A flaw in Safari – that allows an attacker to spoof Attack.Phishing websites and trick Attack.Phishing victims into handing over their credentials – has yet to be patched Vulnerability-related.PatchVulnerability . A browser address bar spoofing flaw was found Vulnerability-related.DiscoverVulnerability by researchers this week in Safari – and Apple has yet issue Vulnerability-related.PatchVulnerability a patch for the flaw . Researcher Rafay Baloch on Monday disclosed Vulnerability-related.DiscoverVulnerability two proof-of-concepts revealing Vulnerability-related.DiscoverVulnerability how vulnerabilities in Edge browser 42.17134.1.0 and Safari iOS 11.3.1 could be abused to manipulate the browsers ’ address bars , tricking victims into thinking they are visiting a legitimate website . Baloch told Threatpost Wednesday that Apple has promised to fix Vulnerability-related.PatchVulnerability the flaw in its next security update for Safari . “ Apple has told [ me ] that the latest beta of iOS 12 also addresses Vulnerability-related.PatchVulnerability the issue , however they haven ’ t provided any dates , ” he said . Apple did not respond to multiple requests for comment from Threatpost . Microsoft for its part has fixed Vulnerability-related.PatchVulnerability the vulnerability Baloch found Vulnerability-related.DiscoverVulnerability in the Edge browser , ( CVE-2018-8383 ) in its August Patch Tuesday release . According to Microsoft ’ s vulnerability advisory released Vulnerability-related.PatchVulnerability August 14 , the spoofing flaw exists because Edge does not properly parse HTTP content . Both flaws stem from the Edge and Safari browsers allowing JavaScript to update the address bar while the page is still loading . This means that an attacker could request data from a non-existent port and , due to the delay induced by the setInterval function , trigger the address bar spoofing . The browser would then preserve the address bar and load the content from the spoofed page , Baloch said in his blog breaking down both vulnerabilities . From there , the attacker could spoof Attack.Phishing the website , using it to lure Attack.Phishing in victims and potentially gather credentials or spread malware . For instance , the attacker could send Attack.Phishing an email message containing the specially crafted URL to the user , convince the user to click it , and take them to the link which could gather their credentials or sensitive information . “ As per Google , Address bar is the only reliable indicator for ensuring the identity of the website , if the Address bar points to Facebook.com and the content is hosted on attacker ’ s website , there is no reason why someone would not fall for this , ” Baloch told Threatpost . In a video demonstration , Baloch showed how he could visit a link for the vulnerable browser on Edge ( http : //sh3ifu [ . ] com/bt/Edge-Spoof.html ) , which would take him to a site purporting to be Attack.Phishing Gmail login . However , while the URL points to a Gmail address , the content is hosted on sh3ifu.com , said Baloch . The Safari proof-of-concept is similar , except for one constraint where it does not allow users to type their information into the input boxes while the page is in a loading state . However , Bolach said he was able to circumvent this restriction by injecting a fake keyboard using Javascript – a common practice in banking sites . No other browsers – including Chrome or Firefox – were discovered Vulnerability-related.DiscoverVulnerability to have the flaw , said Baloch . Baloch is known for discovering Vulnerability-related.DiscoverVulnerability similar vulnerabilities in Chrome , Firefox and other major browsers in 2016 , which also allowed attackers to spoof URLs in the address bar . The vulnerabilities were disclosed Vulnerability-related.DiscoverVulnerability to both Microsoft and Apple and Baloch gave both a 90-day deadline before he went public Vulnerability-related.DiscoverVulnerability with the flaws . Due to the Safari browser bug being unpatched Vulnerability-related.PatchVulnerability , Baloch said he has not yet released a Proof of Concept : “ However considering there is a slight difference between the Edge browser POC and Safari , anyone with decent knowledge of Javascript can make it work on Safari , ” he told us .
