CVE-2020-24772 describes a critical vulnerability in Dreamacro Clash for Windows v0.11.4, allowing an attacker to embed a malicious iframe in a website. This iframe can force the Clash client to open a remote SMB share, triggering NTLM authentication. The NTLM request can then be relayed for code execution or captured for hash cracking, leading to a high-impact compromise. With a CVSS score of 8.8 (HIGH), this vulnerability has a low attack complexity and requires user interaction, but can result in complete loss of confidentiality, integrity, and availability. There is currently no public exploit code available (Metasploit, Nuclei, ExploitDB), and it is not listed on the CISA KEV catalog, indicating no known active exploitation.
