The backend in Open-Xchange (OX) AppSuite 7.4.2 before 7.4.2-rev9 allows remote attackers to obtain sensitive information about user email addresses in opportunistic circumstances by leveraging a failure in e-mail auto configuration for external accounts.

Multiple cross-site scripting (XSS) vulnerabilities in Open-Xchange Server 6 and OX AppSuite before 7.4.2-rev43, 7.6.0-rev38, and 7.6.1-rev21.

Open-Xchange (OX) AppSuite and Server before 7.4.2-rev42, 7.6.0 before 7.6.0-rev36, and 7.6.1 before 7.6.1-rev14 does not properly handle directory permissions, which allows remote authenticated users to read files via unspecified vectors, related to the "folder identifier."

Cross-site scripting (XSS) vulnerability in the backend in Open-Xchange (OX) AppSuite before 7.4.2-rev40, 7.6.0 before 7.6.0-rev32, and 7.6.1 before 7.6.1-rev11 allows remote attackers to inject arbitrary web script or HTML via a crafted XHTML file with the application/xhtml+xml MIME type.

SQL injection vulnerability in Open-Xchange (OX) AppSuite before 7.4.2-rev36 and 7.6.x before 7.6.0-rev23 allows remote authenticated users to execute arbitrary SQL commands via a crafted jslob API call.

Cross-site scripting (XSS) vulnerability in Open-Xchange AppSuite 7.4.1 before 7.4.1-rev11 and 7.4.2 before 7.4.2-rev13 allows remote attackers to inject arbitrary web script or HTML via a Drive filename that is not properly handled during use of the composer to add an e-mail attachment.

The E-Mail autoconfiguration feature in Open-Xchange AppSuite before 7.2.2-rev20, 7.4.1 before 7.4.1-rev11, and 7.4.2 before 7.4.2-rev13 places a password in a GET request, which allows remote attackers to obtain sensitive information by reading (1) web-server access logs, (2) web-server Referer logs, or (3) the browser history.

The password recovery service in Open-Xchange AppSuite before 7.2.2-rev20, 7.4.1 before 7.4.1-rev11, and 7.4.2 before 7.4.2-rev13 makes an improper decision about the sensitivity of a string representing a previously used but currently invalid password, which allows remote attackers to obtain potentially useful password-pattern information by reading (1) a web-server access log, (2) a web-server Referer log, or (3) browser history that contains this string because of its presence in a GET request.

Cross-site scripting (XSS) vulnerability in the frontend in Open-Xchange (OX) AppSuite 7.4.1 before 7.4.1-rev10 and 7.4.2 before 7.4.2-rev8 allows remote attackers to inject arbitrary web script or HTML via the subject of an email, involving 'the aria "tags" for screenreaders at the top bar'.
