An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-15390 in the wild and no public exploit code.\n\nAffected product: Cisco Secure Firewall Threat Defense. 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-2018-15390/ (Markdown: https://insights.sbomify.com/CVE-2018-15390/index.md)","id":"CVE-2018-15390","markdown":"https://insights.sbomify.com/CVE-2018-15390/index.md","name":"CVE-2018-15390","record":{"aliases":["GHSA-2wx9-x824-p464"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Cisco FTD Software","requires_auth":"none","summary":"Remote attackers can cause a denial of service on Cisco Firepower Threat Defense devices by triggering a memory-related panic in the FTP inspection engine.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"secure_firewall_threat_defense","vendor":"cisco"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-667","name":"Improper Locking"},{"id":"CWE-399","name":null}],"description":"A vulnerability in the FTP inspection engine of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability exists because the affected software fails to release spinlocks when a device is running low on system memory, if the software is configured to apply FTP inspection and an access control rule to transit traffic, and the access control rule is associated with an FTP file policy. An attacker could exploit this vulnerability by sending a high rate of transit traffic through an affected device to cause a low-memory condition on the device. A successful exploit could allow the attacker to cause a software panic on the affected device, which could cause the device to reload and result in a temporary 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 Firepower Threat Defense Software FTP Inspection Denial of Service Vulnerability","id":"CVE-2018-15390","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:secure_firewall_threat_defense","products":["cisco:secure_firewall_threat_defense"],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Cisco Remote PHY IPv4 Fragment Denial of Service Vulnerability","id":"CVE-2018-15391"},"packages":[],"prev":{"headline":"Cisco Prime Collaboration Provisioning Intermittent Hard-Coded Password Vulnerability","id":"CVE-2018-15389"},"products":["Cisco Firepower Threat Defense Software"],"published":"2018-10-05","related":[{"cvss_score":9.3,"headline":"Hardcoded credentials in Cisco Firepower Threat Defense Software","id":"CVE-2024-20412","kev_date_added":null,"published":"2024-10-23"},{"cvss_score":8.6,"headline":"Memory corruption in Cisco Firepower Threat Defense Software","id":"CVE-2024-20330","kev_date_added":null,"published":"2024-10-23"},{"cvss_score":8.6,"headline":"Cisco Firepower Threat Defense Software for Firepower 2100 Series TLS Denial of Service Vulnerability","id":"CVE-2024-20339","kev_date_added":null,"published":"2024-10-23"},{"cvss_score":8.6,"headline":"Cisco Firepower Threat Defense Software Snort Firewall Denial of Service Vulnerability","id":"CVE-2024-20351","kev_date_added":null,"published":"2024-10-23"},{"cvss_score":8.6,"headline":"Denial of service in Cisco Firepower Threat Defense Software","id":"CVE-2023-20083","kev_date_added":null,"published":"2023-11-01"},{"cvss_score":8.6,"headline":"Denial of service in Cisco Firepower Threat Defense Software","id":"CVE-2023-20244","kev_date_added":null,"published":"2023-11-01"},{"cvss_score":8.6,"headline":"Memory corruption in Cisco Firepower Threat Defense Software","id":"CVE-2022-20946","kev_date_added":null,"published":"2022-11-10"}],"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":"Remote attackers can cause a denial of service on Cisco Firepower Threat Defense devices by triggering a memory-related panic in the FTP inspection engine.","url":"https://insights.sbomify.com/CVE-2018-15390/"}
