The vulnerability is due to insufficient input validation and file-level permissions. An attacker could exploit this vulnerability by uploading invalid files to an affected device, Cisco said.<\/li>\n<li>A <a href=\"https:\/\/tools.cisco.com\/security\/center\/content\/CiscoSecurityAdvisory\/cisco-sa-20190320-ipab\" rel=\"nofollow\">weakness<\/a> in the web-based management interface of SIP Software for Cisco&nbsp;IP Phone 8800 Series could allow an unauthenticated, remote attacker to bypass authorization, access critical services and cause a denial of service (DoS) condition. The vulnerability exists because the software fails to sanitize URLs before it handles requests. An attacker could exploit this vulnerability by submitting a crafted URL, Cisco said.<\/li>\n<li>An <a href=\"https:\/\/tools.cisco.com\/security\/center\/content\/CiscoSecurityAdvisory\/cisco-sa-20190320-ip-phone-csrf\" rel=\"nofollow\">exposure<\/a> in the web-based management interface of SIP Software for Cisco IP Phone 8800 Series could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack. The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading an authenticated user of the interface to follow a crafted link, Cisco said.<\/li>\n<\/ul>\n<p>Cisco said these vulnerabilities affect Cisco IP Phones running a SIP software release prior to 11.0 for Wireless IP Phone 8821-EX and release 12.5 SR1 for the IP Conference Phone 8832 and the rest of the IP Phone 8800 Series.<\/p>\n<p>The last vulnerability impacts <a href=\"https:\/\/tools.cisco.com\/security\/center\/content\/CiscoSecurityAdvisory\/cisco-sa-20190320-ip-phone-rce\" rel=\"nofollow\">both phones<\/a>. The problem is a weakness is in the web-based management interface of SIP software for Cisco&nbsp;IP Phone 7800 Series and Cisco&nbsp;IP Phone 8800 Series. A successful exploit could allow the attacker to trigger a reload of an affected device, resulting in a DoS condition or to execute arbitrary code with the privileges of the app user. Cisco wrote that the vulnerability exists because the software improperly validates user-supplied input during user authentication. An attacker could exploit this vulnerability by connecting to an affected device using HTTP and supplying malicious user credentials.<\/p>\n<p>Cisco said that the weakness involves version 10.3 SR5 for Unified IP Conference Phone 8831; 11.0 SR3 for Wireless IP Phone 8821 and 8821-EX; and 12.5 SR1 for the rest of the IP Phone 7800 and 8800 Series.<\/p>\n<aside class=\"nativo-promo nativo-promo-1 smartphone\" id><\/aside>\n<p>Cisco said it has released free patches for all the advisories and suggests going <a href=\"https:\/\/www.cisco.com\/c\/en\/us\/about\/legal\/cloud-and-software\/end_user_license_agreement.html\" rel=\"nofollow\">here<\/a> to see how to download them.&nbsp;<\/p>\n<aside id=\"fsb-2599\" class=\"fakesidebar fakesidebar-auto fakesidebar-sponsored\"><strong>[ <a href=\"https:\/\/pluralsight.pxf.io\/c\/321564\/424552\/7490?u=https%3A%2F%2Fwww.pluralsight.com%2Fpaths%2Fcertified-information-systems-security-professional-cisspr\" rel=\"nofollow\">Prepare to become a Certified Information Security Systems Professional with this comprehensive online course from PluralSight.
