SiYuan is self-hosted, open source personal knowledge management software. SiYuan Note version 3.1.18 has an arbitrary file deletion vulnerability. The vulnerability exists in the `POST /api/history/getDocHistoryContent` endpoint. An attacker can craft a payload to exploit this vulnerability, resulting in the deletion of arbitrary files on the server. Commit d9887aeec1b27073bec66299a9a4181dc42969f3 fixes this vulnerability and is expected to be available in version 3.1.19.
SiYuan is a personal knowledge management system. Prior to version 3.1.16, SiYuan's `/api/template/renderSprig` endpoint is vulnerable to Server-Side Template Injection (SSTI) through the Sprig template engine. Although the engine has limitations, it allows attackers to access environment variables. Version 3.1.16 contains a patch for the issue.
SiYuan is a personal knowledge management system. Prior to version 3.1.16, the `/api/asset/upload` endpoint in Siyuan is vulnerable to both arbitrary file write to the host and stored cross-site scripting (via the file write). Version 3.1.16 contains a patch for the issue.
SiYuan is a personal knowledge management system. Prior to version 3.1.16, SiYuan's /api/export/exportResources endpoint is vulnerable to arbitary file read via path traversal. It is possible to manipulate the paths parameter to access and download arbitrary files from the host system by traversing the workspace directory structure. Version 3.1.16 contains a patch for the issue.
SiYuan is a personal knowledge management system. Prior to version 3.1.16, an arbitrary file read vulnerability exists in Siyuan's `/api/template/render` endpoint. The absence of proper validation on the path parameter allows attackers to access sensitive files on the host system. Version 3.1.16 contains a patch for the issue.
A SQL injection vulnerability was discovered in Siyuan 3.1.11 in /getHistoryItems.
A SQL injection vulnerability has been identified in Siyuan 3.1.11 via the ids array parameter in /batchGetBlockAttrs.
A SQL injection vulnerability has been identified in Siyuan 3.1.11 via the id parameter at /getAssetContent.
A SQL injection vulnerability has been identified in Siyuan 3.1.11 via the notebook parameter in /searchHistory.
A vulnerability has been found in SiYuan 3.1.0 and classified as problematic. Affected by this vulnerability is an unknown functionality of the file PDF.js of the component PDF Handler. The manipulation leads to cross site scripting. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-271993 was assigned to this vulnerability.
SiYuan version 3.0.3 allows executing arbitrary commands on the server. This is possible because the application is vulnerable to Server Side XSS.
An issue in symphony v.3.6.3 and before allows a remote attacker to execute arbitrary code via the log4j component.
Vditor is a browser-side Markdown editor. Versions prior to 3.8.7 are vulnerable to copy-paste cross-site scripting (XSS). For this particular type of XSS, the victim needs to be fooled into copying a malicious payload into the text editor. Version 3.8.7 contains a patch for this issue.
Cross-site Scripting (XSS) - Stored in GitHub repository vanessa219/vditor prior to 3.8.13.
Cross-site Scripting (XSS) - Stored in GitHub repository vanessa219/vditor prior to 3.8.12.
Cross-site Scripting (XSS) - Stored in GitHub repository vanessa219/vditor prior to 1.0.34.
b3log Symphony (aka Sym) before 3.6.0 has XSS via the HTTP User-Agent header.
b3log Wide before 1.6.0 allows three types of attacks to access arbitrary files. First, the attacker can write code in the editor, and compile and run it approximately three times to read an arbitrary file. Second, the attacker can create a symlink, and then place the symlink into a ZIP archive. An unzip operation leads to read access, and write access (depending on file permissions), to the symlink target. Third, the attacker can import a Git repository that contains a symlink, similarly leading to read and write access.
b3log Solo 2.9.3 has XSS in the Input page under the "Publish Articles" menu with an ID of "articleTags" stored in the "tag" JSON field, which allows remote attackers to inject arbitrary Web scripts or HTML via a carefully crafted site name in an admin-authenticated HTTP request.
In Symphony before 3.3.0, there is XSS in the Title under Post. The ID "articleTitle" of this is stored in the "articleTitle" JSON field, and executes a payload when accessing the /member/test/points URI, allowing remote attacks. Any Web script or HTML can be inserted by an admin-authenticated user via a crafted web site name.
An issue was discovered in b3log Symphony (aka Sym) before v3.4.7. XSS exists via the userIntro and userNickname fields to processor/SettingsProcessor.java.
In b3log Solo 2.9.3, XSS in the Input page under the Publish Articles menu, with an ID of linkAddress stored in the link JSON field, allows remote attackers to inject arbitrary Web scripts or HTML via a crafted site name provided by an administrator.
b3log Symphony (aka Sym) 2.6.0 allows remote attackers to upload and execute arbitrary JSP files via the name[] parameter to the /upload URI.
b3log Symphony (aka Sym) 2.2.0 has XSS in processor/AdminProcessor.java in the admin console, as demonstrated by a crafted X-Forwarded-For HTTP header that is mishandled during display of a client IP address in /admin/user/userid.
