Vulnerabilidades

A type check was missing when handling fonts in PDF.js, which would allow arbitrary JavaScript execution in the PDF.js context. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11.

References to the "app loader" functionality could contain redirects to unexpected locations. Attackers could forge app references that bypass existing safeguards to inject malicious script code. Please deploy the provided updates and patch releases. References to apps are now controlled more strict to avoid relative…

Processing of user-defined mail search expressions is not limited. Availability of OX App Suite could be reduced due to high processing load. Please deploy the provided updates and patch releases. Processing time of mail search expressions now gets monitored, and the related request is terminated if a resource…

Processing time of drive search expressions now gets monitored, and the related request is terminated if a resource threshold is reached. Availability of OX App Suite could be reduced due to high processing load. Please deploy the provided updates and patch releases. Processing of user-defined drive search expressions…

Processing of user-defined DAV user-agent strings is not limited. Availability of OX App Suite could be reduced due to high processing load. Please deploy the provided updates and patch releases. Processing time of DAV user-agents now gets monitored, and the related request is terminated if a resource threshold is…

Processing of CID references at E-Mail can be abused to inject malicious script code that passes the sanitization engine. Malicious script code could be injected to a users sessions when interacting with E-Mails. Please deploy the provided updates and patch releases. CID handing has been improved and resulting content…

User ID references at mentions in document comments were not correctly sanitized. Script code could be injected to a users session when working with a malicious document. Please deploy the provided updates and patch releases. User-defined content like comments and mentions are now filtered to avoid potentially…

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…

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…

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…

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…

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…

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…

Requests to fetch image 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…

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…

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…

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 "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…

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…

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…

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…

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…

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…

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…

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…
