Wireshark up to 1.8.5 DTLS Dissector input validation

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 classified as critical has been found in Wireshark (Packet Analyzer Software). This affects an unknown code block of the component DTLS Dissector. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

The DTLS dissector in Wireshark 1.6.x before 1.6.14 and 1.8.x before 1.8.6 does not validate the fragment offset before invoking the reassembly state machine, which allows remote attackers to cause a denial of service (application crash) via a large offset value that triggers write access to an invalid memory location.

The weakness was shared 03/06/2013 by Laurent Butti as Wireshark 1.8.6 Release Notes as not defined release notes (Website). The advisory is shared at wireshark.org. The vendor cooperated in the coordination of the public release. This vulnerability is uniquely identified as CVE-2013-2488 since 03/06/2013. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available.

After even before and not, there has been an exploit disclosed. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 12 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 65557 (Debian DSA-2644-1 : wireshark - 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. The commercial vulnerability scanner Qualys is able to test this issue with plugin 166512 (OpenSuSE Security Update for wireshark (openSUSE-SU-2013:0494-1)).

Upgrading to version 1.8.6 eliminates this vulnerability. The upgrade is hosted for download at wireshark.org. The problem might be mitigated by replacing the product with tcpdump as an alternative. The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (82640), Tenable (65557), SecurityFocus (BID 58365†), OSVDB (91001†) and Secunia (SA52471†). The entries VDB-7931, VDB-7921, VDB-7922 and VDB-7925 are related to this item. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
