KON up to 0.3.9b -Coding memory corruption

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.

Detailsinfo

A vulnerability was found in KON up to 0.3.9b and classified as critical. Affected by this issue is some unknown processing. The manipulation of the argument -Coding with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Buffer overflow in KON kon2 0.3.9b and earlier allows local users to execute arbitrary code via a long -Coding command line argument.

The bug was discovered 06/03/2003. The weakness was released 06/16/2003 by Janusz Niewiadomski (Website). The advisory is shared for download at redhat.com. This vulnerability is handled as CVE-2002-1155 since 09/26/2002. The exploitation is known to be easy. The attack needs to be approached locally. No form of authentication is required for exploitation. Technical details as well as a public exploit are known.

A public exploit has been developed in Perl. The exploit is available at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 14047 (Mandrake Linux Security Advisory : kon2 (MDKSA-2003:064)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 115021 (Red Hat kon2 Command Line Parsing Buffer Overflow Vulnerability).

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (12143), Exploit-DB (22719), Tenable (14047), SecurityFocus (BID 7790†) and OSVDB (2094†). Once again VulDB remains the best source for vulnerability data.
