Rewterz Threat Advisory – CVE-2018-0470 – Cisco IOS XE HTTP Packet Processing Denial of Service Vulnerability

September 27, 2018

A vulnerability has been reported in Cisco IOS XE, which can be exploited by malicious people to cause a DoS (Denial of Service).

 

 

IMPACT:  NORMAL

 

 

PUBLISH DATE:  27-09-2018

 

 

OVERVIEW

 

 

There’s an error within the web framework of Cisco IOS XE when processing HTTP packets. This error can be exploited by people with malicious intent to cause a buffer overflow via a specially crafted HTTP packet. This may cause Denial of Service. The vendor has released update for the vulnerability.

 

 

ANALYSIS

 

 

An unauthenticated remote attacker could cause a buffer overflow condition on an affected device by exploiting a vulnerability within the web framework of Cisco IOS XE software, resulting in a denial of service (DoS) condition.

 

 

When an attacker exploits the vulnerability, the affected software improperly parses malformed HTTP packets that are sent to an affected device for processing. Successful exploitation yields a buffer overflow resulting in a DOS condition.

 

However, successful exploitation requires the HTTP Server feature to be enabled.

 

 

AFFECTED PRODUCTS

 

 

Cisco IOS XE Denali 16.3.x

Cisco IOS XE 3.2.x

 

 

UPDATE

 

 

Please follow the vendor’s advisory on how to check the running version of your product, whether it’s affected or not, and the available updates.
