This module uses a stack-based buffer overflow vulnerability to deploy an agent in Ivanti Connect Secure that will run with the nr user privileges. First, this module will check if the target is an Ivanti Connect Secure appliance. If it is, it will determine if the target is vulnerable by retrieving it's version number using 2 different methods. Then, the module will try to leak the base address of the libdsplibs.so library. To perform this, a random endpoint will be registered in the local webserver. Then, the vulnerability will be used while bruteforcing the base address of the library in order to the execute a cURL command that will send the request to the registered random endpoint. Once the base address of the libdsplibs.so library is obtained, the vulnerability will be used one more time to deploy an agent.
This exploit leverages the CVE-2024-24401 and CVE-2024-24402 vulnerabilities in Nagios XI to fully compromise the system and gain total remote control. The monitoringwizard.php component of Nagios XI version 2024R1.01 is vulnerable to a critical SQL Injection, identified as CVE-2024-24401. Initially, the exploit targets this component, performing an SQL Injection to extract the administrator key (admin key). Before proceeding, it authenticates using an existing user, regardless of their privilege level, ensuring access to the system for subsequent stages. With the administrator key obtained, a new administrator user is created, along with an identity associated with this user, using the newly generated credentials. This identity enables reauthentication and the ability to perform elevated actions. Subsequently, the exploit executes arbitrary commands on the system using the privileges of the newly created administrator. Next, it installs an agent and escalates its privileges to root, exploiting the CVE-2024-24402 vulnerability. During this process, the exploit manages the npcd service binary: first, the original service is stopped, and a backup of the npcd binary is created in the /usr/local/nagios/bin/ directory as npcd.backup. Then, the agent binary is copied to the same directory under the name npcd, replacing the original binary. Finally, the npcd service is restarted to execute the agent. These steps result in a full system compromise, granting the attacker total remote control and the ability to execute arbitrary actions with root privileges.
This module exploits CVE-2024-5910 to reset the password of the admin. For doing this, it will craft a special request to the endpoint /OS/startup/restore/restoreAdmin.php. After getting the admin password, it will authenticate with the admin credentials and it will exploit CVE-2024-9464 in order to deploy an agent. The exploitation of CVE-2024-9464 consists in crafting a special request to the endpoint /bin/CronJobs.php. As an authenticated user we can abuse this endpoint for inserting commands in the table cronjobs from pandb. After inserting the command into this table, the target will execute it.

This module chains 4 vulnerabilities to deploy an agent in a Linux target system that will run with the cups-browsed daemon user privileges. The first vulnerability is cups-browsed which binds on UDP INADDR_ANY:631 trusting any packet from any source to trigger a Get-Printer-Attributes IPP request to an attacker controlled URL. The second vulnerability is in libcupsfilters were function cfGetPrinterAttributes5 does not validate or sanitize the IPP attributes returned from an IPP server, providing attacker controlled data to the rest of the CUPS system. The third vulnerability is in libppd were function ppdCreatePPDFromIPP2 does not validate or sanitize the IPP attributes when writing them to a temporary PPD file, allowing the injection of attacker controlled data in the resulting PPD. The last vulnerability is in cups-filters were foomatic-rip allows arbitrary command execution via the FoomaticRIPCommandLine PPD parameter. This module will start a fake IPP Server that will be used to deliver the payload to exploit the last 3 vulnerabilities. This will create a fake printer on the system. Then, it will send a packet to the target to exploit the first vulnerability. Finally, the attack chain will be triggered by sending an HTTP request to the CUPS Management Interface to print a test page on the fake printer, which in turn, will execute the commands that will deploy the agent. The url for the CUPS Management Interface can be set with the CUPS_MANAGEMENT_URL parameter. If no value is specified, then http and tcp port 631 will be used. If the final step fails (i.e. if the CUPS Management Interface only listens in the local interface) the module will keep running for a period of time waiting for the target system to create a print job on the fake printer that will deliver the attack to deploy the agent. The wait time (in seconds) can be changed with the ATTACK_TIMEOUT parameter. The default/minimal value is 90 seconds.
In GeoServer prior to versions 2.23.6, 2.24.4, and 2.25.2, multiple OGC request parameters allow Remote Code Execution (RCE) by unauthenticated users through specially crafted input against a default GeoServer installation due to unsafely evaluating property names as XPath expressions. The GeoTools library API that GeoServer calls evaluates property/attribute names for feature types in a way that unsafely passes them to the commons-jxpath library which can execute arbitrary code when evaluating XPath expressions. This XPath evaluation is intended to be used only by complex feature types (i.e., Application Schema data stores) but is incorrectly being applied to simple feature types as well which makes this vulnerability apply to all GeoServer instances. In order to exploit this vulnerability, this module sends an evil XPath expression that after being processed by the commons-jxpath library allows us to deploy an agent.
