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. A successful exploit could allow the attacker to gain unauthorized access to critical services and cause a DoS condition. This vulnerability affects Cisco IP Phone 8800 Series products running a SIP Software release prior to 11.0(5) for Wireless IP Phone 8821 and 8821-EX; and 12.5(1)SR1 for the IP Conference Phone 8832 and the rest of the IP Phone 8800 Series. Cisco IP Conference Phone 8831 is not affected.","severity":{"version":"3.0","score":7.5,"vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-08","score":0.01939,"percentile":0.80248,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-284"],"published":"2019-03-22T20:05:34Z","modified":"2026-06-17T02:29:15Z","products":[{"vendor":"cisco","product":"cisco ip conference phone 8832 and the rest of the ip phone 8800 series"},{"vendor":"cisco","product":"cisco wireless ip phone 8821 and 8821-ex"},{"vendor":"cisco","product":"ip_conference_phone_8832_firmware"},{"vendor":"cisco","product":"ip_phone_8800_firmware"},{"vendor":"cisco","product":"ip_phone_8821-ex_firmware"},{"vendor":"cisco","product":"ip_phone_8821_firmware"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190320-ipab","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2019-1763"},{"url":"https://github.com/advisories/GHSA-p8vp-w9wf-97hp"}],"sources":{"cve":[{"id":"CVE-2019-1763","title":"Cisco IP Phone 8800 Series Authorization Bypass Vulnerability","description":"A vulnerability in the web-based management interface of Session Initiation Protocol (SIP) Software for Cisco IP Phone 8800 Series could allow an unauthenticated, remote attacker to bypass authorization, access critical services, and cause a denial of service (DoS) condition.
