CSCsv38166 The server side of the Secure Copy (SCP) implementation in Cisco IOS 
software contains a vulnerability that could allow authenticated users with an 
attached command-line interface (CLI) view to transfer files to and from a Cisco 
IOS device that is configured to be an SCP server, regardless of what users are 
authorized to do, per the CLI view configuration.

This vulnerability could allow valid users to retrieve or write to any file on the device's file system, including the device's saved configuration and Cisco IOS image files, even if the CLI view attached to the user does not allow it. This configuration file may include passwords or other sensitive information.

The Cisco IOS SCP server is an optional service that is disabled by default. CLI views are a fundamental component of the Cisco IOS Role-Based CLI Access feature, which is also disabled by default. Devices that are not specifically configured to enable the Cisco IOS SCP server, or that are configured to use it but do not use role-based CLI access, are not affected by this vulnerability.

This vulnerability does not apply to the Cisco IOS SCP client feature.

Cisco has released free software updates that address this vulnerability.

There are no workarounds available for this vulnerability apart from disabling either the SCP server or the CLI view feature if these services are not required by administrators.

This advisory is posted at the following link:

http://www.cisco.com/warp/public/707/cisco-sa-20090325-scp.shtml.

CSCsu11522 A vulnerability exists in the Session Initiation Protocol (SIP) 
implementation in Cisco IOS software that can be exploited remotely to cause a 
reload of the Cisco IOS device.

Cisco has released free software updates that address this vulnerability. There are no workarounds available to mitigate the vulnerability apart from disabling SIP, if the Cisco IOS device does not need to run SIP for VoIP services. However, mitigation techniques are available to help limit exposure to the vulnerability.

This advisory is posted at the following link:

http://www.cisco.com/warp/public/707/cisco-sa-20090325-sip.shtml.

CSCsr29468 Cisco IOS software contains a vulnerability in multiple features that 
could allow an attacker to cause a denial of service (DoS) condition on the 
affected device. A sequence of specially crafted TCP packets can cause the 
vulnerable device to reload.

Cisco has released free software updates that address this vulnerability.

Several mitigation strategies are outlined in the workarounds section of this advisory.

This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20090325-tcp.shtml

CSCsq50366 Last digit getting truncated when prefix is set to its max value of 32.

Symptom    Last digit getting truncated when prefix is configured with a length of 32 under the dial-peer.

Conditions   When the prefix is configured with a length of 32 under the dial-peer only 31 digits are being sent across and the calls fails as there is no matching dial-peer at the other end. When the prefix is configured for 31 digits, then all the digits are sent correctly and the call is successful.

This is seen in the following call scenario:

1. Configure E1R2 ds0 groups between callgen and UUT:

2. Callgen calls into the UUT using ds0-group1.

3. The UUT has DID configured.

4. The UUT directs the call to ds0-group2 which is connected back to callgen.

5. Callgen has DID configured for the incoming call.

6. Callgen directs the call to ds0-group3 which is connected back to the UUT

7. The uut establishes a VoIP call leg back to callgen.

Workaround   None.

CSCsr68545 Error %DATACORRUPTION-1-DATAINCONSISTENCY when running ipsla with rtt.

Symptom    Error message occurs:

000302: Jul 24 13:00:13.575 CDT: %DATACORRUPTION-1-DATAINCONSISTENCY: copy error -Traceback= 0x410FD1A4 0x41119DB0 0x41138324 0x41DE5714

Conditions   IP SLA configured with RTT.

Workaround   None.

CSCsr27960 Traceback observed after configuring credential under sip-ua.

Symptom    Traceback observed when configuring credentials CLI under sip-ua.

Conditions   This happens when user configures credentials CLI with username length more than 32 characters.

Workaround   None.

CSCso58935 Caller ID still display Barge for point-to-point call between sccp 
share.

Symptom    Caller ID still display To Barge for point to point call between two sccp shared line phones after the other party drops out from cBarge conference.

Workaround   None.

CSCsr14658 CLI Cannot handle Double quotes.

Symptom    CME 4.3. IOS 12.4.15XZ SP Services. Under telephony-service the following url services was configured:

http://10.1.1.1 "My service"

Note the quotes. On the running config you see the above command without the quotes and everything works fine. When you type wr, then you again see the same command without the quotes. The issue is that, when you reload the router, the command is there, but it is not accepted and you have to type it again. Also, if you type url services http://10.1.1.1 My service, then you get an error of invalid input.

Conditions   Normal operation.

Workaround   Use one word and underscore instead of space.

CSCsq48167 CME DN description command may allow for open-ended quote delimination.

Symptom    The CME description command under the ephone-dn potentially allows for the description string to be saved to the router configuration without a trailing quote. This leaves an open-ended delimination in the configuration for the description string, and will cause the CME GUI to fail to load with an "unterminated string constant" error.

Conditions   There are two ways that the configuration can get a description with no closing quote:

1. Description is entered with quotes on both sides, and total string length is between 33 and 40 characters.

<i>Entering</i>

Router(config)#ephone-dn 1

Router(config-ephone-dn)#description "01234567890123456789012345678912345"

<i>Appears as</i>

ephone-dn 1

description "01234567890123456789012345678912

2. Description is entered with quotes only on beginning of string.

<i>Entering</i>

Router(config)#ephone-dn 1

Router(config-ephone-dn)#description "test

<i>Appears as</i>

ephone-dn 1

description "test

Workaround   Enter the description without any quotes via the CLI.
