Published: 2011-05-02 10:20:04
CVE Author: NIST National Vulnerability Database

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

Impact:
Successful exploitation could allow remote attackers to execute arbitrary code within the context of the affected application or retrieve potentially sensitive information.

Affected Versions:
IBM Tivoli Directory Server 5.2 before 5.2.0.5-TIV-ITDS-IF0010, 6.0 before 6.0.0.67 (6.0.0.8-TIV-ITDS-IF0009), 6.1 before 6.1.0.40 (6.1.0.5-TIV-ITDS-IF0003), 6.2 before 6.2.0.16 (6.2.0.3-TIV-ITDS-IF0002), and 6.3 before 6.3.0.3

Technical Details:
The flaw is caused by a stack overflow error in the 'ibmslapd.exe' component when allocating a buffer via the 'ber_get_int()' function within 'libibmldap.dll' while handling LDAP CRAM-MD5 packets, which could be exploited by remote unauthenticated attackers to execute arbitrary code with SYSTEM privileges.

Recommendations:
Apply Vendor patches.

Summary:
The host is running IBM Tivoli Directory Server and is prone to remote code execution vulnerability.

Solution Type:
Vendor Patch

Detection Type:
Remote Vulnerability

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".
