SmartTV, dumb vuln: Philips hard-codes Miracast passwords

Best not browse smut on this TV


Video Demonstrating once again that consumer electronics companies don't understand security, ReVuln has turned up a hard-coded password in Philips “smart” televisions.

Shown off in the video below, the vulnerability is simplicity itself: the WiFi Miracast feature is switched on by default, has a fixed password (“Miracast”, for heaven's sake), no PIN, and doesn't request permission for new WiFi connections.

As ReVuln puts it, “anyone in the range of the TV WiFi adapter can easily connect to it and abuse of all the nice features offered by these SmartTV models”.

Their list of accessible features includes: “accessing the system and configuration files located on the TV; accessing the files located on the attached USB devices; transmitting video, audio and images to the TV; controlling the TV; and stealing the browser's cookies for accessing the websites used by the user” (this last one only applies to cookies of sites browsed using the TV).

The weak defaults, ReVuln's video demonstrates, exist in the most recent version of the Philips SmartTV firmware, QF2EU-0.173.46.0, installed on all 2013 models.

Last year, Samsung and LG were criticised for poor Internet-connected TV security. Internet of Things insecurities have also hit home automation systems and refrigerators. ®

  • DeadBolt ransomware takes another shot at QNAP storage
    Keep boxes updated and protected to avoid a NAS-ty shock

    QNAP is warning users about another wave of DeadBolt ransomware attacks against its network-attached storage (NAS) devices – and urged customers to update their devices' QTS or QuTS hero operating systems to the latest versions.

    The latest outbreak – detailed in a Friday advisory – is at least the fourth campaign by the DeadBolt gang against the vendor's users this year. According to QNAP officials, this particular run is encrypting files on NAS devices running outdated versions of Linux-based QTS 4.x, which presumably have some sort of exploitable weakness.

    The previous attacks occurred in January, March, and May.

  • How refactoring code in Safari's WebKit resurrected 'zombie' security bug
    Fixed in 2013, reinstated in 2016, exploited in the wild this year

    A security flaw in Apple's Safari web browser that was patched nine years ago was exploited in the wild again some months ago – a perfect example of a "zombie" vulnerability.

    That's a bug that's been patched, but for whatever reason can be abused all over again on up-to-date systems and devices – or a bug closely related to a patched one.

    In a write-up this month, Maddie Stone, a top researcher on Google's Project Zero team, shared details of a Safari vulnerability that folks realized in January this year was being exploited in the wild. This remote-code-execution flaw could be abused by a specially crafted website, for example, to run spyware on someone's device when viewed in their browser.

  • Wireless kit hit by supply chain woes in Q1, China lockdowns blamed
    Backlogs reportedly 10 to 15 times greater than they were pre-pandemic

    The Wireless LAN market was battered by a choppy supply chain in the first quarter of 2022 and lockdowns in China are compounding the problem, according to analysis by Dell'Oro Group.

    Many organizations have scheduled network upgrades, but supply is not able to keep pace with demand and backlogs are reportedly 10 to 15 times greater than they were pre-pandemic.

    Several manufacturers have cited components from second and third-tier suppliers as the cause of the bottleneck, Dell'Oro said, which means that the problem may not be a shortage of Wi-Fi silicon, but rather of secondary components that are nevertheless necessary to make a complete product.

  • Cisco warns of security holes in its security appliances
    Bugs potentially useful for rogue insiders, admin account hijackers

    Cisco has alerted customers to another four vulnerabilities in its products, including a high-severity flaw in its email and web security appliances. 

    The networking giant has issued a patch for that bug, tracked as CVE-2022-20664. The flaw is present in the web management interface of Cisco's Secure Email and Web Manager and Email Security Appliance in both the virtual and hardware appliances. Some earlier versions of both products, we note, have reached end of life, and so the manufacturer won't release fixes; it instead told customers to migrate to a newer version and dump the old.

    This bug received a 7.7 out of 10 CVSS severity score, and Cisco noted that its security team is not aware of any in-the-wild exploitation, so far. That said, given the speed of reverse engineering, that day is likely to come.

  • If you're using older, vulnerable Cisco small biz routers, throw them out
    Severe security flaw won't be fixed – as patches released this week for other bugs

    If you thought you were over the hump with Patch Tuesday then perhaps think again: Cisco has just released fixes for a bunch of flaws, two of which are not great.

