Linux Kernel up to 2.4.28/2.6.10 wan/sdla.c 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 was found in Linux Kernel up to 2.4.28/2.6.10 (Operating System) and classified as critical. This issue affects an unknown functionality of the file wan/sdla.c. 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:

wan/sdla.c in Linux kernel 2.6.x before 2.6.11 and 2.4.x before 2.4.29 does not require the CAP_SYS_RAWIO privilege for an SDLA firmware upgrade, with unknown impact and local attack vectors. NOTE: further investigation suggests that this issue requires root privileges to exploit, since it is protected by CAP_NET_ADMIN; thus it might not be a vulnerability, although capabilities provide finer distinctions between privilege levels.

The weakness was released 01/06/2006 (Website). It is possible to read the advisory at debian.org. The identification of this vulnerability is CVE-2006-0096 since 01/06/2006. The exploitation is known to be easy. Attacking locally is a requirement. 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 $5k-$25k at the moment (estimation calculated on 07/07/2021).

The vulnerability scanner Nessus provides a plugin with the ID 22559 (Debian DSA-1017-1 : kernel-source-2.6.8 - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian 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 Tenable (22559), SecurityFocus (BID 16304†), Secunia (SA18977†) and Vulnerability Center (SBV-15670†).
