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 MCRYPT_RIJNDAEL_256() function (the 256-bit block version of Rijndael, not AES) instead of MCRYPT_RIJNDAEL_128 (real AES) could help an attacker to create unknown havoc in the remote system.

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.

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.

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.

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.

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.
