Xerox Printer Vulnerabilities Enable Credential Capture

A popular small to midrange Xerox business printer contains two now-patched vulnerabilities in its firmware that allow attackers an opportunity to gain full access to an organization's Windows environment. The vulnerabilities affect firmware version 57.69.91 and earlier in Xerox VersaLink C7025 multifunction printers (MFPs). Both flaws enable what are known as pass-back attacks, a class of attacks that essentially allow a bad actor to capture user credentials by manipulating the MFPs' configuration. In certain situations, a malicious actor who successfully exploits the Xerox printer vulnerabilities would be able to capture credentials for Windows Active Directory, according to researchers at Rapid7 who discovered the flaws. "This means they could then move laterally within an organization's environment and compromise other critical Windows servers and file systems," Deral Heiland, principal security researcher, IoT, for Rapid7 wrote in a recent blog post. Xerox describes VersaLink C7025 as a multifunction printer featuring ConnectKey, a Xerox technology that allows customers to interact with the printers over the cloud and via mobile devices. Among other things, the technology includes security features that, according to Xerox, help prevent attacks, detect potentially malicious changes to the printer, and protect against unauthorized transmission of critical data. Xerox has positioned its VersaLink family of printers as ideal for small and medium-sized workgroups that print ...
