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.Show less

An issue was discovered in Open-Xchange OX App Suite before 7.8.2-rev8. Users can provide local file paths to the RSS reader; the response and error code give hints about whether the provided file exists or not. Attackers may discover specific system files or library versions on the middleware server to prepare further attacks.Show less

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.).Show less

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.Show less

An issue was discovered in Open-Xchange OX App Suite before 7.8.2-rev8. SVG files can be used as mp3 album covers. In case their XML structure contains script code, that code may get executed when calling the related cover URL. 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.).Show less

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.).Show less

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.).Show less

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.).Show less

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.).Show less

An issue was discovered in Open-Xchange OX App Suite before 7.8.2-rev5. JavaScript code can be used as part of ical attachments within scheduling E-Mails. This content, for example an appointment's location, will be presented to the user at the E-Mail App, depending on the invitation workflow. This code gets executed within the context of the user's current session. 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.).Show less

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).Show less

An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev11. Custom messages can be shown at the login screen to notify external users about issues with sharing links. This mechanism can be abused to inject arbitrary text messages. Users may get tricked to follow instructions injected by third parties as part of social engineering attacks.Show less

An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev8. References to external Open XML document type definitions (.dtd resources) can be placed within .docx and .xslx files. Those resources were requested when parsing certain parts of the generated document. As a result an attacker can track access to a manipulated document. Usage of a document may get tracked and information about internal infrastructure may get exposed.Show less
