| CVE-2023-27351 | Hig | 0.74 | 7.5 | 0.87 | KEV | Apr 20, 2023 | 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. |
| CVE-2026-6180 | Hig | 0.53 | 8.1 | 0.00 | May 5, 2026 | A race condition exists in PaperCut MF when processing badge-swipe data from certain HP multifunction devices. Under specific network conditions involving dropped packets and out-of-order sequence counters, the server may incorrectly process fragmented data chunks. If a sequence reset notification fails to reach the server, the server may reject the initial data chunk while erroneously accepting subsequent chunks before a connection reset completes. This leads to the registration of a truncated badge ID string. While this typically results in an authentication failure, the vulnerability is compounded in environments utilizing custom badge-ID post-processing scripts. In such configurations, the truncated string may be transformed into a valid ID belonging to a different user, leading to unauthorized session establishment (Incorrect User Login) on the device. | |
| CVE-2026-6418 | Med | 0.32 | 4.9 | 0.00 | May 5, 2026 | An issue was discovered in the Shared Account Synchronization component of PaperCut MF (version 25.0.4). The application allows administrative users to configure a source path for account data synchronization. Due to a lack of proper path validation and sanitization, an authenticated user with administrative privileges can specify arbitrary file paths on the local file system. This allows for the enumeration of directory structures and the unauthorized reading of sensitive text-based configuration or system files. When the synchronization process is triggered, the application attempts to parse the contents of the specified file, subsequently exposing the data within the application's account management interface. This vulnerability could lead to the disclosure of sensitive system information or configuration details, depending on the permissions of the service account under which the application is running. | |
| CVE-2026-4794 | Med | 0.31 | 4.8 | 0.00 | Mar 31, 2026 | Multiple cross-site scripting (XSS) vulnerabilities in PaperCut NG/MF before 25.0.10 allow authenticated administrator users to inject arbitrary web script or HTML code via different UI fields. This could be used to compromise other admininistrator's sessions or perform unauthorized actions via the administrator's authenticated context (e.g. requires an active login session). | |
| CVE-2014-2658 | 0.00 | — | 0.00 | Apr 28, 2014 | Unspecified vulnerability in Papercut MF and NG before 14.1 (Build 26983) allows attacker to cause a denial of service via unknown vectors. | ||
| CVE-2014-2659 | 0.00 | — | 0.00 | Apr 22, 2014 | 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. |
