An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-15396 in the wild and no public exploit code.\n\nAffected product: Cisco Unity Connection. 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-2018-15396/ (Markdown: https://insights.sbomify.com/CVE-2018-15396/index.md)","id":"CVE-2018-15396","markdown":"https://insights.sbomify.com/CVE-2018-15396/index.md","name":"CVE-2018-15396","record":{"aliases":["GHSA-fvmw-88r5-vrp4"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Unity Connection","requires_auth":"high_privilege","summary":"An authenticated administrator can cause a denial of service by uploading large files that exhaust disk space in Cisco Unity Connection.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"unity_connection","vendor":"cisco"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"},{"id":"CWE-399","name":null}],"description":"A vulnerability in the Bulk Administration Tool (BAT) for Cisco Unity Connection could allow an authenticated, remote attacker to cause high disk utilization, resulting in a denial of service (DoS) condition. The vulnerability exists because the affected software does not restrict the maximum size of certain files that can be written to disk. An attacker who has valid administrator credentials for an affected system could exploit this vulnerability by sending a crafted, remote connection request to an affected system. A successful exploit could allow the attacker to write a file that consumes most of the available disk space on the system, causing application functions to operate abnormally and leading to a DoS condition.","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 Unity Connection File Upload Denial of Service Vulnerability","id":"CVE-2018-15396","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:unity_connection","products":["cisco:unity_connection"],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Cisco Adaptive Security Appliance IPsec VPN Denial of Service Vulnerability","id":"CVE-2018-15397"},"packages":[],"prev":{"headline":"Cisco Wireless LAN Controller Software Privilege Escalation Vulnerability","id":"CVE-2018-15395"},"products":["Cisco Unity Connection"],"published":"2018-10-05","related":[{"cvss_score":9,"headline":"Privilege escalation in n/a","id":"CVE-2014-3333","kev_date_added":null,"published":"2014-08-11"},{"cvss_score":9,"headline":"Privilege escalation in n/a","id":"CVE-2012-0366","kev_date_added":null,"published":"2012-03-01"},{"cvss_score":8.8,"headline":"Cisco Unity Connection Remote Code Execution Vulnerability","id":"CVE-2026-20034","kev_date_added":null,"published":"2026-05-06"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2012-3060","kev_date_added":null,"published":"2012-09-16"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2012-0367","kev_date_added":null,"published":"2012-03-01"},{"cvss_score":7.3,"headline":"File upload in Cisco Unity Connection","id":"CVE-2024-20272","kev_date_added":null,"published":"2024-01-17"},{"cvss_score":7.2,"headline":"Cisco Unity Connection Server-Side Request Forgery Vulnerability","id":"CVE-2026-20035","kev_date_added":null,"published":"2026-05-06"}],"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":"2024-11-26","vendors":["Cisco"]},"summary":"An authenticated administrator can cause a denial of service by uploading large files that exhaust disk space in Cisco Unity Connection.","url":"https://insights.sbomify.com/CVE-2018-15396/"}
