The package arrives as an ISO image, which means you'll need to create the bootable disc or USB key yourself. The exploits are not, incidentally, linked to an exploit Hirvonen and Bolshev used against an HP laserjet printer to get it to play Thunderstruck by AC/DC at the recent Pwn2Own event.F-Secure Rescue CD is a bootable environment for removing deeply-embedded malware on a PC.

HP was informed of the vulnerabilities at the end of April 2021 and has since worked extensively with F-Secure to patch them.

Although the attack is advanced, it can be mitigated with the basics: network segmentation, patch management and security hardening.”Īdditionally, there are a series of further steps defenders can take to secure their MFP estate, including limiting physical access, segregating MFPs on a firewalled VLAN of their own, using anti-tamper stickers to signal a device has been physically tampered with, following recommended supplier best practice for preventing unauthorised modification to security settings, and placing MFPs under video surveillance to record any physical access.

“There’s no need to panic, but they should assess their exposure, so they’re prepared for these attacks. “Large enterprises, companies working in critical sectors and other organisations facing highly skilled, well-resourced attackers need to take this seriously,” said Hirvonen. There is no evidence to suggest any of the vulnerabilities have been exploited in the wild, but, as is often the case when new bugs are disclosed, threat actors will likely be quick to weaponise them, so users of the affected devices, as per HP’s above-linked advisories, should patch them without delay, particularly if the organisation is considered more at risk of targeted attack by sophisticated actors. There’s no need to panic, but they should assess their exposure, so they’re prepared for these attacks”Īdditionally, CVE-2021-39238, the font parsing vulnerabilities, are wormable, which means an attacker could create a self-propagating malware that would automatically compromise at-risk printers and spread from them to other devices.

“Large enterprises, companies working in critical sectors and other organisations facing highly skilled, well-resourced attackers need to take this seriously. The font parsing issue isn’t the easiest to find or exploit, and anything requiring physical access poses logistical barriers for threat actors to overcome.” “However, these are not low-hanging fruits that would be obvious to many threat actors. Exploiting the font parser would only take a few seconds,” they warned. “A skilled attacker could successfully exploit the physical ports in a little over five minutes. Hirvonen and Bolshev believe that exploitation is difficult enough to prevent low-skilled actors from using them, whereas more experienced attackers could easily use them in targeted operations. In effect, this turns the printer into a beachhead on the network from where the attackers can spread out, establish persistence, and conduct deeper and more disruptive attacks up to data exfiltration and ransomware execution.

Hirvonen and Bolshev said the most effective method of exploiting these vulnerabilities would be to trick a user at the target organisation into visiting a malicious website and exposing their MFP to a cross-site printing attack whereby the website automatically remotely prints a document containing a maliciously crafted font on the vulnerable device, given the attacker code execution rights.įrom there, the attacker can steal any data being run, or that has been cached, on the printer, including not only printed, scanned or faxed documents, but also passwords and login credentials used to connect the printer to the network. “Experienced threat actors see unsecured devices as opportunities, so organisations that don’t prioritise securing their MFPs like other endpoints leave themselves exposed to attacks like the ones documented in our research.” And just like other endpoints, attackers can leverage a compromised device to damage an organisation’s infrastructure and operations,” said Hirvonen. “It’s easy to forget that modern MFPs are fully functional computers that threat actors can compromise just like other workstations and endpoints.

If exploited successfully, F-Secure consultants Timo Hirvonen and Alexander Bolshev said they could be used to gain full control of a target enterprise’s network. They are rated as being of high and critical severity respectively.

The vulnerabilities in question are tracked as CVE-2021-39237 and CVE-2021-39238, two access port vulnerabilities, which require physical access, and two font parsing vulnerabilities.
