Arbitrary File Disclosure via NTFS ADS in EFS Easy Address Book 1.2

IdentifiersCVE-2006-5715CWE-200

Easy File Sharing (EFS) Easy Address Book 1.2, when deployed on an NTFS file system, is vulnerable to arbitrary file disclosure. Remote attackers can append '::$DATA' to the end of an HTTP GET request to access the alternate data stream of files under the web root, thereby bypassing normal file access restrictions and reading file contents.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

An attacker can remotely read the contents of any file under the web root directory, potentially exposing sensitive information such as configuration files, credentials, or other data not intended for public access. This can lead to further compromise of the application or host.

Mitigation

If you can’t patch tonight, do this now.

Restrict access to the web root directory and ensure that sensitive files are not stored within it. Use file system permissions to prevent the web server process from accessing sensitive files. Consider using a file system other than NTFS if alternate data streams are not required, or implement web server rules to block requests containing '::$DATA'.

Remediation

Patch, then assume compromise.

Upgrade to a version of Easy Address Book that properly handles NTFS alternate data streams and does not allow access to them via HTTP requests. If no patch is available, consider migrating to a different address book solution.
