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 Carnegie Mellon University Cyrus IMAP Server 1.4. This affects an unknown functionality of the file imapparse.c. The manipulation with an unknown input leads to a integer coercion vulnerability. CWE is classifying the issue as CWE-192. Integer coercion refers to a set of flaws pertaining to the type casting, extension, or truncation of primitive data types. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Integer overflow in imapparse.c for Cyrus IMAP server 1.4 and 2.1.10 allows remote attackers to execute arbitrary code via a large length value that facilitates a buffer overflow attack, a different vulnerability than CVE-2002-1347.

The weakness was disclosed 06/14/2004 by Timo Sirainen as confirmed advisory (CERT.org). The advisory is shared at kb.cert.org. This vulnerability is uniquely identified as CVE-2002-1580 since 05/13/2004. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 15052 (Debian DSA-215-1 : cyrus-imapd - buffer overflow), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 1993.

The vulnerability is also documented in the databases at X-Force (10744) and Tenable (15052). The entries 23675, 23662, 23661 and 23660 are pretty similar.
