the request of a client or user. Containing user requests to files in the directory tree of the hosted web application and limiting the execution of scripts and applications guarantees that the user is not accessing... |
|
V-214283
|
Medium |
The Apache web server must have resource mappings set to disable the serving of certain file types. |
Resource mapping is the process of tying a particular file type to a process in the web server that can serve that type of file to a requesting client and to identify which file types are not to be delivered to a client.
By not specifying which files can and... |
|
V-214282
|
Medium |
The Apache web server must allow mappings to unused and vulnerable scripts to be removed. |
Scripts allow server-side processing on behalf of the hosted application user or as processes needed in the implementation of hosted applications. Removing scripts not needed for application operation or deemed vulnerable helps to secure the web server.
To ensure scripts are not added to the web server and run maliciously,... |
|
V-214281
|
Medium |
The Apache web server must have Multipurpose Internet Mail Extensions (MIME) that invoke operating system shell programs disabled. |
Controlling what a user of a hosted application can access is part of the security posture of the web server. Any time a user can access more functionality than is needed for the operation of the hosted application poses a security issue. A user with too much access can view... |
|
V-214280
|
Medium |
The Apache web server must not perform user management for hosted applications. |
User management and authentication can be an essential part of any application hosted by the web server. Along with authenticating users, the user management function must perform several other tasks such as password complexity, locking users after a configurable number of failed logons, and management of temporary and emergency accounts.... |
|
V-214279
|
Medium |
The Apache web server must produce log records containing sufficient information to establish what type of events occurred. |
Apache web server logging capability is critical for accurate forensic analysis. Without sufficient and accurate information, a correct replay of the events cannot be determined.
Ascertaining the correct type of event that occurred is important during forensic analysis. The correct determination of the event and when it occurred is important... |
|
V-214278
|
Medium |
The Apache web server must use encryption strength in accordance with the categorization of data hosted by the Apache web server when remote connections are provided. |
The Apache web server has several remote communications channels. Examples are user requests via http/https, communication to a backend database, and communication to authenticate users. The encryption used to communicate must match the data that is being retrieved or presented.
Methods of communication are "http" for publicly displayed information, "https"... |
