CounterPath eyeBeam SIP Softphone - Denial of Service via Long SIP INVITE Header Field

Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 2 public exploits for CVE-2006-0359. PoCs published by ZwelL.

AI-analyzed exploit summary This exploit demonstrates a buffer overflow vulnerability in CounterPath eyeBeam by sending a maliciously crafted SIP INVITE request with an overly long 'From' header. The PoC sends multiple UDP packets to trigger a denial-of-service (DoS) condition, potentially leading to remote code execution.

Description

Buffer overflow in CounterPath eyeBeam SIP Softphone allows remote attackers to (1) cause a denial of service (device crash) via SIP INVITE commands with a long header field name sent during startup and (2) cause a denial of service (device hang or crash) via SIP INVITE commands with a long header field name sent during a call.
