OX App Suite before 7.10.3-rev32 and 7.10.4 before 7.10.4-rev18 allows XSS via a code snippet (user-generated content) when a sharing link is created and an App Loader relative URL is used.

Users were able to set an arbitrary "product name" for OX Guard. The chosen value was not sufficiently sanitized before processing it at the user interface, allowing for indirect cross-site scripting attacks. Accounts that were temporarily taken over could be configured to trigger persistent code execution, allowing an attacker to build a foothold. Sanitization is in place for product names now. No publicly available exploits are known.

Custom log-in and log-out locations are used-defined as jslob but were not checked to contain malicious protocol handlers. 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 jslob content for those locations to avoid redirects to malicious content. No publicly available exploits are known.

OX App Suite 7.10.1 and 7.10.2 allows XSS.

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 before frontend 7.10.6-rev24 allows XSS via data to the Tumblr portal widget, such as a post title.

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

OX App Suite through 7.10.4 allows XSS via use of the conversion API for a distributedFile.

The "upsell" widget at the portal page could be abused to inject arbitrary script code. Attackers that manage to lure users to a compromised account, or gain temporary access to a legitimate account, could inject script code to gain persistent code execution capabilities under a trusted domain. User input for this widget is now sanitized to avoid malicious content the be processed. No publicly available exploits are known.

The "upsell" widget for the portal allows to specify a product description. This description taken from a user-controllable jslob did not get escaped before being added to DOM. 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 jslob content. No publicly available exploits are known.

OX App Suite through 7.10.3 allows XSS.

The users clientID at "application passwords" was not sanitized or escaped before being added to DOM. 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 user-controllable clientID parameter. No publicly available exploits are known.

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 Guard before 2.4.2-rev5. Script code which got injected to a mail with inline PGP signature gets executed when verifying the signature. 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 Guard before 2.4.2-rev5. Script code can be provided as parameter to the OX Guard guest reader web application. This allows cross-site scripting attacks against arbitrary users since no prior authentication is needed. 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.) in case the user has an active session on the same domain already.

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 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. 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 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.).

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).

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.).

Upsell advertisement information of an account can be manipulated to execute script code in the context of the users browser session. To exploit this an attacker would require temporary access to a users account or an successful social engineering attack to lure users to maliciously configured accounts. Attackers could perform malicious API requests or extract information from the users account. Please deploy the provided updates and patch releases. Sanitization of user-defined upsell content has been improved. No publicly available exploits are known.

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.

OX App Suite before 7.10.6-rev20 allows XSS via upsell ads.

OX App Suite before 7.10.6-rev30 allows XSS via an activity tracking adapter defined by jslob.

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.

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.
