An authentication bypass exists in PaperCut NG versions 22.0.12 and prior that could allow a remote, unauthenticated attacker to upload arbitrary files to the PaperCut NG host’s file storage. This could exhaust system resources and prevent the service from operating as expected.

The version of PaperCut NG installed on the remote Windows host is affected by multiple vulnerabilities, as follows:

    - An authentication bypass exists that could allow a remote, unauthenticated attacker to upload arbitrary files to       the PaperCut host’s file storage. This could exhaust system resources and prevent the service from operating as       expected. (CVE-2023-3486)

    - A path traversal, enabling attackers to upload, read, or delete arbitrary files. This leads to remote code       execution when external device integration is enabled (a very common configuration). (CVE-2023-39143)

    - A third party library issue in pgjdbc. pgjdbc is the offical PostgreSQL JDBC Driver. A security hole was found in       the jdbc driver for postgresql database while doing security research. The system using the postgresql library       will be attacked when attacker control the jdbc url or properties. pgjdbc instantiates plugin instances based on       class names provided via authenticationPluginClassName, sslhostnameverifier, socketFactory, sslfactory,       sslpasswordcallback connection properties. However, the driver did not verify if the class implements the expected       interface before instantiating the class. This can lead to code execution loaded via arbitrary classes. Users       using plugins are advised to upgrade. There are no known workarounds for this issue. (CVE-2022-21724)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The PaperCut MF running on the remote host is affected by an authentication bypass vulnerability. An unauthenticated, remote attacker can exploit this, via a specially crafted message, to bypass access control to upload arbitrary files to the 'upload' directory of the product. This can exhaust system resources and prevent the service from operating as expected.
