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.
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.
This vulnerability allows remote attackers to bypass authentication on affected installations of PaperCut NG 22.0.5 (Build 63914). Authentication is not required to exploit this vulnerability. The specific flaw exists within the SetupCompleted class. The issue results from improper access control. An attacker can leverage this vulnerability to bypass authentication and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-18987.
This vulnerability allows remote attackers to bypass authentication on affected installations of PaperCut NG 22.0.5 (Build 63914). Authentication is not required to exploit this vulnerability. The specific flaw exists within the SecurityRequestFilter class. The issue results from improper implementation of the authentication algorithm. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-19226.
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.
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.
Cross-site request forgery (CSRF) vulnerability in the admin UI in Papercut MF and NG before 14.1 (Build 26983) allows remote attackers to hijack the authentication of administrators via unspecified vectors.
