CVE-2010-4676

CVE-2010-4676

Description

Unspecified vulnerability on Cisco Adaptive Security Appliances (ASA) 5500 series devices with software before 8.2(3) allows remote authenticated users to cause a denial of service (device crash) via a high volume of IPsec traffic, aka Bug ID CSCsx52748.

AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

A high volume of IPsec traffic can crash Cisco ASA 5500 series devices running software before 8.2(3), requiring remote authenticated access.

Vulnerability

Cisco Adaptive Security Appliances (ASA) 5500 series devices running software versions prior to 8.2(3) contain an unspecified vulnerability in the handling of IPsec traffic. The issue is identified by Bug ID CSCsx52748. The exact code path is not disclosed, but the vulnerability is triggered by a high volume of IPsec packets.

Exploitation

An attacker must have remote authenticated access to the device. By sending a high volume of IPsec traffic, the attacker can trigger the vulnerability, leading to a device crash. No additional privileges or user interaction beyond authentication are required.

Impact

Successful exploitation results in a denial of service (DoS) condition, causing the ASA device to crash. This disrupts network security services and connectivity until the device is manually restarted or fails over.

Mitigation

Cisco released software version 8.2(3) to address this vulnerability [1]. Users should upgrade to this version or later. No workarounds are documented in the available references. The vulnerability is not listed on the CISA Known Exploited Vulnerabilities (KEV) catalog.
