Paessler PRTG Network Monitor Cross-Site Scripting Authentication Bypass Vulnerability. This vulnerability allows remote attackers to bypass authentication on affected installations of Paessler PRTG Network Monitor. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the web console. The issue results from the lack of proper validation of user-supplied data, which can lead to the injection of an arbitrary script. An attacker can leverage this vulnerability to bypass authentication on the system. . Was ZDI-CAN-21182.

A cross-site request forgery (CSRF) token bypass was identified in PRTG 23.2.84.1566 and earlier versions that allows remote attackers to perform actions with the permissions of a victim user, provided the victim user has an active session and is induced to trigger the malicious request. This could force PRTG to execute different actions, such as creating new users. The severity of this vulnerability is high and received a score of 8.8 CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

A path traversal vulnerability was identified in the SQL v2 sensors in PRTG 23.2.84.1566 and earlier versions where an authenticated user with write permissions could trick the SQL v2 sensors into behaving differently for existing files and non-existing files. This made it possible to traverse paths, allowing the sensor to execute files outside the designated custom sensors folder. The severity of this vulnerability is medium and received a score of 4.7 CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L

PRTG Network Monitor through 22.2.77.2204 does not prevent custom input for a device’s icon, which can be modified to insert arbitrary content into the style tag for that device. When the device page loads, the arbitrary Cascading Style Sheets (CSS) data is inserted into the style tag, loading malicious content. Due to PRTG Network Monitor preventing “characters, and from modern browsers disabling JavaScript support in style tags, this vulnerability could not be escalated into a Cross-Site Scripting vulnerability.

A Write to Arbitrary Location in Disk vulnerability exists in PRTG Network Monitor 19.1.49 and below that allows attackers to place files in arbitrary locations with SYSTEM privileges (although not controlling the contents of such files) due to insufficient sanitisation when passing arguments to the phantomjs.exe binary. In order to exploit the vulnerability, remote authenticated administrators need to create a new HTTP Full Web Page Sensor and set specific settings when executing the sensor.

PRTG Network Monitor before 18.2.40.1683 allows remote unauthenticated attackers to create users with read-write privileges (including administrator). A remote unauthenticated user can craft an HTTP request and override attributes of the 'include' directive in /public/login.htm and perform a Local File Inclusion attack, by including /api/addusers and executing it. By providing the 'id' and 'users' parameters, an unauthenticated attacker can create a user with read-write privileges (including administrator).

PRTG Network Monitor before 18.3.44.2054 allows a remote authenticated attacker (with read-write privileges) to execute arbitrary code and OS commands with system privileges. When creating an HTTP Advanced Sensor, the user's input in the POST parameter 'proxyport_' is mishandled. The attacker can craft an HTTP request and override the 'writeresult' command-line parameter for HttpAdvancedSensor.exe to store arbitrary data in an arbitrary place on the file system. For example, the attacker can create an executable file in the \Custom Sensors\EXE directory and execute it by creating EXE/Script Sensor.
