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.

Cross-site scripting (XSS) vulnerability in the frontend in Open-Xchange (OX) AppSuite 6.22.3 before 6.22.3-rev5 and 6.22.4 before 6.22.4-rev12 allows remote attackers to inject arbitrary web script or HTML via the subject of an email. NOTE: the vulnerabilities related to the body of the email and the publication name were SPLIT from this CVE ID because they affect different sets of versions.

Cross-site scripting (XSS) vulnerability in Open-Xchange (OX) AppSuite 7.4.1 allows remote attackers to inject arbitrary web script or HTML via the title in a mail filter rule.

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.

CRLF injection vulnerability in Open-Xchange AppSuite before 7.2.2, when using AJP in certain conditions, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via the ajax/defer servlet.

OX App Suite through 7.10.5 allows XSS via JavaScript code in an anchor HTML comment within truncated e-mail, because there is a predictable UUID with HTML transformation results.

Cross-site scripting (XSS) vulnerability in webmail in Open-Xchange 0.8.1-6 and earlier, with "Inline HTML" enabled, allows remote attackers to inject arbitrary web script or HTML via e-mail attachments, which are rendered inline.

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.

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

OX App Suite before 7.10.6-rev30 allows XSS via an upsell trigger.

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.

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

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

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.

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.

User-defined script code could be stored for a upsell related shop URL. This code was not correctly sanitized when adding it to DOM. Attackers could lure victims to user accounts with malicious script code and make them execute it in the context of a trusted domain. We added sanitization for this content. No publicly available exploits are known.

Processing of CID references at E-Mail can be abused to inject malicious script code that passes the sanitization engine. Malicious script code could be injected to a users sessions when interacting with E-Mails. Please deploy the provided updates and patch releases. CID handing has been improved and resulting content is checked for malicious content. No publicly available exploits are known.

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.
