And just like other endpoints, attackers can leverage a compromised device to damage an organization's infrastructure and operations. 'It's easy to forget that modern MFPs are fully-functional computers that threat actors can compromise just like other workstations and endpoints. While the researchers determined that exploiting the vulnerabilities is difficult enough to prevent many low-skilled attackers from using them, experienced threat actors could make use of them in more targeted operations.ДЇurthermore, the researchers discovered the font parsing vulnerabilities are wormable, meaning attackers could create self-propagating malware that automatically compromises affected MFPs and then spreads to other vulnerable units on the same network. Attackers could also use compromised MFPs as a beachhead to penetrate further into an organization's network in pursuit of other objectives (such as stealing or changing other data, spreading ransomware, etc.) This includes not only documents that are printed, scanned, or faxed, but also information like passwords and login credentials that connect the device to the rest of the network.

The website would, automatically, remotely print a document containing a maliciously-crafted font on the vulnerable MFP, giving the attacker code execution rights on the device.ДЄn attacker with these code execution rights could silently steal any information ran (or cached) through the MFP. The most effective method would involve tricking a user from a targeted organization into visiting a malicious website, exposing the organization's vulnerable MFP to what's known as a cross-site printing attack. Security advisories published by HP list over 150 different products affected by the vulnerabilities. According to research published today by F-Secure, attackers can exploit the vulnerabilities to seize control of vulnerable devices, steal information, and further infiltrate networks to inflict other types of damage.ДЇ-Secure security consultants Timo Hirvonen and Alexander Bolshev discovered exposed physical access port vulnerabilities (CVE-2021-39237) and font parsing vulnerabilities (CVE-2021-39238) in HP's MFP M725z - part of HP's FutureSmart line of printers. has issued patches that fix security vulnerabilities cyber security provider F-Secure discovered in over 150 of their multifunction printer (MFP) products. This is our hobby,' Tuominen said.Helsinki, Finland - November 30, 2021: HP Inc. 'Some people play football, some people go sailing, some do photography. The researchers asked for no money from Assa for their work or discovery, saying they were only driven by the challenge. What is secure at a point of time, is not 20 years later,' Christophe Sut, an executive at Assa Abloy Hospitality, said in a phone interview. 'The challenge of the security business is that it is a moving target. The researchers say they have no evidence whether the vulnerabities they found have been put to work by criminals.ДЄssa Abloy stresses that its newer offerings are based on different technologies, including a system that allows hotel guests to open door locks with their smartphones. You cannot really know how secure the system is unless someone has really tried to break it.' 'I wouldn't be surprised if other electronic lock systems have similar vulnerabilities. 'These issues alone are not a problem, but once you combine those two things, it becomes exploitable,' Hirvonen said.

First it was purely a hobby, later a professional mission. Hearing of the theft at the conference, Tuominen and Hirvonen - then youthful computer guys in hacker-style black hoodies - asked themselves: Could one hack the locking system without leaving a trace?ДЇor years, the two worked off and on to solve the mystery of the plastic cards, which guests often neglect to return. The stolen laptop, which never turned up, belonged to a guest who had presented his research at a security conference.

The thief left no traces in the room or within the electric lock system, hotel personnel said. Clues date back to 2003 when a laptop disappeared from a computer security expert's room at a high-class hotel in Berlin.
