ISS X-Force Database: ios-features-tcp-dos(49420): Cisco IOS multiple features TCP denial of service

Cisco IOS multiple features TCP denial of service

ios-features-tcp-dos (49420)

Medium Risk

Description:

Cisco IOS is vulnerable to a denial of service, caused by the improper handling of TCP packets when multiple features of Cisco IOS software are enabled. By sending a specially-crafted sequence of TCP packets to multiple TCP ports, a remote attacker could exploit this vulnerability to cause the device to reload resulting in a denial of service.

The following features are affected:

Airline Product Set (aka ALPS)
Serial Tunnel Code (aka STUN)
Block Serial Tunnel Code (aka BSTUN)
Native Client Interface Architecture (NCIA) support
Data-link switching (aka DLSw)
Remote Source-Route Bridging (RSRB)
Point to Point Tunneling Protocol (PPTP)
X.25 for Record Boundary Preservation (RBP)
X.25 over TCP (XOT)
X.25 Routing

*CVSS:

Base Score:	7.8
Access Vector:	Network
Access Complexity:	Low
Authentication:	None
Confidentiality Impact:	None
Integrity Impact:	None
Availability Impact:	Complete

Temporal Score:	5.8
Exploitability:	Unproven
Remediation Level:	Official-Fix
Report Confidence:	Confirmed

Consequences:

Denial of Service
