FreeBSD/NetBSD/OpenBSD Shared Memory vm_map_find privileges management

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.

Summaryinfo

A vulnerability marked as problematic has been reported in FreeBSD, NetBSD and OpenBSD. Affected by this issue is the function vm_map_find of the component Shared Memory Handler. Performing a manipulation results in privileges management. This vulnerability is reported as CVE-2004-0114. Moreover, an exploit is present.

Detailsinfo

A vulnerability classified as problematic has been found in FreeBSD, NetBSD and OpenBSD (Operating System) (the affected version is unknown). This affects the function vm_map_find of the component Shared Memory Handler. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The shmat system call in the System V Shared Memory interface for FreeBSD 5.2 and earlier, NetBSD 1.3 and earlier, and OpenBSD 2.6 and earlier, does not properly decrement a shared memory segment s reference count when the vm_map_find function fails, which could allow local users to gain read or write access to a portion of kernel memory and gain privileges.

The bug was discovered 02/01/2004. The weakness was disclosed 02/05/2004 by Joost Pol (DiGiT) with Pine Digital Security (Website). It is possible to read the advisory at pine.nl. This vulnerability is uniquely identified as CVE-2004-0114. The exploitability is told to be easy. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details and a public exploit are known. The attack technique deployed by this issue is T1068 according to MITRE ATT&CK.

The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 4 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 12614 (FreeBSD : SA-04:02.shmat), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (15061), Exploit-DB (23655), Tenable (12614), SecurityFocus (BID 9586†) and OSVDB (3836†). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
