Title
YesWiki: Unauthenticated SQL Injection
Summary
YesWiki is a wiki system written in PHP. Prior to version 4.6.4, an unauthenticated SQL injection in the Bazar form-import path (`FormManager::create()`) allows any unauthenticated visitor of a default YesWiki install to inject arbitrary SQL into an `INSERT` statement and read the full database, including `yeswiki_users.password` hashes. Version 4.6.4 fixes the issue.

Title
YesWiki has Unsafe eval() in Formula Calculator - Remote Code Execution (RCE) & Denial of Service (DoS)
Summary
YesWiki is a wiki system written in PHP. Prior to version 4.6.6, an unsafe execution vulnerability exists in the Bazar form field calculator (CalcField.php) of YesWiki. The application attempts to sanitize user-defined mathematical formulas using a complex recursive regular expression before passing them to the PHP eval() function. This implementation is inherently flawed: it is vulnerable to Regular Expression Denial of Service (ReDoS / Stack Overflow) which can crash the server, and it creates a high-risk architecture where any logic bypass directly results in arbitrary PHP code execution. Version 4.6.6 patches the issue.

Title
YesWiki Vulnerable to Unauthenticated Site Backup Creation and Download
Summary
YesWiki is a wiki system written in PHP. Prior to version 4.5.4, the request to commence a site backup can be performed and downloaded without authentication. The archives are created with a predictable filename, so a malicious user could create and download an archive without being authenticated. This could result in a malicious attacker making numerous requests to create archives and fill up the file system, or by downloading the archive which contains sensitive site information. This issue has been patched in version 4.5.4.

Title
YesWiki Vulnerable to Stored XSS in Comments
Summary
YesWiki is a wiki system written in PHP. Prior to version 4.5.4, a stored cross-site scripting (XSS) vulnerability was discovered in the application’s comments feature. This issue allows a malicious actor to inject JavaScript payloads that are stored and later executed in the browser of any user viewing the affected comment. The XSS occurs because the application fails to properly sanitize or encode user input submitted to the comments. Notably, the application sanitizes or does not allow execution of `<script>` tags, but does not account for payloads obfuscated using JavaScript block comments like `/* JavaScriptPayload */`. This issue has been patched in version 4.5.4.

Title
YesWiki vulnerable to authenticated arbitrary file deletion
Summary
YesWiki is a wiki system written in PHP. In versions up to and including 4.4.5, it is possible for any authenticated user, through the use of the filemanager to delete any file owned by the user running the FastCGI Process Manager (FPM) on the host without any limitation on the filesystem's scope. This vulnerability allows any authenticated user to arbitrarily remove content from the Wiki resulting in partial loss of data and defacement/deterioration of the website. In the context of a container installation of YesWiki without any modification, the `yeswiki` files (for example .php) are not owned by the same user (root) as the one running the FPM process (www-data). However in a standard installation, www-data may also be the owner of the PHP files, allowing a malicious user to completely cut the access to the wiki by deleting all important PHP files (like index.php or core files of YesWiki). Version 4.5.0 contains a patch for this issue.

This vulnerability allows any authenticated user to arbitrarily remove content from the Wiki resulting in partial loss of data and defacement/deterioration of the website. In the context of a container installation of YesWiki without any modification, the `yeswiki` files (for example .php) are not owned by the same user (root) as the one running the FPM process (www-data). However in a standard installation, www-data may also be the owner of the PHP files, allowing a malicious user to completely cut the access to the wiki by deleting all important PHP files (like index.php or core files of YesWiki).

Title
YesWiki Vulnerable to Authenticated Stored XSS
Summary
YesWiki is a wiki system written in PHP. In versions up to and including 4.4.5, it is possible for an authenticated user with rights to edit/create a page or comment to trigger a stored XSS which will be reflected on any page where the resource is loaded. The vulnerability makes use of the content edition feature and more specifically of the `{{attach}}` component allowing users to attach files/medias to a page. When a file is attached using the `{{attach}}` component, if the resource contained in the `file` attribute doesn't exist, then the server will generate a file upload button containing the filename. This vulnerability allows any malicious authenticated user that has the right to create a comment or edit a page to be able to steal accounts and therefore modify pages, comments, permissions, extract user data (emails), thus impacting the integrity, availability and confidentiality of a YesWiki instance. Version 4.5.0 contains a patch for the issue.

