A race condition exists in PaperCut MF when processing badge-swipe data from certain HP multifunction devices. Under specific network conditions involving dropped packets and out-of-order sequence counters, the server may incorrectly process fragmented data chunks. If a sequence reset notification fails to reach the server, the server may reject the initial data chunk while erroneously accepting subsequent chunks before a connection reset completes. This leads to the registration of a truncated badge ID string. While this typically results in an authentication failure, the vulnerability is compounded in environments utilizing custom badge-ID post-processing scripts. In such configurations, the truncated string may be transformed into a valid ID belonging to a different user, leading to unauthorized session establishment (Incorrect User Login) on the device.

The PaperCut NG/MF (specifically, the embedded application for Konica Minolta devices) is vulnerable to session hijacking. The PaperCut NG/MF Embedded application is a software interface that runs directly on the touch screen of a multi-function device. It was internally discovered that the communication channel between the embedded application and the server was insecure, which could leak data including sensitive information that may be used to mount an  attack on the device. Such an attack could potentially be used to steal data or to perform a phishing attack on the end user.

Multiple cross-site scripting (XSS) vulnerabilities in PaperCut NG/MF before 25.0.10 allow authenticated administrator users to inject arbitrary web script or HTML code via different UI fields. This could be used to compromise other admininistrator's sessions or perform unauthorized actions via the administrator's authenticated context (e.g. requires an active login session).

PaperCut Print Deploy is an optional component that integrates with PaperCut NG/MF which simplifies printer deployment and management. When the component is deployed to an environment, the customer has an option to configure the system to use a self-signed certificate. If the customer does not fully configure the system to leverage the trust database on the clients, it opens up the communication between clients and the server to man-in-the-middle attacks.  It was discovered that certain parts of the documentation related to the configuration of SSL in Print Deploy were lacking, which could potentially contribute to a misconfiguration of the Print Deploy client installation. PaperCut strongly recommends to use valid certificates to secure installations and to follow the updated documentation to ensure the correct SSL configuration. Those who use private CAs and/or self-signed certificates should make sure to copy their Certification Authority certificate, or their self signed certificate if using only one, to the trust store of their operating system and to the Java key store

A reflected cross-site scripting (XSS) vulnerability exists in PaperCut NG/MF. This issue can be used to execute specially created JavaScript payloads in the browser. A user must click on a malicious link for this issue to occur.

PaperCut NG print.script.sandboxed Exposed Dangerous Function 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 management of the print.script.sandboxed setting. The issue results from the exposure of a dangerous function. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-20965.

An arbitrary file creation vulnerability exists in PaperCut NG/MF that only affects Windows servers with Web Print enabled. This specific flaw exists within the web-print.exe process, which can incorrectly create files that don’t exist when a maliciously formed payload is provided. This can be used to flood disk space and result in a Denial of Service (DoS) attack. Note: This CVE has been split from CVE-2024-4712.

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 via the web-print-hot-folder. Important: In most installations, this risk is mitigated by the default Windows Server configuration, which restricts local login access to Administrators only. However, this vulnerability could pose a risk to customers who allow non-administrative users to log into the local console of the Windows environment hosting the PaperCut NG/MF application server. Update: This CVE has been updated in May 2025 to update the fixed version and fix process. Please refer to the May 2025 Security Bulletin. Note: This CVE has been split from CVE-2024-3037.

An arbitrary file creation vulnerability exists in PaperCut NG/MF that only affects Windows servers with Web Print enabled. This specific flaw exists within the image-handler process, which can incorrectly create files that don’t exist when a maliciously formed payload is provided. This can lead to local privilege escalation. Note: This CVE has been split into two (CVE-2024-4712 and CVE-2024-8405) 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 network 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.

The `PaperCutNG Mobility Print` version 1.0.3512 application allows an unauthenticated attacker to perform a CSRF attack on an instance administrator to configure the clients host (in the "configure printer discovery" section). This is possible because the application has no protections against CSRF attacks, like Anti-CSRF tokens, header origin validation, samesite cookies, etc.
