-----BEGIN PGP SIGNED MESSAGE----- Cisco Security Advisory: ATA-186 Password Disclosure Vulnerability Revision 1.0: INTERIM For Public Release 2002 May 23 16:00 GMT - ------------------------------------------------------------------------------- Contents ======== Summary Affected Products Details Impact Software Versions and Fixes Obtaining Fixed Software Workarounds Exploitation and Public Announcements Status of This Notice Distribution Revision History Cisco Security Procedures - ------------------------------------------------------------------------------- Summary ======= The Cisco ATA 186 Analog Telephone Adaptor is a handset-to-Ethernet adaptor that interfaces regular analog telephones with IP-based telephony networks. The adaptor turns traditional telephones into IP telephones. The ATA-186 is provided with a web-based configuration interface whose authentication is trivially circumvented. Using a crafted HTTP POST request the configuration of the device will be returned to the browser revealing configuration information such as passwords. This notice will be posted at http://www.cisco.com/warp/public/707/ata186-password-disclosure.shtml. Affected Products ================= The affected product is the Cisco ATA-186 analog telephone adapter. All releases before build 020514a are affected. No other Cisco product is currently known to be affected by this vulnerability. Details ======= CSCdx54579 A simple crafted HTTP POST request may cause the ATA-186 to display its configuration screen. Since the device does not hash its password, the actual password can be gleaned from this screen. The device can also be reconfigured in this way by constructing an HTTP POST with the appropriate parameters. Impact ====== By exploiting this vulnerability an attacker can compromise the integrity of the ATA-186. Software Versions and Fixes =========================== +---------------------------------------------------------------------------+ | Version Affected | Fixed Regular Release (available now) | | | Fix carries forward into all later versions | |------------------------+--------------------------------------------------| | Prior to build 020514a | ata186-v2-14-020514a-2.zip (H.323/SIP image) | | | ata186-v2-14-ms-020514a-2.zip (SCCP/MGCP image) | +---------------------------------------------------------------------------+ Obtaining Fixed Software ======================== Cisco is offering free software upgrades to address this vulnerability for all affected customers. Customers may only install and expect support for the feature sets they have purchased. Customers with service contracts should contact their regular update channels to obtain any software release containing the feature sets they have purchased. For most customers with service contracts, this means that upgrades should be obtained through the Software Center on Cisco's Worldwide Web site at http://www.cisco.com/. Customers whose Cisco products are provided or maintained through a prior or existing agreement with third-party support organizations such as Cisco Partners, authorized resellers, or service providers should contact that support organization for assistance with obtaining the free software upgrade(s). Customers who purchased directly from Cisco but who do not hold a Cisco service contract, and customers who purchase through third party vendors but are unsuccessful at obtaining fixed software through their point of sale, should obtain fixed software by contacting the Cisco Technical Assistance Center (TAC) using the contact information listed below. In these cases, customers are entitled to obtain an upgrade to a later version of the same release or as indicated by the applicable row in the Software Versions and Fixes table (noted above). Cisco TAC contacts are as follows: * +1 800 553 2447 (toll free from within North America) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac@cisco.com See http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml for additional TAC contact information, including special localized telephone numbers and instructions and e-mail addresses for use in various languages. Please have your product serial number available and give the URL of this notice as evidence of your entitlement to a free upgrade.
