Carnegie Mellon University Cyrus IMAP Server up to 2.2.4 stack-based overflow

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 Carnegie Mellon University Cyrus IMAP Server up to 2.2.4. It has been declared as very critical. Affected by this vulnerability is some unknown processing. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is 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). As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow in Cyrus IMAP Server 2.2.4 through 2.2.8, with the imapmagicplus option enabled, allows remote attackers to execute arbitrary code via a long (1) PROXY or (2) LOGIN command, a different vulnerability than CVE-2004-1015.

The bug was discovered 11/23/2004. The weakness was shared 01/10/2005 by Stefan Esser with eMatters (Website). It is possible to read the advisory at xforce.iss.net. This vulnerability is known as CVE-2004-1011 since 11/04/2004. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 06/05/2019).

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. The vulnerability was handled as a non-public zero-day exploit for at least 14 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 15923 (SUSE-SA:2004:043: cyrus-imapd), which helps to determine the existence of the flaw in a target environment.
