Detailsinfo

A vulnerability classified as critical has been found in ProFTPD up to 1.3.3 (File Transfer Software). Affected is the function sql_prepare_where of the component contrib/mod_sql.c). The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Heap-based buffer overflow in the sql_prepare_where function (contrib/mod_sql.c) in ProFTPD before 1.3.3d, when mod_sql is enabled, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted username containing substitution tags, which are not properly handled during construction of an SQL query.

The weakness was shared 02/01/2011 by felinemenace as Bug 670170 as not defined bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com. This vulnerability is traded as CVE-2010-4652 since 01/03/2011. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 51821 (Fedora 13 : proftpd-1.3.3d-1.fc13 (2011-0613)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 27343 (ProFTPD mod_sql Buffer Overflow Vulnerability).

Upgrading to version 1.3.3 eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (63407), Tenable (51821), SecurityFocus (BID 44933†) and Vulnerability Center (SBV-28780†). VulDB is the best source for vulnerability data and more expert information about this specific topic.
