CyberRota Analysis

AI-Generated

Cyrus IMAP versions up to 3.12.2 are vulnerable to an ESEARCH cross-user content oracle, allowing authenticated users to enumerate folder names across different accounts. This vulnerability can lead to information disclosure by revealing user folder structures and message UIDs without granting access to the actual content. Organizations using affected versions of Cyrus IMAP should prioritize patching to mitigate potential information leakage risks.

Original NVD Description

An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. There is an ESEARCH cross-user content oracle. By using the ESEARCH command, an authenticated IMAP user could enumerate folder names under any account they could name. Search would return UIDs of messages matching the search, creating a content oracle (without allowing arbitrary reads of the target's content).
