sysPass 3.0.1 through 3.2.11 contains an authentication bypass vulnerability that allows unauthenticated attackers to reinstall an already-installed instance by POSTing to the install/install handler, which never checks isInstalled(). Attackers can overwrite config.xml, point the application at an attacker-controlled database, create an administrator account, and plant serialized PublicLink gadget chains triggered via account/viewLink to execute commands.

sysPass's FileBackupService::doBackupFiles() in lib/SP/Services/Backup/FileBackupService.php around line 388 builds a tar shell command by string-concatenating the backup directory path $this->path directly into the command line ('tar czf ' . $backupFileApp . ' ' . BASEPATH . ' --exclude \"' . $this->path . '\" 2>&1') and passes the result to PHP's exec() with no application of escapeshellarg() and no validation of the path against a safe character set. The $this->path value is read from the sysPass configuration, which is persisted in the database and writable through the admin settings API and the admin UI. An administrator (or an attacker who has obtained an admin API token or admin session) can therefore store a backup path containing shell metacharacters and trigger a backup operation to execute arbitrary OS commands as the web server process user (typically www-data or apache). Because sysPass is a password manager whose sole purpose is to hold credentials for other systems, code execution as the web-server user permits reading sysPass's master password and encryption key from memory or configuration files, decrypting every stored credential in the database, exporting the entire password vault, pivoting to internal systems using the disclosed credentials, and installing persistent backdoors on the password-manager host.

sysPass through version 3.2.11 contains an OS command injection vulnerability that allows authenticated administrators to execute arbitrary commands as the web server process user by setting a malicious backup path and triggering a backup. The FileBackupService builds a tar shell command via string concatenation, inserting the admin-configurable siteBackupPath setting without escapeshellarg() or equivalent sanitization before passing it to exec(), causing injected commands to persist and execute on every subsequent backup trigger.

sysPass through version 3.2.11 contains a missing object-level authorization vulnerability in the JSON-RPC API that allows API token holders to enumerate account metadata, overwrite passwords, and delete accounts across the entire vault without per-account access control. Attackers can invoke AccountController methods such as viewAction, editAction, deleteAction, and editPassAction without AccountFilterUser checks to modify or delete accounts beyond the scope of their assigned token permissions.

sysPass through version 3.2.11 contains an insecure direct object reference vulnerability that allows any authenticated attacker to access account file attachments belonging to accounts they do not have ACL permissions for by exploiting missing authorization checks in AccountFileController. Attackers can supply arbitrary numeric file IDs through the download, view, delete, upload, and list actions to enumerate and manipulate any attachment in the vault, bypassing account-level access controls entirely.

A stored cross-site scripting (XSS) vulnerability in SysPass 3.2.x allows a malicious user with elevated privileges to execute arbitrary Javascript code by specifying a malicious XSS payload as a notification type or notification component.

The account file upload functionality in Syspass 3.2.x fails to properly handle special characters in filenames. This mismanagement leads to the disclosure of the web application s source code, exposing sensitive information such as the database password.

A host header injection vulnerability in SysPass 3.2x allows an attacker to load malicious JS files from an arbitrary domain which would be executed in the victim's browser.

A cross-site scripting (XSS) vulnerability in SysPass 3.2.x allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the name parameter at /Controllers/ClientController.php.

A vulnerability classified as problematic was found in nuxsmin sysPass up to 3.2.4. Affected by this vulnerability is an unknown functionality of the component URL Handler. The manipulation leads to cross site scripting. The attack can be launched remotely. Upgrading to version 3.2.5 is able to address this issue. The patch is named 4da4d031732ecca67519851fd0c34597dbb8ee55. It is recommended to upgrade the affected component. The associated identifier of this vulnerability is VDB-222319.

inc/SP/Html/Html.class.php in sysPass 2.1.9 allows remote attackers to bypass the XSS filter, as demonstrated by use of an "<svg/onload=" substring instead of an "<svg onload=" substring.

An issue was discovered in sysPass 2.x before 2.1, in which an algorithm was never sufficiently reviewed by cryptographers. The fact that inc/SP/Core/Crypt.class is using the MCRYPTRIJNDAEL256() function (the 256-bit block version of Rijndael, not AES) instead of MCRYPTRIJNDAEL128 (real AES) could help an attacker to create unknown havoc in the remote system.
