Detailsinfo

A vulnerability has been found in Vasion Print Virtual Appliance Host and Print Application (version now known) and classified as critical. Affected by this vulnerability is some unknown processing of the component Service. The manipulation with an unknown input leads to a link following vulnerability. The CWE definition for the vulnerability is CWE-59. The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. 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 22.0.843 and Application prior to 20.0.1923 (macOS/Linux client deployments) contain an arbitrary file write vulnerability via the response file handling. When tasks produce output the service writes response data into files under /opt/PrinterInstallerClient/tmp/responses/ reusing the requested filename. The service follows symbolic links in the responses directory and writes as the service user (typically root), allowing a local, unprivileged user to cause the service to overwrite or create arbitrary files on the filesystem as root. This can be used to modify configuration files, replace or inject binaries or drivers, and otherwise achieve local privilege escalation and full system compromise.

The weakness was presented by Pierre Barre. The advisory is shared at help.printerlogic.com. This vulnerability is known as CVE-2025-34191 since 04/15/2025. The exploitation appears to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available.
