| CVE | Severity | CVSS | Summary | Published |
|---|---|---|---|---|
| CVE-2025-67835(opens NVD record) | Medium | 6.5 | Paessler PRTG Network Monitor before 25.4.114 allows Denial-of-Service (DoS) by an authenticated attacker via the Notification Contacts functionality. | Jan 14, 2026 |
| CVE-2025-67834(opens NVD record) | Medium | 5.4 | Paessler PRTG Network Monitor before 25.4.114 allows XSS by an unauthenticated attacker via the filter parameter. | Jan 14, 2026 |
| CVE-2025-67833(opens NVD record) | Medium | 6.1 | Paessler PRTG Network Monitor before 25.4.114 allows XSS by an unauthenticated attacker via the tag parameter. | Jan 14, 2026 |
| CVE-2024-12833(opens NVD record) | Medium | 6.1 | Paessler PRTG Network Monitor SNMP Cross-Site Scripting Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of Paessler PRTG Network Monitor. Some user interaction on the part of an administrator is required to exploit this vulnerability. The specific flaw exists within the PRTG Network Monitor web interface. 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-23371. | Feb 11, 2025 |
| CVE-2023-51630(opens NVD record) | Medium | 6.1 | 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. | Feb 8, 2024 |
| CVE-2023-32782(opens NVD record) | High | 7.2 | A command injection was identified in PRTG 23.2.84.1566 and earlier versions in the Dicom C-ECHO sensor where an authenticated user with write permissions could abuse the debug option to write new files that could potentially get executed by the EXE/Script sensor. The severity of this vulnerability is high and received a score of 7.2 CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H | Aug 9, 2023 |
| CVE-2023-32781(opens NVD record) | High | 7.2 | A command injection vulnerability was identified in PRTG 23.2.84.1566 and earlier versions in the HL7 sensor where an authenticated user with write permissions could abuse the debug option to write new files that could potentially get executed by the EXE/Script sensor. The severity of this vulnerability is high and received a score of 7.2 CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H | Aug 9, 2023 |
| CVE-2023-31452(opens NVD record) | High | 8.8 | 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 | Aug 9, 2023 |
| CVE-2023-31450(opens NVD record) | Medium | 4.7 | 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 | Aug 9, 2023 |
| CVE-2023-31449(opens NVD record) | Medium | 4.7 | A path traversal vulnerability was identified in the WMI Custom sensor in PRTG 23.2.84.1566 and earlier versions where an authenticated user with write permissions could trick the WMI Custom sensor 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 | Aug 9, 2023 |
| CVE-2023-31448(opens NVD record) | Medium | 4.7 | A path traversal vulnerability was identified in the HL7 sensor in PRTG 23.2.84.1566 and earlier versions where an authenticated user with write permissions could trick the HL7 sensor 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 | Aug 9, 2023 |
| CVE-2022-35739(opens NVD record) | Medium | 5.3 | 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. | Oct 25, 2022 |
