Linksys bootp 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.

Detailsinfo

A vulnerability was found in Linksys (the affected version is unknown). It has been classified as problematic. This affects an unknown code of the component bootp. The manipulation with an unknown input leads to a information disclosure vulnerability (Memory). CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. The summary by CVE is:

DHCP on Linksys BEFSR11, BEFSR41, BEFSR81, and BEFSRU31 Cable/DSL Routers, firmware version 1.45.7, does not properly clear previously used buffer contents in a BOOTP reply packet, which allows remote attackers to obtain sensitive information.

The weakness was presented 05/22/2004 by Jon Hart (Website). It is possible to read the advisory at marc.info. This vulnerability is uniquely identified as CVE-2004-0580. The exploitability is told to be easy. The attack needs to be initiated within the local network. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available. The attack technique deployed by this issue is T1592 according to MITRE ATT&CK.

A public exploit has been developed in ANSI C and been published before and not just after the advisory. The exploit is shared for download at packetstormsecurity.nl. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k.

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 (16142), Exploit-DB (24115), SecurityFocus (BID 10329†), OSVDB (6325†) and Secunia (SA11606†). See VDB-658 for similar entry. Be aware that VulDB is the high quality source for vulnerability data.
