ISS X-Force Database: ios-features-udp-dos(49419): Cisco IOS multiple features UDP denial of service

Cisco IOS multiple features UDP denial of service

ios-features-udp-dos (49419)

Medium Risk

Description:

Cisco IOS is vulnerable to a denial of service, caused by the improper handling of UDP packets when multiple features of Cisco IOS software are enabled. By sending specially-crafted UDP packets, a remote attacker could exploit this vulnerability to block the inbound interface resulting in a denial of service.

The following features are affected:

IP Service Level Agreements (SLAs) Responder
Session Initiation Protocol (SIP)
H.323 Annex E Call Signaling Transport
Media Gateway Control Protocol (MGCP)

*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

Remedy:

Refer to cisco-sa-20090325-udp for patch, upgrade or suggested workaround information. See References.
