An issue was discovered in Open-Xchange Guard before 2.2.0-rev8. The "getprivkeybyid" API call is used to download a PGP Private Key for a specific user after providing authentication credentials. Clients provide the "id" and "cid" parameter to specify the current user by its user- and context-ID. The "auth" parameter contains a hashed password string which gets created by the client by asking the user to enter his or her OX Guard password. This parameter is used as single point of authentication when accessing PGP Private Keys. In case a user has set the same password as another user, it is possible to download another user's PGP Private Key by iterating the "id" and "cid" parameters. This kind of attack would also be able by brute-forcing login credentials, but since the "id" and "cid" parameters are sequential they are much easier to predict than a user's login name. At the same time, there are some obvious insecure standard passwords that are widely used. A attacker could send the hashed representation of typically weak passwords and randomly fetch Private Key of matching accounts. The attack can be executed by both internal users and "guests" which use the external mail reader.
Cross-site scripting (XSS) vulnerability in Open-Xchange OX Guard before 2.0.0-rev11 allows remote attackers to inject arbitrary web script or HTML via the uid field in a PGP public key, which is not properly handled in "Guard PGP Settings."
Cross-site scripting (XSS) vulnerability in unspecified dialogs for printing content in the Front End in Open-Xchange Server 6 and OX App Suite before 6.22.8-rev8, 6.22.9 before 6.22.9-rev15m, 7.x before 7.6.1-rev25, and 7.6.2 before 7.6.2-rev20 allows remote attackers to inject arbitrary web script or HTML via unknown vectors related to object properties.
Open-Xchange (OX) AppSuite and Server before 7.4.2-rev42, 7.6.0 before 7.6.0-rev36, and 7.6.1 before 7.6.1-rev14 does not properly handle directory permissions, which allows remote authenticated users to read files via unspecified vectors, related to the "folder identifier."
Cross-site scripting (XSS) vulnerability in the backend in Open-Xchange (OX) AppSuite before 7.4.2-rev40, 7.6.0 before 7.6.0-rev32, and 7.6.1 before 7.6.1-rev11 allows remote attackers to inject arbitrary web script or HTML via a crafted XHTML file with the application/xhtml+xml MIME type.
Cross-site scripting (XSS) vulnerability in Open-Xchange (OX) AppSuite before 7.2.2-rev31, 7.4.0 before 7.4.0-rev27, and 7.4.1 before 7.4.1-rev17 allows remote attackers to inject arbitrary web script or HTML via the header in an attached SVG file.
The Birthday widget in the backend in Open-Xchange (OX) AppSuite 7.2.x before 7.2.2-rev25 and 7.4.x before 7.4.0-rev14, in certain user-id sharing scenarios, does not properly construct a SQL statement for next-year birthdays, which allows remote authenticated users to obtain sensitive birthday, displayname, firstname, and surname information via a birthdays action to api/contacts, aka bug 29315.
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.
SQL injection vulnerability in Open-Xchange (OX) AppSuite before 7.4.2-rev36 and 7.6.x before 7.6.0-rev23 allows remote authenticated users to execute arbitrary SQL commands via a crafted jslob API call.
Cross-site scripting (XSS) vulnerability in the backend in Open-Xchange (OX) AppSuite before 7.4.2-rev33 and 7.6.x before 7.6.0-rev16 allows remote attackers to inject arbitrary web script or HTML via a folder publication name.
