Detailsinfo

A vulnerability, which was classified as critical, was found in GNU Cfengine up to 2.1.7. This affects the function AuthenticationDialogue of the component Command Handler. The manipulation of the argument SAUTH with an unknown input leads to a heap-based overflow vulnerability. CWE is classifying the issue as CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Heap-based buffer overflow in the AuthenticationDialogue function in cfservd for Cfengine 2.0.0 to 2.1.7p1 allows remote attackers to execute arbitrary code via a long SAUTH command during RSA authentication.

The weakness was shared 08/09/2004 by CORE Security with CORE Security Technologies (Website). The advisory is shared at xforce.iss.net. This vulnerability is uniquely identified as CVE-2004-1701 since 02/21/2005. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

A public exploit has been developed in ANSI C. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 14314 (Cfengine AuthenticationDialogue() Function Remote Overflow), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gain a shell remotely and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 3309.

The vulnerability is also documented in the databases at X-Force (16935), Exploit-DB (24360), Tenable (14314), SecurityFocus (BID 10899†) and Secunia (SA12251†).