YesWiki: Unauthenticated SQL Injection
Summary
YesWiki is a wiki system written in PHP. Prior to version 4.6.4, an unauthenticated SQL injection in the Bazar form-import path (`FormManager::create()`) allows any unauthenticated visitor of a default YesWiki install to inject arbitrary SQL into an `INSERT` statement and read the full database, including `yeswiki_users.password` hashes. Version 4.6.4 fixes the issue.

Title
YesWiki has Unsafe eval() in Formula Calculator - Remote Code Execution (RCE) & Denial of Service (DoS)
Summary
YesWiki is a wiki system written in PHP. Prior to version 4.6.6, an unsafe execution vulnerability exists in the Bazar form field calculator (CalcField.php) of YesWiki. The application attempts to sanitize user-defined mathematical formulas using a complex recursive regular expression before passing them to the PHP eval() function. This implementation is inherently flawed: it is vulnerable to Regular Expression Denial of Service (ReDoS / Stack Overflow) which can crash the server, and it creates a high-risk architecture where any logic bypass directly results in arbitrary PHP code execution. Version 4.6.6 patches the issue.

Yeswiki Vulnerable to Unauthenticated Reflected Cross-site Scripting
Summary
YesWiki is a wiki system written in PHP. Prior to version 4.5.4, the `/?BazaR` endpoint and `idformulaire` parameter are vulnerable to cross-site scripting. An attacker can use a reflected cross-site scripting attack to steal cookies from an authenticated user by having them click on a malicious link. Stolen cookies allow the attacker to take over the user’s session. This vulnerability may also allow attackers to deface the website or embed malicious content. This issue has been patched in version 4.5.4.

Title
YesWiki Vulnerable to Unauthenticated Site Backup Creation and Download
Summary
YesWiki is a wiki system written in PHP. Prior to version 4.5.4, the request to commence a site backup can be performed and downloaded without authentication. The archives are created with a predictable filename, so a malicious user could create and download an archive without being authenticated. This could result in a malicious attacker making numerous requests to create archives and fill up the file system, or by downloading the archive which contains sensitive site information. This issue has been patched in version 4.5.4.

Title
YesWiki Vulnerable to Stored XSS in Comments
Summary
YesWiki is a wiki system written in PHP. Prior to version 4.5.4, a stored cross-site scripting (XSS) vulnerability was discovered in the application’s comments feature. This issue allows a malicious actor to inject JavaScript payloads that are stored and later executed in the browser of any user viewing the affected comment. The XSS occurs because the application fails to properly sanitize or encode user input submitted to the comments. Notably, the application sanitizes or does not allow execution of `<script>` tags, but does not account for payloads obfuscated using JavaScript block comments like `/* JavaScriptPayload */`. This issue has been patched in version 4.5.4.

The XSS occurs because the application fails to properly sanitize or encode user input submitted to the comments. Notably, the application sanitizes or does not allow execution of `\u003cscript\u003e` tags, but does not account for payloads obfuscated using JavaScript block comments like `/* JavaScriptPayload */`. This issue has been patched in version 4.5.4."

Title
YesWiki vulnerable to authenticated arbitrary file deletion
Summary
YesWiki is a wiki system written in PHP. In versions up to and including 4.4.5, it is possible for any authenticated user, through the use of the filemanager to delete any file owned by the user running the FastCGI Process Manager (FPM) on the host without any limitation on the filesystem's scope. This vulnerability allows any authenticated user to arbitrarily remove content from the Wiki resulting in partial loss of data and defacement/deterioration of the website. In the context of a container installation of YesWiki without any modification, the `yeswiki` files (for example .php) are not owned by the same user (root) as the one running the FPM process (www-data). However in a standard installation, www-data may also be the owner of the PHP files, allowing a malicious user to completely cut the access to the wiki by deleting all important PHP files (like index.php or core files of YesWiki). Version 4.5.0 contains a patch for this issue.

Title
YesWiki Vulnerable to Authenticated Stored XSS
Summary
YesWiki is a wiki system written in PHP. In versions up to and including 4.4.5, it is possible for an authenticated user with rights to edit/create a page or comment to trigger a stored XSS which will be reflected on any page where the resource is loaded. The vulnerability makes use of the content edition feature and more specifically of the `{{attach}}` component allowing users to attach files/medias to a page. When a file is attached using the `{{attach}}` component, if the resource contained in the `file` attribute doesn't exist, then the server will generate a file upload button containing the filename. This vulnerability allows any malicious authenticated user that has the right to create a comment or edit a page to be able to steal accounts and therefore modify pages, comments, permissions, extract user data (emails), thus impacting the integrity, availability and confidentiality of a YesWiki instance. Version 4.5.0 contains a patch for the issue.
