CVSS v3.1 |
| 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. |
| 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. |
| An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev11. The API to configure external mail accounts can be abused to map and access network components within the trust boundary of the operator. Users can inject arbitrary hosts and ports to API calls. Depending on the response type, content and latency, information about existence of hosts and services can be gathered. Attackers can get internal configuration information about the infrastructure of an operator to prepare subsequent attacks. |
| An issue was discovered in Open-Xchange OX Guard before 2.4.0-rev8. OX Guard uses an authentication token to identify and transfer guest users' credentials. The OX Guard API acts as a padding oracle by responding with different error codes depending on whether the provided token matches the encryption padding. In combination with AES-CBC, this allows attackers to guess the correct padding. Attackers may run brute-forcing attacks on the content of the guest authentication token and discover user credentials. For a practical attack vector, the guest users needs to have logged in, the content of the guest user's "OxReaderID" cookie and the value of the "auth" parameter needs to be known to the attacker. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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 7.8.1-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 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.). |
| Multiple cross-site scripting (XSS) vulnerabilities in Open-Xchange AppSuite before 7.2.2 allow remote authenticated users to inject arbitrary web script or HTML via (1) content with the text/xml MIME type or (2) the Status comment field of an appointment. |
| The (1) REST and (2) memcache interfaces in the Hazelcast cluster API in Open-Xchange AppSuite 7.0.x before 7.0.2-rev15 and 7.2.x before 7.2.2-rev16 do not require authentication, which allows remote attackers to obtain sensitive information or modify data via an API call. |
| Multiple cross-site scripting (XSS) vulnerabilities in Open-Xchange AppSuite and Server before 6.20.7 rev16, 6.22.0 before rev15, 6.22.1 before rev17, 7.0.1 before rev6, and 7.0.2 before rev7 allow remote attackers to inject arbitrary web script or HTML via (1) a javascript: URL, (2) malformed nested SCRIPT elements, (3) a mail signature, or (4) JavaScript code within an image file. |
| CRLF injection vulnerability in the redirect servlet in Open-Xchange AppSuite and Server before 6.22.0 rev15, 6.22.1 before rev17, 7.0.1 before rev6, and 7.0.2 before rev7 allows remote attackers to inject arbitrary HTTP headers and conduct open redirect attacks by leveraging improper sanitization of whitespace characters. |
| Multiple cross-site scripting (XSS) vulnerabilities in Open-Xchange AppSuite and Server before 6.20.7 rev18, 6.22.0 before rev16, 6.22.1 before rev19, 7.0.1 before rev7, 7.0.2 before rev11, and 7.2.0 before rev8 allow remote attackers to inject arbitrary web script or HTML via (1) embedded VBScript, (2) object/data Base64 content, (3) a Content-Type header, or (4) UTF-16 encoding, aka Bug IDs 25957, 26237, 26243, and 26244. |
| OXUpdater in Open-Xchange Server before 6.20.7 rev14, 6.22.0 before rev13, and 6.22.1 before rev14 does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof update servers and install arbitrary software via a crafted certificate. |
| Open-Xchange Server before 6.20.7 rev14, 6.22.0 before rev13, and 6.22.1 before rev14 uses weak permissions (group "other" readable) under opt/open-xchange/etc/, which allows local users to obtain sensitive information via standard filesystem operations. |
| Open-Xchange Server before 6.20.7 rev14, 6.22.0 before rev13, and 6.22.1 before rev14 uses the crypt and SHA-1 algorithms for password hashing, which makes it easier for context-dependent attackers to obtain cleartext passwords via a brute-force attack. |
