An issue was discovered in Open-Xchange OX Guard before 2.4.2-rev5. Script code which got injected to a mail with inline PGP signature gets executed when verifying the signature.

OX App Suite 7.10.1 and 7.10.2 allows XSS.

An issue was discovered in Open-Xchange OX App Suite before 7.8.2-rev8. Script code within hyperlinks at HTML E-Mails is not getting correctly sanitized when using base64 encoded "data" resources. This allows an attacker to provide hyperlinks that may execute script code instead of directing to a proper location. 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.).

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.).

Cross-site scripting (XSS) vulnerability in Open-Xchange (OX) AppSuite backend before 7.6.2-rev59, 7.8.0 before 7.8.0-rev38, 7.8.2 before 7.8.2-rev8; AppSuite frontend before 7.6.2-rev47, 7.8.0 before 7.8.0-rev30, and 7.8.2 before 7.8.2-rev8; Office Web before 7.6.2-rev16, 7.8.0 before 7.8.0-rev10, and 7.8.2 before 7.8.2-rev5; and Documentconverter-API before 7.8.2-rev5 allows remote attackers to inject arbitrary web script or HTML.

An issue was discovered in Open-Xchange OX App Suite before 7.8.2-rev8. Script code can be injected to contact names. When adding those contacts to a group, the script code gets executed in the context of the user which creates or changes the group by using autocomplete. In most cases this is a user with elevated permissions. 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.).

An issue was discovered in Open-Xchange OX App Suite before 7.8.2-rev8. SVG files can be used as profile pictures. In case their XML structure contains iframes and script code, that code may get executed when calling the related picture URL or viewing the related person's image within a browser. 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.).

An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev14. Adding images from external sources to HTML editors by drag&drop can potentially lead to script code execution in the context of the active user. To exploit this, a user needs to be tricked to use an image from a specially crafted website and add it to HTML editor areas of OX App Suite, for example E-Mail Compose or OX Text. This specific attack circumvents typical XSS filters and detection mechanisms since the code is not loaded from an external service but injected locally. 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.). To exploit this vulnerability, a attacker needs to convince a user to follow specific steps (social-engineering).

OX App Suite 7.10.5 allows XSS via an OX Chat room name.

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.

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.

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.

Open-Xchange GmbH OX App Suite 7.8.3 and earlier is affected by: Cross Site Scripting (XSS).

An issue was discovered in Open-Xchange OX App Suite before 7.8.2-rev8. Script code within SVG files is maintained when opening such files "in browser" based on our Mail or Drive app. In case of "a" tags, this may include link targets with base64 encoded "data" references. 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.).

Server-side request forgery (SSRF) vulnerability in the documentconverter component in Open-Xchange (OX) AppSuite before 7.4.2-rev10 and 7.6.x before 7.6.0-rev10 allows remote attackers to trigger requests to arbitrary servers and embed arbitrary images via a URL in an embedded image in a Text document, which is not properly handled by the image preview.

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.

chat in OX App Suite 7.10.5 has Improper Input Validation. A user can be redirected to a rogue OX Chat server via a development-related hook.

Frontend themes are defined by user-controllable jslob settings and could point to a malicious resource which gets processed during login. Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface and API. To exploit this an attacker would require temporary access to the users account or lure a user to a compromised account. We now sanitize the theme value and use a default fallback if no theme matches. No publicly available exploits are known.
