Samba 3.0.2 <= 3.0.4 Buffer Overflow Vulnerability (CVE-2004-0600)

Published: 2021-09-24 10:59:30
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:C/I:C/A:C

Detection Type:
Remote Banner Unreliable

Solution Type:
Vendor Patch

Summary:
Potential Buffer Overrun in SWAT, Samba 3.0.2 - 3.0.4.

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The internal routine used by the Samba Web Administration Tool (SWAT v3.0.2 and later) to decode the base64 data during HTTP basic authentication is subject to a buffer overrun caused by an invalid base64 character. It is recommended that all Samba v3.0.2 or later installations running SWAT either (a) upgrade to v3.0.5, or (b) disable the swat administration service as a temporary workaround. This same code is used internally to decode the sambaMungedDial attribute value when using the ldapsam passdb backend. While we do not believe that the base64 decoding routines used by the ldapsam passdb backend can be exploited, sites using an LDAP directory service with Samba are strongly encouraged to verify that the DIT only allows write access to sambaSamAccount attributes by a sufficiently authorized user.

Affected Versions:
Samba versions 3.0.2 through 3.0.4.

Recommendations:
Update to version 3.0.5 or later.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
