Last modified
CVE-2020-24772 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. In Dreamacro Clash for Windows v0.11.4, an attacker could embed a malicious iframe in a website with a crafted URL that would launch the Clash Windows client and force it to open a remote SMB share. Windows will perform NTLM authentication when opening the SMB share and that request can be relayed (using a tool like responder) for code execution (or captured for hash cracking).. EPSS estimates a 0.63% chance of exploitation in the next 30 days.
