Vulnerabilities

An issue was discovered in Znuny before 7.1.4. Permissions are not checked properly when using the Generic Interface to update ticket metadata.

Znuny before LTS 6.5.1 through 6.5.10 and 7.0.1 through 7.0.16 allows DoS/ReDos via email. Parsing the content of emails where HTML code is copied from Microsoft Word could lead to high CPU usage and block the parsing process.

An issue was discovered in Znuny and Znuny LTS 6.0.31 through 6.5.7 and Znuny 7.0.1 through 7.0.16 where a logged-in user can upload a file (via a manipulated AJAX Request) to an arbitrary writable location by traversing paths. Arbitrary code can be executed if this location is publicly available through the web server.
