CVE-2022-29281Network attack vector

Code execution via unchecked SMB hyperlinks

Published Apr 15, 2022 · Updated Aug 3, 2024

Improper file URI validation in Notable 1.9.0-beta.7 and earlier allows remote attackers to execute code through a crafted link. The link handler resolves a UNC path to an attacker-controlled SMB share and opens an executable from that share instead of rejecting the file URI. A user must click the link; resolution can also disclose NTLM credentials for an SMB relay attack, while successful launch runs code with the user's privileges.
