Detailsinfo

A vulnerability classified as critical was found in Sun Solaris 2.5.1/2.6/7.0/8.0 (Operating System). Affected by this vulnerability is the function cfsd_calloc of the file cachefsd. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Heap-based buffer overflow in cfsd_calloc function of Solaris cachefsd allows remote attackers to execute arbitrary code via a request with a long directory and cache name.

The weakness was published 05/29/2002 as confirmed advisory (CERT.org). The advisory is shared at cert.org. This vulnerability is known as CVE-2002-0033. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details and also a public exploit are known.

A public exploit has been developed in ANSI C. It is possible to download the exploit at securityfocus.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 10951 (Solaris cachefsd Multiple Vulnerabilities (ESCROWUPGRADE)), 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 r. The commercial vulnerability scanner Qualys is able to test this issue with plugin 66050 (Solaris cachefsd Denial of Service Vulnerability).

Upgrading 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 1746.

The vulnerability is also documented in the databases at X-Force (8999), Tenable (10951), SecurityFocus (BID 4674†) and Vulnerability Center (SBV-1197†). Similar entries are available at VDB-17977 and VDB-17978. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
