Linux Kernel 2.2.0/2.4.0 sysctl Memory information disclosure

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 has been found in Linux Kernel 2.2.0/2.4.0 (Operating System) and classified as problematic. This vulnerability affects the function sysctl. The manipulation with the input value -1 leads to a information disclosure vulnerability (Memory). The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Linux kernel 2.4 and 2.2 allows local users to read kernel memory and possibly gain privileges via a negative argument to the sysctl call.

The weakness was disclosed 02/09/2001 by Chris Evans with Red Hat (Website). The advisory is shared for download at caldera.com. This vulnerability was named CVE-2001-0316. The exploitation appears to be easy. The attack needs to be approached locally. No form of authentication is required for a successful exploitation. Technical details and also a public exploit are known. The MITRE ATT&CK project declares the attack technique as T1592.

A public exploit has been developed in ANSI C and been published immediately after the advisory. It is possible to download the exploit at downloads.securityfocus.com. It is declared as proof-of-concept. As 0-day the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 38953 (Debian DSA-047-1 : kernel), 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 3 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (6079), Exploit-DB (20626), Tenable (38953), SecurityFocus (BID 2364†) and OSVDB (6017†). The entries VDB-16586, VDB-16587, VDB-16588 and VDB-16589 are pretty similar. Once again VulDB remains the best source for vulnerability data.
