Vulnerabilities

An issue was discovered in PrinterOn Central Print Services (CPS) through 4.1.4. A user without valid credentials can bypass the authentication process, obtaining a valid session cookie with guest/pseudo-guest level privileges. This cookie can then be further used to perform other attacks.

An issue was discovered in PrinterOn Central Print Services (CPS) through 4.1.4. The core components that create and launch a print job do not perform complete verification of the session cookie that is supplied to them. As a result, an attacker with guest/pseudo-guest level permissions can bypass the session checks (that would otherwise logout a low-privileged user) by calling the core print job components directly via crafted HTTP GET and POST requests.

An XML external entity (XXE) vulnerability in PrinterOn version 4.1.4 and lower allows remote authenticated users to read arbitrary files or conduct server-side request forgery (SSRF) attacks via a crafted DTD in an XML request.

PrinterOn Enterprise 4.1.4 contains multiple Cross Site Request Forgery (CSRF) vulnerabilities in the Administration page. For example, an administrator, by following a link, can be tricked into making unwanted changes to a printer (Disable, Approve, etc).

PrinterOn Enterprise 4.1.4 suffers from multiple authenticated stored XSS vulnerabilities via the (1) "Machine Host Name" or "Server Serial Number" field in the clustering configuration, (2) "name" field in the Edit Group configuration, (3) "Rule Name" field in the Access Control configuration, (4) "Service Name" in the Service Configuration, or (5) First Name or Last Name field in the Edit Account configuration.

PrinterOn Enterprise 4.1.4 allows Arbitrary File Deletion.

PrinterOn Enterprise 4.1.3 stores the Active Directory bind credentials using base64 encoding, which allows local users to obtain credentials for a domain user by reading the cps_config.xml file.
