CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability classified as critical has been found in Apple Mac OS X Server up to 10.3.3 (Operating System). This affects an unknown code block of the component User Authentication. The manipulation of the argument PathName with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow in AppleFileServer for Mac OS X 10.3.3 and earlier allows remote attackers to execute arbitrary code via a LoginExt packet for a Cleartext Password User Authentication Method (UAM) request with a PathName argument that includes an AFPName type string that is longer than the associated length field.

The bug was discovered 03/26/2004. The weakness was published 05/03/2004 by Dave G. and Dino Dai Zovi with @stake, Inc. as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org. This vulnerability is uniquely identified as CVE-2004-0430 since 04/30/2004. The exploitability is told to be difficult. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

After 4 months, there has been an exploit disclosed. The exploit is shared for download at securiteam.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 38 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 12257 (Mac OS X < 10.3.4 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks and running in the context c.

It is possible to mitigate the problem by adding an authentication mechanism. A possible mitigation has been published 4 weeks after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 2545. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 3313.

The vulnerability is also documented in the databases at X-Force (16049), Tenable (12257) and Exploit-DB (391). Similar entries are available at 543, 682, 680 and 678.
