| CVE-2023-26433 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-08-02 | 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-2023-26449 | 1 Open-xchange | 1 Open-xchange Appsuite Frontend | 2024-08-02 | 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-2023-26438 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-08-02 | 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-2023-26431 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-08-02 | 5 Medium |
| IPv4-mapped IPv6 addresses did not get recognized as "local" by the code and a connection attempt is made. Attackers with access to user accounts could use this to bypass existing deny-list functionality and trigger requests to restricted network infrastructure to gain insight about topology and running services. We now respect possible IPV4-mapped IPv6 addresses when checking if contained in a deny-list. No publicly available exploits are known. | ||||
| CVE-2023-26432 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-08-02 | 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. | ||||
| CVE-2023-26445 | 1 Open-xchange | 1 Open-xchange Appsuite Frontend | 2024-08-02 | 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-2023-26435 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-08-02 | 5 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-2023-26441 | 1 Open-xchange | 1 Open-xchange Appsuite Office | 2024-08-02 | 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-2023-26434 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-08-02 | 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-2023-26436 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-08-02 | 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-2023-26428 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-08-02 | 6.5 Medium |
| Attackers can successfully request arbitrary snippet IDs, including E-Mail signatures of other users within the same context. Signatures of other users could be read even though they are not explicitly shared. We improved permission handling when requesting snippets that are not explicitly shared with other users. No publicly available exploits are known. | ||||
| CVE-2023-26442 | 1 Open-xchange | 1 Open-xchange Appsuite Office | 2024-08-02 | 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-2023-26440 | 1 Open-xchange | 1 Open-xchange Appsuite Office | 2024-08-02 | 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-2023-26447 | 1 Open-xchange | 1 Open-xchange Appsuite Frontend | 2024-08-02 | 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-2023-26439 | 1 Open-xchange | 1 Open-xchange Appsuite Office | 2024-08-02 | 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-2023-26430 | 1 Open-xchange | 1 Open-xchange Appsuite Backend | 2024-08-02 | 3.5 Low |
| Attackers with access to user accounts can inject arbitrary control characters to SIEVE mail-filter rules. This could be abused to access SIEVE extension that are not allowed by App Suite or to inject rules which would break per-user filter processing, requiring manual cleanup of such rules. We have added sanitization to all mail-filter APIs to avoid forwardning control characters to subsystems. No publicly available exploits are known. | ||||
| CVE-2023-26446 | 1 Open-xchange | 1 Open-xchange Appsuite Frontend | 2024-08-02 | 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-2023-24599 | 1 Open-xchange | 1 Ox App Suite | 2024-08-02 | 4.3 Medium |
| OX App Suite before backend 7.10.6-rev37 allows authenticated users to change the appointments of arbitrary users via conflicting ID numbers, aka "ID confusion." | ||||
| CVE-2023-24600 | 1 Open-xchange | 1 Ox App Suite | 2024-08-02 | 4.3 Medium |
| OX App Suite before backend 7.10.6-rev37 allows authenticated users to bypass access controls (for reading contacts) via a move to their own address book. | ||||
| CVE-2023-24601 | 1 Open-xchange | 1 Ox App Suite | 2024-08-02 | 6.1 Medium |
| OX App Suite before frontend 7.10.6-rev24 allows XSS via a non-app deeplink such as the jslob API's registry sub-tree. | ||||
