Security Advisory-Heap Overflow Vulnerability in Huawei eSap Platform

  • SA No:Huawei-SA-20140616-01-eSap
  • Initial Release Date: Jun 16, 2014
  • Last Release Date: Sep 23, 2014

Huawei eSap software platform has four heap overflow vulnerabilities. Huawei products that have used this platform are affected. When receiving some special malformed packets, such devices access heap memory that is beyond the valid range and cause unexpected restart of the devices. If an attacker keeps sending such malformed packets, the devices will repeatedly restart, causing a denial of service (DoS) attack (Vulnerability ID: HWPSIRT-2014-0111).

This Vulnerability has been assigned Common Vulnerabilities and Exposures (CVE) ID: CVE-2014-4705.

Huawei has provided fixed versions.

Successful exploitation of the vulnerability can cause a DoS attack.

 

The vulnerability classification has been performed by using the CVSSv2 scoring system (http://www.first.org/cvss/).

Base Score: 7.8 (AV:N/AC:L/Au:N/C:N/I:N/A:C)

Temporal Score: 6.4 (E:F/RL:O/RC:C)

 

1. Prerequisite:

The attacker can remotely access the target devices.

2. Attacking procedure:

An attacker can trigger the vulnerability by remotely sending a special malformed packet. The validity of some length fields in the malformed packets is not checked. As a result, the devices receiving such malformed packets copy too much data into the heap memory and overwrite some other useful data, causing unexpected system restart.
