This allows attackers to use a maliciously formed API request to gain access to an API authorization level with elevated privileges. This applies to a small subset of PaperCut NG/MF API calls.

PaperCut MF/NG contains an improper access control vulnerability within the SetupCompleted class that allows authentication bypass and code execution in the context of system.

PaperCut MF before 18.3.6 and PaperCut NG before 18.3.6 allow script injection via the user interface, aka PC-15163.

An unspecified vulnerability in the application server in PaperCut MF and NG versions 18.3.8 and earlier and versions 19.0.3 and earlier allows remote attackers to execute arbitrary code via an unspecified vector.

PaperCut NG and PaperCut MF before 22.1.3 are vulnerable to path traversal which enables attackers to read, delete, and upload arbitrary files.

An unsafe dynamic class loading vulnerability exists in the database connection utilities of PaperCut MF and PaperCut NG. The application instantiates database driver classes based on configurable driver names without validating against an allowlist of approved drivers. If an attacker can manipulate system configuration parameters, this enables the execution of arbitrary Java bytecode residing on the application classpath under the security context of the PaperCut server process.

An improper access control vulnerability exists in the web management interface of PaperCut MF and PaperCut NG. Under specific conditions, unauthenticated remote requests targeting administrative functions can trigger backend actions prior to the completion of access validation checks. This allows an unauthenticated remote attacker to modify certain system configurations.

A Cross-Site Request Forgery (CSRF) vulnerability has been identified in PaperCut NG/MF, which, under specific conditions, could potentially enable an attacker to alter security settings or execute arbitrary code. This could be exploited if the target is an admin with a current login session. Exploiting this would typically involve the possibility of deceiving an admin into clicking a specially crafted malicious link, potentially leading to unauthorized changes.

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.

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.

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.

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

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 vulnerability exists in the PaperCut NG/MF platform's device-scripting functionality due to insufficient sanitization and access restrictions within the embedded execution engine. An authenticated user with administrative access to the management interface can supply a malicious script that escapes the runtime sandbox.

A successful execution enables an attacker to run unauthorized operating system commands with administrative privileges on the host operating system.

Unspecified vulnerability in the print release functionality in PaperCut MF before 14.1 (Build 26983) has unknown impact and remote vectors, related to embedded MFPs.

PaperCut NG/MF contains an improper authentication vulnerability that could allow remote attackers to bypass authentication on affected installations via the SecurityRequestFilter class.

An insecure process execution vulnerability exists in the pc-printer-updater.exe component of the PaperCut Print Deploy Client for Windows. The application, which typically operates with high-level system privileges, attempts to perform an internal validation check by invoking a secondary system utility using an unqualified file reference.

Because the application does not specify an absolute path to this utility, it relies on the operating system's default search order to locate the executable. Under specific conditions, a local attacker with the ability to modify directories within the system's search path could plant a malicious binary that mimics the expected utility. This could result in the malicious code being executed with SYSTEM privileges, leading to a full compromise of the affected host.

An improper limitation of a pathname to a restricted directory (path traversal) vulnerability in the Scan-to-Fax component of PaperCut NG and PaperCut MF allows an authenticated administrator to execute arbitrary commands on the underlying host via crafted fax provider settings.

This vulnerability potentially allows unauthorized write operations which may lead to remote code execution. An attacker must already have authenticated admin access and knowledge of both an internal system identifier and details of another valid user to exploit this.

This vulnerability allows an already authenticated admin user to create a malicious payload that could be leveraged for remote code execution on the server hosting the PaperCut NG/MF application server.
