CyberRota Analysis

AI-Generated

Mail content stored by users can be manipulated to execute dsync protocol commands when an administrator runs dsync with the stream protocol, potentially altering mailbox states and internal attributes during migration or replication. This vulnerability poses a risk of unauthorized modifications and dsync errors, particularly affecting environments that handle untrusted mail content. Administrators managing mail systems should prioritize applying updates to mitigate this risk.

Original NVD Description

Mail content stored by a user can be crafted so that it is interpreted as dsync protocol commands when an administrator later runs dsync with the stream protocol, for example during a migration. Injected commands can modify mailbox state on the destination during migration or replication, including internal mailbox attributes that a user should not be able to set directly. It can also cause dsync errors. Avoid running dsync with the stream protocol on mailboxes with untrusted content. Update to non-vulnerable version. No publicly available exploits are known.
