Detailsinfo

A vulnerability has been found in Vasion Print Virtual Appliance Host and Print Application on Windows and classified as very critical. Affected by this vulnerability is an unknown function of the file defaults.ini. The manipulation with an unknown input leads to a hard-coded credentials vulnerability. The CWE definition for the vulnerability is CWE-798. The product contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 25.1.102 and Application prior to 25.1.1413 (Windows client deployments) contain a hardcoded private key for the PrinterLogic Certificate Authority (CA) and a hardcoded password in product configuration files. The Windows client ships the CA certificate and its associated private key (and other sensitive settings such as a configured password) directly in shipped configuration files (for example clientsettings.dat and defaults.ini). An attacker who obtains these files can impersonate the CA, sign arbitrary certificates trusted by the Windows client, intercept or decrypt TLS-protected communications, and otherwise perform man-in-the-middle or impersonation attacks against the product's network communications.