    First on the priority list should be a critical vulnerability in its enterprise security appliances, and the second concerns another critical bug in some of its outdated small business routers that it's not going to fix. In other words, junk your kit or somehow mitigate the risk.

    Both of these received a CVSS score of 9.8 out of 10 in severity. The IT giant urged customers to patch affected security appliances ASAP if possible, and upgrade to newer hardware if you're still using an end-of-life, buggy router. We note that miscreants aren't actively exploiting either of these vulnerabilities — yet.

  • Halfords suffers a puncture in the customer details department
    I like driving in my car, hope my data's not gone far

    UK automobile service and parts seller Halfords has shared the details of its customers a little too freely, according to the findings of a security researcher.

    Like many, cyber security consultant Chris Hatton used Halfords to keep his car in tip-top condition, from tires through to the annual safety checks required for many UK cars.

    In January, Hatton replaced a tire on his car using a service from Halfords. It's a simple enough process – pick a tire online, select a date, then wait. A helpful confirmation email arrived with a link for order tracking. A curious soul, Hatton looked at what was happening behind the scenes when clicking the link and "noticed some API calls that seemed ripe for an IDOR" [Insecure Direct Object Reference].

  • CISA and friends raise alarm on critical flaws in industrial equipment, infrastructure
    Nearly 60 holes found affecting 'more than 30,000' machines worldwide

    Updated Fifty-six vulnerabilities – some deemed critical – have been found in industrial operational technology (OT) systems from ten global manufacturers including Honeywell, Ericsson, Motorola, and Siemens, putting more than 30,000 devices worldwide at risk, according to private security researchers. 

    Some of these vulnerabilities received CVSS severity scores as high as 9.8 out of 10. That is particularly bad, considering these devices are used in critical infrastructure across the oil and gas, chemical, nuclear, power generation and distribution, manufacturing, water treatment and distribution, mining and building and automation industries. 

    The most serious security flaws include remote code execution (RCE) and firmware vulnerabilities. If exploited, these holes could potentially allow miscreants to shut down electrical and water systems, disrupt the food supply, change the ratio of ingredients to result in toxic mixtures, and … OK, you get the idea.

  • Azure issues not adequately fixed for months, complain bug hunters
    Redmond kicks off Patch Tuesday with a months-old flaw fix

    Updated Two security vendors – Orca Security and Tenable – have accused Microsoft of unnecessarily putting customers' data and cloud environments at risk by taking far too long to fix critical vulnerabilities in Azure.

    In a blog published today, Orca Security researcher Tzah Pahima claimed it took Microsoft several months to fully resolve a security flaw in Azure's Synapse Analytics that he discovered in January. 

    And in a separate blog published on Monday, Tenable CEO Amit Yoran called out Redmond for its lack of response to – and transparency around – two other vulnerabilities that could be exploited by anyone using Azure Synapse.

  • AMD refreshes Ryzen Embedded line with R2000 series
    The target? Thin clients and industrial devices – with new SoC family running up to 4 independent displays

    Embedded World AMD is bringing to market a new generation of Ryzen chips for embedded apps promising more CPU cores, enhanced built-in graphics and expanded I/O connectivity to drive kit such as IoT devices and thin clients.

    Crucially, AMD plans to make the R2000 Series available for up to 10 years, providing OEM customers with a long-lifecycle support roadmap. This is an important aspect for components in embedded systems, which may be operating in situ for longer periods than the typical three to five-year lifecycle of corporate laptops and servers.

    The Ryzen Embedded R2000 Series is AMD's second-generation of mid-range system-on-chip (SoC) processors that combine CPU cores plus Radeon graphics, and target a range of embedded systems such as industrial and robotic hardware, machine vision, IoT and thin client devices. The first, R1000, came out in 2019.

  • For a few days earlier this year, rogue GitHub apps could have hijacked countless repos
    A bit of a near-hit for the software engineering world

    A GitHub bug could have been exploited earlier this year by connected third-party apps to hijack victims' source-code repositories.

    For almost a week in late February and early March, rogue applications could have generated scoped installation tokens with elevated permissions, allowing them to gain otherwise unauthorized write or administrative access to developers' repos. For example, if an app was granted read-only access to an organization or individual's code repo, the app could effortlessly escalate that to read-write access.

    This security blunder has since been addressed and before any miscreants abused the flaw to, for instance, alter code and steal secrets and credentials, according to Microsoft's GitHub, which assured The Register it's "committed to investigating reported security issues."
