| CVE-2023-26453 | 1 Open-xchange | 1 Open-xchange Appsuite | 2024-11-21 | N/A | 7.6 HIGH |
| Requests to cache an image could be abused to include SQL queries that would be executed unchecked. Exploiting this vulnerability requires at least access to adjacent networks of the imageconverter service, which is not exposed to public networks by default. Arbitrary SQL statements could be executed in the context of the services database user account. API requests are now properly checked for valid content and attempts to circumvent this check are being logged as error. No publicly available exploits are known. | |||||
| CVE-2023-26452 | 1 Open-xchange | 1 Open-xchange Appsuite | 2024-11-21 | N/A | 7.6 HIGH |
| Requests to cache an image and return its metadata could be abused to include SQL queries that would be executed unchecked. Exploiting this vulnerability requires at least access to adjacent networks of the imageconverter service, which is not exposed to public networks by default. Arbitrary SQL statements could be executed in the context of the services database user account. API requests are now properly checked for valid content and attempts to circumvent this check are being logged as error. No publicly available exploits are known. | |||||
| CVE-2023-26451 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-11-21 | N/A | 7.5 HIGH |
| Functions with insufficient randomness were used to generate authorization tokens of the integrated oAuth Authorization Service. Authorization codes were predictable for third parties and could be used to intercept and take over the client authorization process. As a result, other users accounts could be compromised. The oAuth Authorization Service is not enabled by default. We have updated the implementation to use sources with sufficient randomness to generate authorization tokens. No publicly available exploits are known. | |||||
| CVE-2023-26450 | 1 Open-xchange | 1 Open-xchange Appsuite Frontend | 2024-11-21 | N/A | 5.4 MEDIUM |
| The "OX Count" web service did not specify a media-type when processing responses by external resources. 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 are now defining the accepted media-type to avoid code execution. No publicly available exploits are known. | |||||
| CVE-2023-26449 | 1 Open-xchange | 1 Open-xchange Appsuite Frontend | 2024-11-21 | N/A | 5.4 MEDIUM |
| The "OX Chat" web service did not specify a media-type when processing responses by external resources. 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 are now defining the accepted media-type to avoid code execution. No publicly available exploits are known. | |||||
| CVE-2023-26448 | 1 Open-xchange | 1 Open-xchange Appsuite Frontend | 2024-11-21 | N/A | 5.4 MEDIUM |
| 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. | |||||
| CVE-2023-26447 | 1 Open-xchange | 1 Open-xchange Appsuite Frontend | 2024-11-21 | N/A | 5.4 MEDIUM |
| 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. | |||||
| CVE-2023-26446 | 1 Open-xchange | 1 Open-xchange Appsuite Frontend | 2024-11-21 | N/A | 5.4 MEDIUM |
| 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. | |||||
| CVE-2023-26445 | 1 Open-xchange | 1 Open-xchange Appsuite Frontend | 2024-11-21 | N/A | 5.4 MEDIUM |
| 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. | |||||
| CVE-2023-26443 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-11-21 | N/A | 5.5 MEDIUM |
| Full-text autocomplete search allows user-provided SQL syntax to be injected to SQL statements. With existing sanitization in place, this can be abused to trigger benign SQL Exceptions but could potentially be escalated to a malicious SQL injection vulnerability. We now properly encode single quotes for SQL FULLTEXT queries. No publicly available exploits are known. | |||||
| CVE-2023-26442 | 1 Open-xchange | 1 Open-xchange Appsuite Office | 2024-11-21 | N/A | 3.2 LOW |
| In case Cacheservice was configured to use a sproxyd object-storage backend, it would follow HTTP redirects issued by that backend. An attacker with access to a local or restricted network with the capability to intercept and replay HTTP requests to sproxyd (or who is in control of the sproxyd service) could perform a server-side request-forgery attack and make Cacheservice connect to unexpected resources. We have disabled the ability to follow HTTP redirects when connecting to sproxyd resources. No publicly available exploits are known. | |||||
| CVE-2023-26441 | 1 Open-xchange | 1 Open-xchange Appsuite Office | 2024-11-21 | N/A | 5.7 MEDIUM |
