Papercut: Security Vulnerabilities
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.

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.

CVE-2023-2533
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.
