An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-1922 in the wild and no public exploit code.\n\nAffected product: Cisco IP Phone 8800 Series Software. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2019-1922/ (Markdown: https://insights.sbomify.com/CVE-2019-1922/index.md)","id":"CVE-2019-1922","markdown":"https://insights.sbomify.com/CVE-2019-1922/index.md","name":"CVE-2019-1922","record":{"aliases":["GHSA-996r-f8xw-6h6p"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco IP Phone","requires_auth":"none","summary":"Remote attackers can cause Cisco IP phones to reboot and fail registration by sending malformed SIP packets during the registration process.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ip_conference_phone_7832_firmware","vendor":"cisco"},{"product":"ip_conference_phone_8832_firmware","vendor":"cisco"},{"product":"ip_phone_7811_firmware","vendor":"cisco"},{"product":"ip_phone_7821_firmware","vendor":"cisco"},{"product":"ip_phone_7841_firmware","vendor":"cisco"},{"product":"ip_phone_7861_firmware","vendor":"cisco"},{"product":"ip_phone_8811_firmware","vendor":"cisco"},{"product":"ip_phone_8841_firmware","vendor":"cisco"},{"product":"ip_phone_8845_firmware","vendor":"cisco"},{"product":"ip_phone_8851_firmware","vendor":"cisco"},{"product":"ip_phone_8861_firmware","vendor":"cisco"},{"product":"ip_phone_8865_firmware","vendor":"cisco"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A vulnerability in Cisco SIP IP Phone Software for Cisco IP Phone 7800 Series and 8800 Series could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected phone. The vulnerability is due to insufficient validation of input Session Initiation Protocol (SIP) packets. An attacker could exploit this vulnerability by altering the SIP replies that are sent to the affected phone during the registration process. A successful exploit could allow the attacker to cause the phone to reboot and not complete the registration process.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cisco IP Phone 7800 and 8800 Series Session Initiation Protocol Denial of Service Vulnerability","id":"CVE-2019-1922","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Small Business SPA500 Series IP Phones Local Command Execution Vulnerability","id":"CVE-2019-1923"},"packages":[],"prev":{"headline":"Cisco Email Security Appliance Content Filter Bypass Vulnerability","id":"CVE-2019-1921"},"products":["Cisco IP Phone 8800 Series Software"],"published":"2019-07-06","related":[{"cvss_score":8.8,"headline":"Cisco IP Phone Remote Code Execution and Denial of Service Vulnerability","id":"CVE-2020-3111","kev_date_added":null,"published":"2020-02-05"},{"cvss_score":7.5,"headline":"Cisco IP Phone 7800 Series and 8800 Series Session Initiation Protocol XML Denial of Service Vulnerability","id":"CVE-2019-1635","kev_date_added":null,"published":"2019-05-03"},{"cvss_score":6.5,"headline":"Memory corruption in Cisco IP Phones with Multiplatform Firmware","id":"CVE-2021-1379","kev_date_added":null,"published":"2024-11-18"},{"cvss_score":6.5,"headline":"Denial of service in Cisco IP Phone 8800 Series Software","id":"CVE-2019-1684","kev_date_added":null,"published":"2019-02-21"},{"cvss_score":5.5,"headline":"Cisco IP Phone Software Arbitrary File Read Vulnerability","id":"CVE-2021-34711","kev_date_added":null,"published":"2021-10-06"},{"cvss_score":4.6,"headline":"Cisco IP Phones Information Disclosure Vulnerability","id":"CVE-2022-20660","kev_date_added":null,"published":"2022-01-14"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-21","vendors":["Cisco"]},"summary":"Remote attackers can cause Cisco IP phones to reboot and fail registration by sending malformed SIP packets during the registration process.","url":"https://insights.sbomify.com/CVE-2019-1922/"}
