Vulnerabilities

YesWiki is a wiki system written in PHP. Prior to version 4.6.0, a stored and blind XSS vulnerability exists in the form title field. A malicious attacker can inject JavaScript without any authentication via a form title that is saved in the backend database. When any user visits that injected page, the JavaScript payload gets executed. This issue has been patched in version 4.6.0.

Cross Site Scripting vulnerability in YesWiki v.4.54 allows a remote attacker to execute arbitrary code via a crafted payload to the meta configuration robots field

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.

YesWiki is a wiki system written in PHP. The squelette parameter is vulnerable to path traversal attacks, enabling read access to arbitrary files on the server. This vulnerability is fixed in 4.5.2.

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.

YesWiki is a wiki system written in PHP. Prior to 4.4.5, the use of a weak cryptographic algorithm and a hard-coded salt to hash the password reset key allows it to be recovered and used to reset the password of any account. This issue is fixed in 4.4.5.
