MWR Labs researchers recently disclosedVulnerability-related.DiscoverVulnerabilitytwo high-security vulnerabilities in LG G3 , G4 , and G5 mobile devices . The bugs include a Path Transversal flaw and an Arbitrary File Disclosure flaw , according to the respective security advisories . The Path Transversal flaw was caused by the application not validating that URL parameters did not contain potentially malicious characters and could allow an attacker on the same network as a user to make any media file or folder shareable without authentication or user interaction . The Arbitrary File Disclosure flaw was caused by the SmartShare.Cloud application launching an unauthenticated HTTP Server listening on all interfaces while connected to a WiFi network and could allow an attacker to retrieve any media file from the Cloud storage of the victim as long as they knew the file name . Users are encouraged to ensure their devices are updatedVulnerability-related.PatchVulnerabilityto the latest versions as Version 2.4.0 has mitigatedVulnerability-related.PatchVulnerabilitythe issues

A security lapse at content distribution network provider Cloudflare that resulted in customer data being leakedAttack.Databreachpublicly for several months was bad - but had the potential to be much worse . That 's Cloudflare 's initial postmortem conclusion after a twelve-day review of log data related to the breachAttack.Databreach. The review showed no evidence that attackers had exploitedVulnerability-related.DiscoverVulnerabilitythe flaw prior to it being discoveredVulnerability-related.DiscoverVulnerabilityand patchedVulnerability-related.PatchVulnerability, Cloudflare CEO and founder Matthew Prince said in a blog Wednesday . A `` vast majority '' of Cloudflare 's customers also did not appear to have had any of their data leakedAttack.Databreach. Cloudflare ’ s inspection of tens of thousands of pages that were leakedAttack.Databreachfrom its reverse-proxy servers and cached by search engines revealed a `` large number '' of instances of internal Cloudflare cookies and headers . But so far , according to Prince , there ’ s no evidence that passwords , credit card numbers , and other personal data were compromised as was initially feared . The Cloudflare security snafu stemmed from the manner in which a stream parser application that the company uses to modify content passing through its edge servers handled HTTP requests . The bug caused the parser to read memory not only from the HTML page that was being actually parsed , but also from adjacent memory that contained data in response to HTTP requests made by other customers . The flaw was triggered only when pages with certain specific attributes were requested through Cloudflare ’ s CDN . `` If you had accessed one of the pages that triggered the bug you would have seen what likely looked like random text at the end of the page , '' Prince said . A lot of the leaked data ended up getting cached by search engines and Web scrapers . A security researcher from Google ’ s Project Zero threat hunting team alertedVulnerability-related.DiscoverVulnerabilityCloudfare to the bug last month . The company claimed it fixedVulnerability-related.PatchVulnerabilitythe problem in a matter of hours after being notifiedVulnerability-related.DiscoverVulnerabilityof the problem . Some have compared the breach to Heartbleed and have even called it Cloudbleed . In his blog , Prince compared the threat posed by the bug to that posed by a stranger eavesdropping on a random conversation between two employees . Most of the time , the stranger would likely hear nothing of value , but occasionally might pick upAttack.Databreachsomething confidential . The same would have been true for a malicious attacker , who had somehow known aboutVulnerability-related.DiscoverVulnerabilitythe bug and exploitedVulnerability-related.DiscoverVulnerabilityit before Cloudflare ’ s fixVulnerability-related.PatchVulnerability, he said . The customers most at risk of having their data exposedAttack.Databreachwere those that sent the most requests through Cloudflare ’ s CDN . Cloudflare ’ s detailed postmortem and mea culpa evoked a mixed response from security experts . Ilia Kolochenko , CEO of Web security firm High-Tech Bridge praised Prince ’ s effort to be transparent about what went down . `` Even if we can not verify the accuracy of all the numbers inside – for the moment , I don ’ t have a valid reason to question either its content , or conclusion , '' Kolochenko says . In fact , until someone can come up with a credible rebuttal of Cloudflare ’ s internal investigation , it ’ s inappropriate to compare what happened at the company to Heartbleed . `` I ’ d say it ’ s inappropriate even to call this particular incident a 'Cloudbleed , ' '' he says . `` In the Heartbleed case , almost every company in the world , many software vendors including cybersecurity companies , were seriously impacted by the vulnerability . '' Heartbleed also resulted in multiple breachesAttack.Databreachand many organizations continue to be exposedAttack.Databreachto the threat . Neither of those situations applies to the Cloudflare security lapse . `` All avenues of Cloudflare ’ s vulnerability exploitation seems to be mitigatedVulnerability-related.PatchVulnerabilityby now , '' he says . But Kunal Anand , CTO of application security vendor Prevoty , says the details Cloudflare has shared are n't exactly reassuring . If no sensitive information like credit numbers and Social Security Numbers were leakedAttack.Databreachand the leaked dataset itself was relatively small , there is no reason why Cloudflare should n't share it with a third-party for an unbiased review , he says . `` CloudFlare needs to realize that HTTP headers , including cookies , contain sensitive information like session identifiers , authorization tokens and IP addresses , '' Anand says . `` All of these data points should count as private data . '' CloudFlare has been working with various search engines to purge their caches , but in the process , any evidence of the data that was leakedAttack.Databreachis being deleted as well . That makes it hard to quantify the scope of the data breachAttack.Databreachoutside of CloudFlare 's own logs . `` There 's a lot of speculation if nation-state sponsored engines will actually purge the data or copy it for further analysis , '' Anand says .
