Open Xchange Appsuite

An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev11. The API to configure external mail accounts can be abused to map and access network components within the trust boundary of the operator. Users can inject arbitrary hosts and ports to API calls. Depending on the response type, content and latency, information about existence of hosts and services can be gathered. Attackers can get internal configuration information about the infrastructure of an operator to prepare subsequent attacks.Show less

An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev11. Script code can be embedded to RSS feeds using a URL notation. In case a user clicks the corresponding link at the RSS reader of App Suite, code gets executed at the context of the user. Malicious script code can be executed within a user's context. This can lead to session hijacking or triggering unwanted actions via the web interface (sending mail, deleting data etc.). The attacker needs to reside within the same context to make this attack work.Show less

An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev10. App Suite frontend offers to control whether a user wants to store cookies that exceed the session duration. This functionality is useful when logging in from clients with reduced privileges or shared environments. However the setting was incorrectly recognized and cookies were stored regardless of this setting when the login was performed using a non-interactive login method. In case the setting was enforced by middleware configuration or the user went through the interactive login page, the workflow was correct. Cookies with authentication information may become available to other users on shared environments. In case the user did not properly log out from the session, third parties with access to the same client can access a user's account.Show less

An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev11. The content sanitizer component has an issue with filtering malicious content in case invalid HTML code is provided. In such cases the filter will output a unsanitized representation of the content. Malicious script code can be executed within a user's context. This can lead to session hijacking or triggering unwanted actions via the web interface (sending mail, deleting data etc.). Attackers can use this issue for filter evasion to inject script code later on.Show less

An issue was discovered in Open-Xchange OX AppSuite before 7.8.0-rev27. The "defer" servlet offers to redirect a client to a specified URL. Since some checks were missing, arbitrary URLs could be provided as redirection target. Users can be tricked to follow a link to a trustworthy domain but end up at an unexpected service later on. This vulnerability can be used to prepare and enhance phishing attacks.Show less

An issue was discovered in Open-Xchange OX AppSuite before 7.8.0-rev27. The aria-label parameter of tiles at the Portal can be used to inject script code. Those labels use the name of the file (e.g. an image) which gets displayed at the portal application. Using script code at the file name leads to script execution. Malicious script code can be executed within a user's context. This can lead to session hijacking or triggering unwanted actions via the web interface (sending mail, deleting data etc.). Users actively need to add a file to the portal to enable this attack. In case of shared files however, a internal attacker may modify a previously embedded file to carry a malicious file name. Furthermore this vulnerability can be used to persistently execute code that got injected by a temporary script execution vulnerability.Show less

An issue was discovered in Open-Xchange Server 6 / OX AppSuite before 7.8.0-rev26. The "session" parameter for file-download requests can be used to inject script code that gets reflected through the subsequent status page. Malicious script code can be executed within a trusted domain's context. While no OX App Suite specific data can be manipulated, the vulnerability can be exploited without being authenticated and therefore used for social engineering attacks, stealing cookies or redirecting from trustworthy to malicious hosts.Show less

Cross-site scripting (XSS) vulnerability in unspecified dialogs for printing content in the Front End in Open-Xchange Server 6 and OX App Suite before 6.22.8-rev8, 6.22.9 before 6.22.9-rev15m, 7.x before 7.6.1-rev25, and 7.6.2 before 7.6.2-rev20 allows remote attackers to inject arbitrary web script or HTML via unknown vectors related to object properties.Show less

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."Show less

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.Show less

Cross-site scripting (XSS) vulnerability in Open-Xchange (OX) AppSuite before 7.2.2-rev31, 7.4.0 before 7.4.0-rev27, and 7.4.1 before 7.4.1-rev17 allows remote attackers to inject arbitrary web script or HTML via the header in an attached SVG file.Show less

The Birthday widget in the backend in Open-Xchange (OX) AppSuite 7.2.x before 7.2.2-rev25 and 7.4.x before 7.4.0-rev14, in certain user-id sharing scenarios, does not properly construct a SQL statement for next-year birthdays, which allows remote authenticated users to obtain sensitive birthday, displayname, firstname, and surname information via a birthdays action to api/contacts, aka bug 29315.Show less

Cross-site scripting (XSS) vulnerability in the frontend in Open-Xchange (OX) AppSuite before 7.4.2-rev33 and 7.6.x before 7.6.0-rev16 allows remote attackers to inject arbitrary web script or HTML via vectors related to unspecified fields in RSS feeds.Show less

Cross-site scripting (XSS) vulnerability in the backend in Open-Xchange (OX) AppSuite before 7.4.2-rev33 and 7.6.x before 7.6.0-rev16 allows remote attackers to inject arbitrary web script or HTML via a folder publication name.Show less

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.Show less

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.Show less

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.Show less

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'.Show less
