CVE-2023-26439open-xchangeopen-xchange_appsuite_office+1
EPSS score0.43%
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-2023-26434open-xchangeopen-xchange_appsuite_backend+1EPSS score1.15%
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-2023-26430open-xchangeopen-xchange_appsuite_backend+1EPSS score0.75%
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-2023-26431open-xchangeopen-xchange_appsuite_backend+1EPSS score0.84%
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-2023-26435open-xchangeopen-xchange_appsuite_backend+1EPSS score0.78%
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-2023-26438open-xchangeopen-xchange_appsuite_backend+1EPSS score0.60%
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-2023-26455open-xchangeopen-xchange_appsuite+1EPSS score0.19%
RMI was not requiring authentication when calling ChronosRMIService:setEventOrganizer. Attackers with local or adjacent network access could abuse the RMI service to modify calendar items using RMI. RMI access is restricted to localhost by default. The interface has been updated to require authenticated requests. No publicly available exploits are known.CVE-2023-26441open-xchangeopen-xchange_appsuite_office+1EPSS score0.40%
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-2023-29046open-xchangeopen-xchange_appsuite+1EPSS score0.48%
Connections to external data sources, like e-mail autoconfiguration, were not terminated in case they hit a timeout, instead those connections were logged. Some connections use user-controlled endpoints, which could be malicious and attempt to keep the connection open for an extended period of time. As a result users were able to trigger large amount of egress network connections, possibly exhausting network pool resources and lock up legitimate requests. A new mechanism has been introduced to cancel external connections that might access user-controlled endpoints. No publicly available exploits are known.CVE-2023-29047open-xchangeopen-xchange_appsuite+1EPSS score0.30%
Imageconverter API endpoints provided methods that were not sufficiently validating and sanitizing client input, allowing to inject arbitrary SQL statements. An attacker with access to the adjacent network and potentially API credentials, could read and modify database content which is accessible to the imageconverter SQL user account. None No publicly available exploits are known.CVE-2023-29043open-xchangeopen-xchange_appsuite+1EPSS score0.33%
Presentations may contain references to images, which are user-controlled, and could include malicious script code that is being processed when editing a document. Script code embedded in malicious documents could be executed in the context of the user editing the document when performing certain actions, like copying content. The relevant attribute does now get encoded to avoid the possibility of executing script code. No publicly available exploits are known.CVE-2023-29044open-xchangeopen-xchange_appsuite+1EPSS score0.38%
Documents operations could be manipulated to contain invalid data types, possibly script code. Script code could be injected to an operation that would be executed for users that are actively collaborating on the same document. Operation data exchanged between collaborating parties does now get escaped to avoid code execution. No publicly available exploits are known.CVE-2023-29045open-xchangeopen-xchange_appsuite+1EPSS score0.38%
Documents operations, in this case "drawing", could be manipulated to contain invalid data types, possibly script code. Script code could be injected to an operation that would be executed for users that are actively collaborating on the same document. Operation data exchanged between collaborating parties does now gets checked for validity to avoid code execution. No publicly available exploits are known.
