CVE-2024-3037

Existe una vulnerabilidad de eliminación arbitraria de archivos en PaperCut NG/MF que solo afecta a los servidores Windows con Web Print habilitado. Esta vulnerabilidad requiere acceso a la consola o inicio de sesión local al servidor PaperCut NG/MF (por ejemplo, miembro de un grupo de administración de dominio).

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.

This vulnerability allows local attackers to escalate privileges on affected installations of PaperCut NG. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the PCWebService. By creating a symbolic link, an attacker can abuse the service to delete a file. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM.
