Detailsinfo

A vulnerability was found in Cisco Aironet (Wireless LAN Software) (version unknown). It has been classified as critical. This affects an unknown function of the component Initial Sequence Number Handler. The manipulation with an unknown input leads to a authentication spoofing vulnerability. CWE is classifying the issue as CWE-290. This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Cisco AP340 base station produces predictable TCP Initial Sequence Numbers (ISNs), which allows remote attackers to spoof or hijack TCP connections.

The weakness was presented 01/01/2001 (Website). The advisory is shared at cs.jhu.edu. This vulnerability is uniquely identified as CVE-2001-0163 since 03/06/2001. 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.

The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 10443 (TCP/IP Predictable ISN (Initial Sequence Number) Generation Weakness), which helps to determine the existence of the flaw in a target environment. It is assigned to the family General.

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 (20884), Exploit-DB (19522), Tenable (10443) and Vulnerability Center (SBV-26254†). See VDB-13695, VDB-16127, VDB-16230 and VDB-16231 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
