SMBleed: A New Critical Vulnerability Affects Windows SMB Protocol

Jun 09, 2020
Cybersecurity researchers today uncovered a new critical vulnerability affecting the Server Message Block (SMB) protocol that could allow attackers to leak kernel memory remotely, and when combined with a previously disclosed "wormable" bug, the flaw can be exploited to achieve remote code execution attacks. Dubbed " SMBleed " ( CVE-2020-1206 ) by cybersecurity firm ZecOps, the flaw resides in SMB's decompression function — the same function as with SMBGhost or EternalDarkness bug ( CVE-2020-0796 ), which came to light three months ago, potentially opening vulnerable Windows systems to malware attacks that can propagate across networks. The newly discovered vulnerability impacts Windows 10 versions 1903 and 1909, for which Microsoft today released security patches as part of its monthly Patch Tuesday updates for June . The development comes as the US Cybersecurity and Infrastructure Security Agency (CISA) issued an advisory last week warning Windows 10...

Brace yourselves for a possible 'second wave' of massive global cyber attack, as SMB ( Server Message Block) was not the only network protocol whose zero-day exploits created by NSA were exposed in the Shadow Brokers dump last month. Although Microsoft released patches for SMB flaws for supported versions in March and unsupported versions immediately after the outbreak of the WannaCry ransomware, the company ignored to patch other three NSA hacking tools, dubbed " EnglishmanDentist ," " EsteemAudit ," and " ExplodingCan ." It has been almost two weeks since WannaCry ransomware began to spread, which infected nearly 300,000 computers in more than 150 countries within just 72 hours, though now it has been slowed down. For those unaware, WannaCry exploited a Windows zero-day SMB bug that allowed remote hackers to hijack PCs running on unpatched Windows OS and then spread itself to other unpatched systems using its wormable capability. ...
