Title
Paessler PRTG Network Monitor SNMP Cross-Site Scripting Authentication Bypass Vulnerability
Summary
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.

CVE-2023-31452 (GCVE-0-2023-31452)
Vulnerability from nvd – Published: 2023-08-09 00:00 – Updated: 2024-10-10 16:17
VLAI
Summary
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

CVE-2023-31450 (GCVE-0-2023-31450)
Vulnerability from nvd – Published: 2023-08-09 00:00 – Updated: 2025-02-13 16:50

Summary
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

CVE-2022-35739 (GCVE-0-2022-35739)
Vulnerability from nvd – Published: 2022-10-25 00:00 – Updated: 2025-05-07 20:37
VLAI
Summary
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.
Severity
5.3 (Medium)

Title
Paessler PRTG Network Monitor SNMP Cross-Site Scripting Authentication Bypass Vulnerability
Summary
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.

Summary
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

CVE-2023-31452 (GCVE-0-2023-31452)
Vulnerability from cvelistv5 – Published: 2023-08-09 00:00 – Updated: 2024-10-10 16:17
VLAI
Summary
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

CVE-2022-35739 (GCVE-0-2022-35739)
Vulnerability from cvelistv5 – Published: 2022-10-25 00:00 – Updated: 2025-05-07 20:37
VLAI
Summary
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.
