FreeBSD/IRIX/Linux/NetBSD/OpenBSD/Tru64 FTPD glob 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, which was classified as very critical, has been found in FreeBSD, IRIX, Linux, NetBSD, OpenBSD and Tru64 (Operating System). This issue affects the function glob of the component FTPD. The manipulation 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. The summary by CVE is:

Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) g_opendir, (2) g_lstat, (3) g_stat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3.

The weakness was shared 06/18/2001 by John McDonald as confirmed advisory (CERT.org). The advisory is shared at cert.org. The identification of this vulnerability is CVE-2001-0247. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 06/24/2024). Due to its background and reception, this vulnerability has a historic impact.

A public exploit has been developed in ANSI C. The exploit is available at securityfocus.com. It is declared as functional. The vulnerability scanner Nessus provides a plugin with the ID 10648 (BSD Based FTP Server Multiple glob Function Remote Overflow), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FTP and running in the context r.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (6332), Exploit-DB (20731), Tenable (10648), SecurityFocus (BID 2548†) and Vulnerability Center (SBV-1407†). The entries VDB-16770 and VDB-16771 are related to this item. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
