Open-Xchange AppSuite

An issue was discovered in Open-Xchange OX App Suite before 7.8.2-rev8. Setting the user's name to JS code makes that code execute when selecting that user's "Templates" folder from OX Documents settings. This requires the folder to be shared to the victim. 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.).

OX Software GmbH OX App Suite 7.8.4 and earlier is affected by: Cross Site Scripting (XSS).

OX App Suite through 7.10.6 allows XSS via XHTML CDATA for a snippet, as demonstrated by the onerror attribute of an IMG element within an e-mail signature.

OX App Suite through 7.10.6 allows XSS via a deep link, as demonstrated by class="deep-link-app" for a /#!!&app=%2e./ URI.

OX App Suite through 7.10.6 allows XSS via HTML in text/plain e-mail messages.

OX App Suite through 7.10.6 allows XSS via script code within a contact that has an e-mail address but lacks a name.

OX App Suite through 7.10.6 allows XSS via a malicious capability to the metrics or help module, as demonstrated by a /#!!&app=io.ox/files&cap= URI.

User ID references at mentions in document comments were not correctly sanitized. Script code could be injected to a users session when working with a malicious document. Please deploy the provided updates and patch releases. User-defined content like comments and mentions are now filtered to avoid potentially malicious content. No publicly available exploits are known.

Presentations may contain references to images, which are user-controlled, and could include malicious script code that is being processed when editing a document. Script code embedded in malicious documents could be executed in the context of the user editing the document when performing certain actions, like copying content. The relevant attribute does now get encoded to avoid the possibility of executing script code. No publicly available exploits are known.

OX App Suite before 7.10.3-rev4 and 7.10.4 before 7.10.4-rev4 allows SSRF via a shared SVG document that is mishandled by the imageconverter component when the .png extension is used.

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.

OX App Suite through 7.10.3 allows SSRF because GET requests are sent to arbitrary domain names with an initial autoconfig. substring.

OX App Suite 7.8.4 and earlier allows SSRF.

OX App Suite 7.10.1 and 7.10.2 allows SSRF.

An issue was discovered in Open-Xchange OX App Suite before 7.8.2-rev8. API requests can be used to inject, generate and download executable files to the client ("Reflected File Download"). Malicious platform specific (e.g. Microsoft Windows) batch file can be created via a trusted domain without authentication that, if executed by the user, may lead to local code execution.

Cross-site scripting (XSS) vulnerability in the office-web component in Open-Xchange OX App Suite before 7.8.3-rev12 and 7.8.4 before 7.8.4-rev9 allows remote attackers to inject arbitrary web script or HTML via a crafted presentation file, related to copying content to the clipboard.

OX App Suite through 7.10.3 allows XSS.

OX App Suite 7.8.4 and earlier allows XSS. Internal reference: 58742 (Bug ID)

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.

OX App Suite 7.10.0 to 7.10.2 allows XSS.

OX App Suite 7.10.3 and earlier allows XSS via text/x-javascript, text/rdf, or a PDF document.

OX Software GmbH OX App Suite 7.8.4 and earlier is affected by: Cross Site Scripting (XSS).

OX Software GmbH OX App Suite 7.8.4 and earlier is affected by: Cross Site Scripting (XSS).

References to the "app loader" functionality could contain redirects to unexpected locations. Attackers could forge app references that bypass existing safeguards to inject malicious script code. Please deploy the provided updates and patch releases. References to apps are now controlled more strict to avoid relative references. No publicly available exploits are known.

Documents operations could be manipulated to contain invalid data types, possibly script code. Script code could be injected to an operation that would be executed for users that are actively collaborating on the same document. Operation data exchanged between collaborating parties does now get escaped to avoid code execution. No publicly available exploits are known.

Documents operations, in this case "drawing", could be manipulated to contain invalid data types, possibly script code. Script code could be injected to an operation that would be executed for users that are actively collaborating on the same document. Operation data exchanged between collaborating parties does now gets checked for validity to avoid code execution. No publicly available exploits are known.

OX App Suite through 8.2 allows XSS because BMFreehand10 and image/x-freehand are not blocked.

OX App Suite through 8.2 allows XSS via a certain complex hierarchy that forces use of Show Entire Message for a huge HTML e-mail message.

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.

OX App Suite 7.8.4 and earlier allows Information Exposure.

Open-Xchange GmbH OX App Suite 7.8.3 and earlier is affected by: Content Spoofing.

OX App Suite through 7.10.6 has Uncontrolled Resource Consumption via a large location request parameter to the redirect servlet.

OX App Suite through 7.10.6 has Uncontrolled Resource Consumption via a large request body containing a redirect URL to the deferrer servlet.

OX Software GmbH OX App Suite 7.8.4 and earlier is affected by: Information Exposure.

OX App Suite through 7.10.6 allows SSRF because the anti-SSRF protection mechanism only checks the first DNS AA or AAAA record.

OX App Suite through 7.10.3 allows SSRF via the the /ajax/messaging/message message API.

CRLF injection vulnerability in the redirect servlet in Open-Xchange AppSuite and Server before 6.22.0 rev15, 6.22.1 before rev17, 7.0.1 before rev6, and 7.0.2 before rev7 allows remote attackers to inject arbitrary HTTP headers and conduct open redirect attacks by leveraging improper sanitization of whitespace characters.

OX App Suite through 7.10.2 allows SSRF.

OX App Suite 7.10.3 and earlier allows SSRF, related to the mail account API and the /folder/list API.

Multiple race conditions in HtmlCleaner before 2.6, as used in Open-Xchange AppSuite 7.2.2 before rev13 and other products, allow remote authenticated users to read the private e-mail of other persons in opportunistic circumstances by leveraging lack of thread safety and performing a rapid series of (1) mail-sending or (2) draft-saving operations.
