Exploitation Summary

EIP tracks 2 public exploits for CVE-2013-4074. PoCs published by j0sm1, Laurent Butti, j0sm1, including Metasploit module auxiliary/dos/wireshark/capwap.

AI-analyzed exploit summary This Metasploit auxiliary module exploits a denial-of-service vulnerability in Wireshark's CAPWAP dissector by sending a malformed UDP packet to port 5247. The packet contains a crafted flag byte (0x90) that triggers a crash in vulnerable versions of Wireshark.

Description

The dissect_capwap_data function in epan/dissectors/packet-capwap.c in the CAPWAP dissector in Wireshark 1.6.x before 1.6.16 and 1.8.x before 1.8.8 incorrectly uses a -1 data value to represent an error condition, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.
