Detailsinfo

A vulnerability was found in Andrew Tridgell rsync 2.6 (File Transfer Software). It has been declared as critical. Affected by this vulnerability is an unknown part. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect integrity. The summary by CVE is:

rsync before 2.6.1 does not properly sanitize paths when running a read/write daemon without using chroot, which allows remote attackers to write files outside of the module s path.

The bug was discovered 04/30/2004. The weakness was presented 07/07/2004 (Website). The advisory is shared at redhat.com. This vulnerability is known as CVE-2004-0426 since 04/29/2004. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1006 for this issue.

The vulnerability was handled as a non-public zero-day exploit for at least 33 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 15336 (Debian DSA-499-2 : rsync - directory traversal), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 38303 (Rsync Sanitize_path Function Module Path Escaping Vulnerability).

Upgrading to version 2.6.1 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 2561. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 31478.

The vulnerability is also documented in the databases at X-Force (16014), Tenable (15336), SecurityFocus (BID 10247†), OSVDB (5731†) and Secunia (SA11514†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
