PaperCut NG/MF contains an observable timing discrepancy in its authentication component. An unauthenticated remote attacker can exploit this vulnerability to perform username enumeration by measuring response times during login attempts. The system executes a password hash comparison only when a valid account is supplied, creating a measurable timing oracle that reveals account existence.

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.

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.

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

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.
