CVE-2006-1017

High
Published: Translated: NVD NIST

Summary

The c-client library in PHP before 4.4.4 and 5.x before 5.1.5 does not check safe_mode or open_basedir settings. In applications that accept user-controlled input for the mailbox argument of the imap_open function, this allows remote attackers to access an IMAP stream data structure and perform unauthorized IMAP actions.

Risk Assessment

The organization is at risk of unauthorized access to IMAP servers, potentially leading to leakage of sensitive emails and compromise of communication integrity.

Recommendation

Immediately upgrade PHP to version 4.4.4 or later (for 4.x branch) and 5.1.5 or later (for 5.x branch). Additionally, in applications using imap_open, validate and restrict user input.
