Vnote

VNote is a note-taking platform. Prior to 4.3.0, VNote uses the assignment `preNode.innerHTML = p_metaData` in src/data/extra/web/js/markdownit.js to insert YAML frontmatter metadata into a pre element before the protectFromXss sanitization path runs. Opening an attacker-supplied Markdown note can therefore execute stored JavaScript in the file:// viewer context. Because QWebEngineSettings::LocalContentCanAccessRemoteUrls enables local content to access remote URLs, the script can read reachable local note files and transmit their contents to a remote server without further interaction after the note is opened. This issue is fixed in version 4.3.0.

A weakness has been identified in vnotex vnote up to 3.20.1. Impacted is an unknown function of the file /src/data/extra/web/js/markdownit.js of the component YAML Frontmatter. This manipulation of the argument p_metaData causes cross site scripting. The attack may be initiated remotely. The vendor was contacted early about this disclosure but did not respond in any way.

VNote is a note-taking platform. A Cross-Site Scripting (XSS) vulnerability has been identified in the Markdown rendering functionality of versions 3.18.1 and prior of the VNote note-taking application. This vulnerability allows the injection and execution of arbitrary JavaScript code through which remote code execution can be achieved. A patch for this issue is available at commit f1af78573a0ef51d6ef6a0bc4080cddc8f30a545. Other mitigation strategies include implementing rigorous input sanitization for all Markdown content and utilizing a secure Markdown parser that appropriately escapes or strips potentially dangerous content.

VNote is a note-taking platform. Prior to 3.18.1, a code execution vulnerability existed in VNote, which allowed an attacker to execute arbitrary programs on the victim's system. A crafted URI can be used in a note to perform this attack using file:/// as a link. For example, file:///C:/WINDOWS/system32/cmd.exe. This allows attackers to execute arbitrary programs by embedding a reference to a local executable file such as file:///C:/WINDOWS/system32/cmd.exe and file:///C:/WINDOWS/system32/calc.exe. This vulnerability can be exploited by creating and sharing specially crafted notes. An attacker could send a crafted note file and perform further attacks. This vulnerability is fixed in 3.18.1.

A vulnerability has been found in vnotex vnote up to 3.17.0 and classified as problematic. Affected by this vulnerability is an unknown functionality of the component Markdown File Handler. The manipulation with the input <xss onclick="alert(1)" style=display:block>Click here</xss> leads to cross site scripting. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-243139. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
