nfs-utils up to 1.0.6 rquota_server.c 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 nfs-utils up to 1.0.6. It has been rated as very critical. This issue affects an unknown code block of the file rquota_server.c of the component nfs-utils. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to 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). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

rquotad in nfs-utils (rquota_server.c) before 1.0.6-r6 on 64-bit architectures does not properly perform an integer conversion, which leads to a stack-based buffer overflow and allows remote attackers to execute arbitrary code via a crafted NFS request.

The bug was discovered 12/14/2004. The weakness was released 01/10/2005 by Arjan van de Ven as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org. The identification of this vulnerability is CVE-2004-0946 since 10/12/2004. 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 of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD at the moment (estimation calculated on 01/19/2025).

The vulnerability was handled as a non-public zero-day exploit for at least 6 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 16017 (RHEL 3 : nfs-utils (RHSA-2004:583)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Red Hat Local Security Checks and running in the context l.

Upgrading to version 1.0.6-r6 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 (18455), Tenable (16017), SecurityFocus (BID 11911†), OSVDB (12351†) and Secunia (SA13440†). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
