Operating Systems. Could not start the Apache2. You will get this generic error if there is any problem with starting the Apache service. In order to see what is really causing the problem you should follow the instructions for Running Apache for Windows from the Command Prompt. If you are having problems with the service, it is suggested you follow the instructions below to try starting httpd. Running Apache as a service is usually the recommended way to use it, but it is sometimes easier to work from the command line, especially during initial configuration and testing.
This will open a console window and start Apache inside it. If you don't have Apache installed as a service, the window will remain visible until you stop Apache by pressing Control-C in the console window where Apache is running in. The server will exit in a few seconds. However, if you do have Apache installed as a service, the shortcut starts the service. If the Apache service is running already, the shortcut doesn't do anything. If Apache is running as a service, you can tell it to stop by opening another console window and entering:.
Running as a service should be preferred over running in a console window because this lets Apache end any current operations and clean up gracefully. But if the server is running in a console window, you can only stop it by pressing Control-C in the same window. You can also tell Apache to restart. This forces it to reread the configuration file. Any operations in progress are allowed to complete without interruption. To restart Apache, either press Control-Break in the console window you used for starting Apache, or enter.
Change to the folder to which you installed Apache, type the command httpd. Then change to the logs folder, and review the error. When working with Apache it is important to know how it will find the configuration file. You can specify a configuration file on the command line in two ways:. In both of these cases, the proper ServerRoot should be set in the configuration file.
This built-in path is relative to the installation directory. Apache will then try to determine its ServerRoot by trying the following, in this order:. If you did not do a binary install, Apache will in some scenarios complain about the missing registry key. This warning can be ignored if the server was otherwise able to find its configuration file. The value of this key is the ServerRoot directory which contains the conf subdirectory.
When Apache starts it reads the httpd. If this file contains a ServerRoot directive which contains a different directory from the one obtained from the registry key above, Apache will forget the registry key and use the directory from the configuration file. If you copy the Apache directory or configuration files to a new location it is vital that you update the ServerRoot directive in the httpd.
Because these vulnerabilities are in a Java library, the cross-platform nature of Java means the vulnerabilities are exploitable on many platforms, including Windows, macOS, and Linux. As many Java-based applications can leverage Log4j 2 directly or indirectly, organizations should contact application vendors or ensure their Java applications are running the latest up-to-date version. Developers using Log4j 2 should ensure that they are incorporating the latest version of Log4j into their applications as soon as possible to protect users and organizations.
The vulnerabilities allow remote code execution by an unauthenticated attacker to gain complete access to a target system. It can be triggered when a specially crafted string is parsed and processed by the vulnerable Log4j 2 component. This could happen through any user provided input. Successful exploitation allows for arbitrary code execution in the targeted application.
Attackers do not need prior access to the system to log the string and can remotely cause the logging event by using commands like curl against a target system to log the malicious string in the application log. When processing the log, the vulnerable system reads the string and executes it, which in current attacks is used to execute the code from the malicious domain. Doing so can grant the attacker full access and control of the affected application.
Given the fact that logging code and functionalities in applications and services are typically designed to process a variety of external input data coming from upper layers and from many possible vectors, the biggest risk factor of these vulnerabilities is predicting whether an application has a viable attack vector path that will allow the malformed exploit string to reach the vulnerable Log4j 2 code and trigger the attack.
A common pattern of exploitation risk, for example, is a web application with code designed to process usernames, referrer, or user-agent strings in logs. These strings are provided as external input e. An attacker can send a malformed username or set user-agent with the crafted exploit string hoping that this external input will be processed at some point by the vulnerable Log4j 2 code and trigger code execution.
Figure 1. CVE and CE exploit vectors and attack chain. After further analysis of our services and products, below are a few mitigation strategies given by various Microsoft services.
The mitigation based on disabling message lookup functionality — through enabling the system property log4j2. Customers should still apply the latest security updates or apply other documented mitigation steps such as the removal of the JndiLookup. Microsoft recommends that all Customers upgrade to December release which has updated the Log4J library to 2. Azure Arc-enabled data services us Elasticsearch version 7.
However, your applications may use Log4J and be susceptible to these vulnerabilities. If you are not able to re-package your application with a newer version of Log4j and you are using Log4j versions 2. Note that this command will also restart your App Service hosted application.
In our investigation so far, we have not found any evidence that these services are vulnerable however customer applications running behind these services might be vulnerable to this exploit. We highly recommend customers to follow mitigations and workarounds mentioned in this blog to protect their applications. Additional guidance for Azure WAF is located here. Your instance may be vulnerable if you have installed an affected version of Log4j or have installed services that transitively depend on an affected version.
Open a browser and enter the IP address of your server. You should see the test web page. Step 9. Once you are ready to start serving your new web pages, re-enable that firewall rules, and they should be reachable from the Internet again.
