User-defined OXMF templates could be used to access a limited part of the internal OX App Suite Java API. The existing switch to disable the feature by default was not effective in this case. Unauthorized users could discover and modify application state, including objects related to other users and contexts. We now make sure that the switch to disable user-generated templates by default works as intended and will remove the feature in future generations of the product. No publicly available exploits are known.

The optional "LDAP contacts provider" could be abused by privileged users to inject LDAP filter strings that allow to access content outside of the intended hierarchy. Unauthorized users could break confidentiality of information in the directory and potentially cause high load on the directory server, leading to denial of service. Encoding has been added for user-provided fragments that are used when constructing the LDAP query. No publicly available exploits are known.

A component for parsing OXMF templates could be abused to execute arbitrary system commands that would be executed as the non-privileged runtime user. Users and attackers could run system commands with limited privilege to gain unauthorized access to confidential information and potentially violate integrity by modifying resources. The template engine has been reconfigured to deny execution of harmful commands on a system level. No publicly available exploits are known.

OX App Suite before backend 7.10.6-rev37 does not enforce 2FA for all endpoints, e.g., reading from a drive, reading contact data, and renaming tokens.

OX App Suite before backend 7.10.6-rev37 does not check HTTP header lengths when downloading, e.g., potentially allowing a crafted iCal feed to provide an unlimited amount of header data.

OX App Suite before backend 7.10.6-rev37 does not check size limits when downloading, e.g., potentially allowing a crafted iCal feed to provide an unlimited amount of data.

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.

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."

OX App Suite before backend 7.10.6-rev37 has an information leak in the handling of distribution lists, e.g., partial disclosure of the private contacts of another user.

OX App Suite through 8.2 allows XSS via an attachment or OX Drive content when a client uses the len or off parameter.

documentconverter in OX App Suite through 7.10.6, in a non-default configuration with ghostscript, allows OS Command Injection because file conversion may occur for an EPS document that is disguised as a PDF document.

OX App Suite through 7.10.6 allows SSRF because multipart/form-data boundaries are predictable, and this can lead to injection into internal Documentconverter API calls.

OX App Suite through 7.10.6 allows OS Command Injection via a serialized Java class to the Documentconverter API.

OX App Suite through 7.10.6 allows XSS via appHandler in a deep link in an e-mail message.

OX App Suite through 7.10.6 allows OS Command Injection via Documentconverter (e.g., through an email attachment).