| Cacheservice did not correctly check if relative cache object were pointing to the defined absolute location when accessing resources. An attacker with access to the database and a local or restricted network would be able to read arbitrary local file system resources that are accessible by the services system user account. We have improved path validation and make sure that any access is contained to the defined root directory. No publicly available exploits are known. | |||||
| CVE-2023-26440 | 1 Open-xchange | 1 Open-xchange Appsuite Office | 2024-11-21 | N/A | 7.1 HIGH |
| The cacheservice API could be abused to indirectly inject parameters with SQL syntax which was insufficiently sanitized and would later be executed when creating new cache groups. Attackers with access to a local or restricted network could perform arbitrary SQL queries. We have improved the input check for API calls and filter for potentially malicious content. No publicly available exploits are known. | |||||
| CVE-2023-26439 | 1 Open-xchange | 1 Open-xchange Appsuite Office | 2024-11-21 | N/A | 7.6 HIGH |
| The cacheservice API could be abused to inject parameters with SQL syntax which was insufficiently sanitized before getting executed as SQL statement. Attackers with access to a local or restricted network were able to perform arbitrary SQL queries, discovering other users cached data. We have improved the input check for API calls and filter for potentially malicious content. No publicly available exploits are known. | |||||
| CVE-2023-26438 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-11-21 | N/A | 4.3 MEDIUM |
| External service lookups for a number of protocols were vulnerable to a time-of-check/time-of-use (TOCTOU) weakness, involving the JDK DNS cache. Attackers that were timing DNS cache expiry correctly were able to inject configuration that would bypass existing network deny-lists. Attackers could exploit this weakness to discover the existence of restricted network infrastructure and service availability. Improvements were made to include deny-lists not only during the check of the provided connection data, but also during use. No publicly available exploits are known. | |||||
| CVE-2023-26436 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-11-21 | N/A | 7.1 HIGH |
| Attackers with access to the "documentconverterws" API were able to inject serialized Java objects, that were not properly checked during deserialization. Access to this API endpoint is restricted to local networks by default. Arbitrary code could be injected that is being executed when processing the request. A check has been introduced to restrict processing of legal and expected classes for this API. We now log a warning in case there are attempts to inject illegal classes. No publicly available exploits are known. | |||||
| CVE-2023-26435 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-11-21 | N/A | 5.0 MEDIUM |
| It was possible to call filesystem and network references using the local LibreOffice instance using manipulated ODT documents. Attackers could discover restricted network topology and services as well as including local files with read permissions of the open-xchange system user. This was limited to specific file-types, like images. We have improved existing content filters and validators to avoid including any local resources. No publicly available exploits are known. | |||||
| CVE-2023-26434 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-11-21 | N/A | 4.3 MEDIUM |
| When adding an external mail account, processing of POP3 "capabilities" responses are not limited to plausible sizes. Attacker with access to a rogue POP3 service could trigger requests that lead to excessive resource usage and eventually service unavailability. We now limit accepted POP3 server response to reasonable length/size. No publicly available exploits are known. | |||||
| CVE-2023-26433 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-11-21 | N/A | 4.3 MEDIUM |
| When adding an external mail account, processing of IMAP "capabilities" responses are not limited to plausible sizes. Attacker with access to a rogue IMAP service could trigger requests that lead to excessive resource usage and eventually service unavailability. We now limit accepted IMAP server response to reasonable length/size. No publicly available exploits are known. | |||||
| CVE-2023-26432 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-11-21 | N/A | 4.3 MEDIUM |
| When adding an external mail account, processing of SMTP "capabilities" responses are not limited to plausible sizes. Attacker with access to a rogue SMTP service could trigger requests that lead to excessive resource usage and eventually service unavailability. We now limit accepted SMTP server response to reasonable length/size. No publicly available exploits are known. | |||||
