An arbitrary file deletion vulnerability exists in PaperCut NG/MF, specifically affecting Windows servers with Web Print enabled. To exploit this vulnerability, an attacker must first obtain local login access to the Windows Server hosting PaperCut NG/MF and be capable of executing low-privilege code directly on the server.
Important: In most installations, this risk is mitigated by the default Windows Server configuration, which typically restricts local login access to Administrators only. However, this vulnerability could pose a risk to customers who allow non-administrative users to log in to the local console of the Windows environment hosting the PaperCut NG/MF application server.
Note: This CVE has been split into two separate CVEs (CVE-2024-3037 and CVE-2024-8404) and it’s been rescored with a "Privileges Required (PR)" rating of low, and “Attack Complexity (AC)” rating of low, reflecting the worst-case scenario where an Administrator has granted local login access to standard users on the host server.
PaperCut NG External User Lookup Code Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of PaperCut NG. Authentication is required to exploit this vulnerability.
The specific flaw exists within the External User Lookup functionality. The issue results from the lack of proper validation of a user-supplied string before using it to execute Java code. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-21013.
This vulnerability potentially allows local attackers to escalate privileges on affected installations of PaperCut NG. An attacker must have local write access to the C Drive. In addition, Print Archiving must be enabled or the attacker needs to encounter a misconfigured system. This vulnerability does not apply to PaperCut NG installs that have Print Archiving enabled and configured as per the recommended set up procedure. This specific flaw exists within the pc-pdl-to-image process. The process loads an executable from an unsecured location. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM
Note: This CVE has been rescored with a "Privileges Required (PR)" rating of low, and “Attack Complexity (AC)” rating of low, reflecting the worst-case scenario where an Administrator has granted local login access to standard network users on the host server.
A Path Traversal vulnerability exists in PaperCut NG before 22.1.1 and PaperCut MF before 22.1.1. Under specific conditions, this could potentially allow an authenticated attacker to achieve read-only access to the server's filesystem, because requests beginning with "GET /ui/static/..//.." reach getStaticContent in UIContentResource.class in the static-content-files servlet.
PaperCut NG allows for unauthenticated XMLRPC commands to be run by default. Versions 22.0.12 and below are confirmed to be affected, but later versions may also be affected due to lack of a vendor supplied patch.
PaperCut NG and PaperCut MF before 22.1.3 on Windows allow 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).
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.
