Detailsinfo

A vulnerability classified as critical has been found in Goodtechsystems GoodTech SSH 6.4 (SSH Server Software). This affects an unknown functionality of the component Subsystem. 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. The summary by CVE is:

Stack-based buffer overflow in the SFTP subsystem in GoodTech SSH 6.4 allows remote authenticated users to execute arbitrary code via a long string to the (1) open (aka SSH_FXP_OPEN), (2) unlink, (3) opendir, and other unspecified parameters.

The weakness was presented 10/23/2008 by r0ut3r (Website). It is possible to read the advisory at securityfocus.com. This vulnerability is uniquely identified as CVE-2008-4726 since 10/23/2008. The exploitability is told to be easy. It is possible to initiate the attack remotely. The successful exploitation needs a authentication. Technical details are unknown but a public exploit is available.

A public exploit has been developed by r0ut3r in Perl and been published before and not just after the advisory. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (46038), Exploit-DB (6804), SecurityFocus (BID 31879†) and Secunia (SA32375†). Be aware that VulDB is the high quality source for vulnerability data.
