Prestashop versions 1.7.6.4 and below suffer from code execution, cross site request forgery, and cross site scripting vulnerabilities.

DCNM exposes a file upload servlet (FileUploadServlet) at /fm/fileUpload. An authenticated user can abuse this servlet to upload a WAR to the Apache Tomcat webapps directory and achieve remote code execution as root. This module exploits two other vulnerabilities, CVE-2019-1619 for authentication bypass on versions 10.4(2) and below, and CVE-2019-1622 (information disclosure) to obtain the correct directory for the WAR file upload. This module was tested on the DCNM Linux virtual appliance 10.4(2), 11.0(1) and 11.1(1), and should work on a few versions below 10.4(2). Only version 11.0(1) requires authentication to exploit (see References to understand why).

IBM Bigfix Platform version 9.5.9.62 suffers from an arbitrary file upload vulnerability as root that can achieve remote code execution.

Linear eMerge E3 versions 1.00-06 and below arbitrary file upload remote root code execution exploit.

This Metasploit module exploits an underflow vulnerability in PHP-FPM versions 7.1.x below 7.1.33, 7.2.x below 7.2.24 and 7.3.x below 7.3.11 of PHP-FPM on Nginx. Only servers with certain Nginx + PHP-FPM configurations are exploitable. This is a port of the original neex's exploit code (see refs). First, it detects the correct parameters (Query String Length and custom header length) needed to trigger code execution. This step determines if the target is actually vulnerable (Check method). Then, the exploit sets a series of PHP INI directives to create a file locally on the target, which enables code execution through a query string parameter. This is used to execute normal payload stagers. Finally, this module does some cleanup by killing local PHP-FPM workers (those are spawned automatically once killed) and removing the created local file.

rConfig version 3.93 suffers from an authenticated ajaxAddTemplate.php remote code execution vulnerability.

PHPKB Multi-Language 9 suffers from an image-upload.php remote authenticated code execution vulnerability.

The Horde_Data module version 2.1.4 (and before) present in Horde Groupware version 5.2.22 allows authenticated users to inject arbitrary PHP code thus achieving remote code execution the server hosting the web application.

Pandora FMS version 7.0NG suffers from a net_tools.php remote code execution vulnerability.

This Metasploit module exploits a preauth Server-Side Template Injection vulnerability that leads to remote code execution in PlaySMS before version 1.4.3. This issue is caused by double processing a server-side template with a custom PHP template system called TPL which is used in the PlaySMS template engine at src/Playsms/Tpl.php:_compile(). The vulnerability is triggered when an attacker supplied username with a malicious payload is submitted. This malicious payload is then stored in a TPL template which when rendered a second time, results in code execution.

This Metasploit module exploits a vulnerability found in Pandora FMS 7.0NG and lower. net_tools.php in Pandora FMS 7.0NG allows remote attackers to execute arbitrary OS commands.

This Metasploit module exploits one of two PHP injection vulnerabilities in the ThinkPHP web framework to execute code as the web user. Versions up to and including 5.0.23 are exploitable, though 5.0.23 is vulnerable to a separate vulnerability. The module will automatically attempt to detect the version of the software. Tested against versions 5.0.20 and 5.0.23 as can be found on Vulhub.

rConfig version 3.9.4 searchField unauthenticated remote root code execution exploit.

This Metasploit module exploits command injection vulnerability in v-list-user-backups bash script file. Low privileged authenticated users can execute arbitrary commands under the context of the root user. An authenticated attacker with a low privileges can inject a payload in the file name starts with dot. During the user backup process, this file name will be evaluated by the v-user-backup bash scripts. As result of that backup process, when an attacker try to list existing backups injected payload will be executed.

This Metasploit module exploits an authenticated command injection vulnerability in the v-list-user-backups bash script file in Vesta Control Panel to gain remote code execution as the root user.

This Metasploit module exploits a command injection vulnerability in the tdpServer daemon (/usr/bin/tdpServer), running on the router TP-Link Archer A7/C7 (AC1750), hardware version 5, MIPS Architecture, firmware version 190726. The vulnerability can only be exploited by an attacker on the LAN side of the router, but the attacker does not need any authentication to abuse it. After exploitation, an attacker will be able to execute any command as root, including downloading and executing a binary from another host. This vulnerability was discovered and exploited at Pwn2Own Tokyo 2019 by the Flashback team.

This Metasploit module exploits two vulnerabilities affecting Unraid 6.8.0. An authentication bypass is used to gain access to the administrative interface, and an insecure use of the extract PHP function can be abused for arbitrary code execution as root.

107 bytes small Linux/x86 shellcode that adds the user 'ctl' with the password 'ctl' to the /etc/passwd file with the UID and GID of 0 (root). This shellcode uses legacy passwd functionality. Therefore the /etc/shadow file does not need to be accessed or modified.

155 bytes small Linux/x86 shellcode that has a MMX stub decoder that dynamically decodes the payload in memory. The FPU GetPC technique is used to determine the offset from EIP dynamically in running memory. Once decoded. this shellcode adds the user 'ctl' with the password 'ctl' to the /etc/passwd file with the UID and GID of 0 (root). This shellcode uses legacy passwd functionality. Therefore the /etc/shadow file does not need to be accessed or modified.

This exploit uses the Cable Haunt vulnerability to open a shell for the Sagemcom F@ST 3890 (50_10_19-T1) cable modem. The exploit serves a website that sends a malicious websocket request to the cable modem. The request will overflow a return address in the spectrum analyzer of the cable modem and using a rop chain start listening for a tcp connection on port 1337. The server will then send a payload over this tcp connection and the modem will start executing the payload. The payload will listen for commands to be run in the eCos shell on the cable modem and redirect STDOUT to the tcp connection.
