An attacker could exploit this vulnerability by sending API commands via HTTP to a particular URL without prior authentication,\u201d Cisco said in its [advisory](<https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170201-prime-home>). \u201cAn exploit could allow the attacker to perform any actions in Cisco Prime Home with administrator privileges.\u201d\n\nCisco said that versions 6.3, 6.4 and 6.5 are vulnerable and administrators should upgrade to version 6.5.0.1. The vendor added that it is not aware of any public attacks exploiting this vulnerability.\n\nAccording to a Cisco [product page](<http://www.cisco.com/c/en/us/products/cloud-systems-management/prime-home/index.html>), Cisco Prime home includes a number of customer support tools and views into all connected devices in a service provider\u2019s subscriber\u2019s home at scale. This is an attractive vantage point for an attacker looking to manipulate devices on a home network; admin privileges would give an attacker access to devices and allow them to alter configurations, redirect traffic and more.\n\nThe tool communicates over the TR-069 suite of protocols; TR-069 is a [Broadband Forum spec](<https://www.broadband-forum.org/technical/download/TR-069.pdf>) that defines how customer premise equipment communicates with an auto-configuration server such as Cisco Prime Home. A 2014 DEFCON talk by Check Point Software Technologies researcher Shahar Tal described how TR-069 could be abused to [attack residential routers and Internet gateways](<https://www.defcon.org/images/defcon-22/dc-22-presentations/Tal/DEFCON-22-Shahar-TaI-I-hunt-TR-069-admins-UPDATED.pdf>).\n\nThis is the second time since November that Cisco has had to roll out patches for Prime Home, when [a similar authentication bypass flaw](<https://threatpost.com/cisco-patches-critical-bugs-in-900-series-routers-prime-home-server/121765/>), CVE-2016-6452, was patched; the bug was found in the same web GUI and granted admin privileges to an attacker as well.\n", "reporter": "Michael Mimoso", "published": "2017-02-03T10:23:05", "type": "threatpost", "title": "Cisco Patches Authentication Bypass in Cisco Prime Home", "enchantments": {"score": {"modified": "2018-10-06T22:54:08", "vector": "NONE", "value": 7.5}}, "bulletinFamily": "info", "cvelist": ["CVE-2016-6452"], "_object_type": "robots.models.threatpost.ThreatpostBulletin", "modified": "2017-02-03T15:23:05", "id": "THREATPOST:DBD315EFDCE81B10FB27BB5B4FDBDE0A", "href": "https://threatpost.com/cisco-patches-authentication-bypass-in-cisco-prime-home/123551/", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2018-10-06T22:54:30", "_object_types": ["robots.models.base.Bulletin", "robots.models.threatpost.ThreatpostBulletin"], "references": ["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20161102-tl1", "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20161102-cph", "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20161102-cms", "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20161102-cms1", "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20161102-tp", "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20161026-esawsa3"], "description": "Cisco Systems has issued two critical advisories addressing flaws in a variety of enterprise-class products ranging from its 900 Series Routers to its Cisco Prime Home server and cloud-based network management platform.\n\nService providers running Cisco ASR 900 Series routers are being warned that a vulnerability in the Transaction Language 1 (TL1) code of the router could allow an unauthenticated, remote attacker to cause a reload of, or remotely execute code on, the affected system, according to the advisory.\n\nCisco said software updates are available to patch the flaw ([CVE-2016-6441](<https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20161102-tl1>)) and that workarounds are also available that address the security vulnerability.\n\nAn additional critical authentication bypass vulnerability was identified in the web-based graphical user interface of its Cisco Prime Home. \u201c(The) vulnerability could allow an unauthenticated, remote attacker to bypass authentication. The attacker could be granted full administrator privileges,\u201d Cisco warned.\n\nThe flaw ([CVE-2016-6452](<https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20161102-cph>)) is tied to a URL processing error in the system that could allow an attacker to send a crafted HTTP request to a specific URL. That creates conditions for an attacker to \u201cobtain a valid session identifier for an arbitrary user, which would allow the attacker to perform any actions in Cisco Prime Home for which that user is authorized\u2014including users with administrator privileges,\u201d Cisco wrote.\n\nA software patch is available to address this vulnerability, but no workaround is available.\n\nIn addition to the aforementioned, Cisco warned of two additional vulnerabilities rated as high. Both vulnerabilities are tied to its Cisco Meeting Server product lines. One of the flaws ([CVE-2016-6447](<https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20161102-cms>)) is a buffer underflow vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on an affected system.
