# Apache HTTP Server Vulnerability Alert.
---

This incident type refers to the detection of vulnerabilities in the Apache HTTP Server. The Apache HTTP Server is a widely used web server application that serves web content to clients. A vulnerability in the server can potentially be exploited by attackers to gain unauthorized access to the server or the data it hosts. This incident type involves the detection of such vulnerabilities and the generation of an alert to prompt action to mitigate the risk associated with the vulnerability.

### Parameters
```shell
export PACKAGE_NAME="PLACEHOLDER"

export CONFIGURATION_FILE_PATH="PLACEHOLDER"

export LATEST_APACHE_HTTP_SERVER_VERSION="PLACEHOLDER"
```

## Debug

### Check Apache HTTP Server version
```shell
httpd -v
```

### Check for any suspicious activities on the server
```shell
tail -f /var/log/secure
```

### Check if Apache HTTP Server is running
```shell
systemctl status httpd
```

### Check Apache HTTP Server logs for any errors
```shell
journalctl -u httpd -b
```

### Check for any recently installed packages that may have caused the vulnerability
```shell
yum history list | grep ${PACKAGE_NAME}
```

### Check for any security updates available for Apache HTTP Server
```shell
yum check-update httpd
```

### Check Apache HTTP Server configuration file for any misconfigurations
```shell
httpd -t -f ${CONFIGURATION_FILE_PATH}
```

## Repair

### Update Apache HTTP Server to the latest version that addresses the vulnerability.
```shell


#!/bin/bash



# Define variables for the script

APACHE_VERSION=${LATEST_APACHE_HTTP_SERVER_VERSION}



# Stop Apache HTTP Server

sudo systemctl stop apache2



# Update the Apache HTTP Server package to the latest version

sudo apt-get update && sudo apt-get install apache2=$APACHE_VERSION



# Restart Apache HTTP Server

sudo systemctl start apache2


```

This incident type refers to the detection of vulnerabilities in the Apache HTTP Server. The Apache HTTP Server is a widely used web server application that serves web content to clients. A vulnerability in the server can potentially be exploited by attackers to gain unauthorized access to the server or the data it hosts. This incident type involves the detection of such vulnerabilities and the generation of an alert to prompt action to mitigate the risk associated with the vulnerability.


This incident type refers to an unauthorized access to directories in Apache HTTPD, which is a widely used web server software. It means that someone was able to access files or directories that they were not supposed to, without having proper authorization. This type of incident can potentially lead to sensitive data being exposed or even stolen, and can compromise the security of the server and the applications running on it.


Unauthorized Directory Access in Apache HTTPD.

The Slowloris Attack is a type of Denial of Service (DoS) attack that exploits a vulnerability in the Apache web server. It works by sending HTTP requests to the server and keeping those connections open for as long as possible, thereby using up all the available resources of the server and rendering it unresponsive to legitimate requests. As a result, the server becomes slow or unresponsive, causing downtime for the affected website or service. This type of attack can be detected and mitigated by implementing specific security measures and tools.


Slowloris Attack Detected on Apache server.

This incident type refers to the detection of SQL injection attempts in Apache web server logs. SQL injection is a type of cyber attack that exploits vulnerabilities in web applications allowing attackers to execute malicious SQL statements. In this incident, attackers are attempting to inject SQL code into the URI (Uniform Resource Identifier) of an Apache web server, potentially compromising the server's security and exposing sensitive information.


Apache SQL Injection Attempts in URI Incident

This incident type refers to a security vulnerability in the SSL/TLS configuration of the Apache HTTP Server, which can leave the server and its users vulnerable to attacks. The SSL/TLS configuration is responsible for encrypting the communication between the server and its clients, and if it is not configured properly, it can be exploited by hackers to intercept or modify sensitive data. This type of incident requires immediate attention from software engineers to ensure that the SSL/TLS configuration is properly configured to prevent any potential security threats.


Inadequate SSL/TLS Configuration for Apache HTTP Server.

This incident type refers to a situation where the number of child processes created by an Apache server reaches a high threshold, causing performance issues and potentially leading to server crashes. This can occur due to factors such as high traffic volume or misconfigured server settings. The incident requires investigation and mitigation to restore normal server functioning and prevent future occurrences.

export PACKAGE_NAME="PLACEHOLDER"

export CONFIGURATION_FILE_PATH="PLACEHOLDER"

export LATEST_APACHE_HTTP_SERVER_VERSION="PLACEHOLDER"
```


### Check Apache HTTP Server version

```shell
httpd -v
```

### Check for any suspicious activities on the server

```shell
tail -f /var/log/secure
```

### Check if Apache HTTP Server is running

```shell
systemctl status httpd
```

### Check Apache HTTP Server logs for any errors

```shell
journalctl -u httpd -b
```

### Check for any recently installed packages that may have caused the vulnerability

```shell
yum history list | grep ${PACKAGE_NAME}
```

### Check for any security updates available for Apache HTTP Server

```shell
yum check-update httpd
```

### Check Apache HTTP Server configuration file for any misconfigurations

```shell
httpd -t -f ${CONFIGURATION_FILE_PATH}
```


### Update Apache HTTP Server to the latest version that addresses the vulnerability.

```shell


#!/bin/bash



# Define variables for the script

APACHE_VERSION=${LATEST_APACHE_HTTP_SERVER_VERSION}



# Stop Apache HTTP Server

sudo systemctl stop apache2



# Update the Apache HTTP Server package to the latest version

sudo apt-get update && sudo apt-get install apache2=$APACHE_VERSION



# Restart Apache HTTP Server

sudo systemctl start apache2


```
