An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3310 in the wild and no public exploit code.\n\nAffected product: Cisco Firepower Threat Defense 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-2020-3310/ (Markdown: https://insights.sbomify.com/CVE-2020-3310/index.md)","id":"CVE-2020-3310","markdown":"https://insights.sbomify.com/CVE-2020-3310/index.md","name":"CVE-2020-3310","record":{"aliases":["GHSA-mwm2-vw9r-qw3f"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Firepower Device Manager","requires_auth":"high_privilege","summary":"Authenticated attackers can cause system instability or reload by uploading or sending malicious XML files to Cisco Firepower Device Manager.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"firepower_device_manager_on-box","vendor":"cisco"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:L","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability in the XML parser code of Cisco Firepower Device Manager On-Box software could allow an authenticated, remote attacker to cause an affected system to become unstable or reload. The vulnerability is due to insufficient hardening of the XML parser configuration. An attacker could exploit this vulnerability in multiple ways using a malicious file: An attacker with administrative privileges could upload a malicious XML file on the system and cause the XML code to parse the malicious file. An attacker with Clientless Secure Sockets Layer (SSL) VPN access could exploit this vulnerability by sending a crafted XML file. A successful exploit would allow the attacker to crash the XML parser process, which could cause system instability, memory exhaustion, and in some cases lead to a reload of the affected system.","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 Device Manager On-Box Software XML Parsing Vulnerability","id":"CVE-2020-3310","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Firepower Management Center Open Redirect Vulnerability","id":"CVE-2020-3311"},"packages":[],"prev":{"headline":"Cisco Firepower Device Manager On-Box Software Arbitrary File Overwrite Vulnerability","id":"CVE-2020-3309"},"products":["Cisco Firepower Threat Defense Software"],"published":"2020-05-06","related":[{"cvss_score":6.5,"headline":"Cisco Firepower Device Manager On-Box Software Arbitrary File Overwrite Vulnerability","id":"CVE-2020-3309","kev_date_added":null,"published":"2020-05-06"},{"cvss_score":6.3,"headline":"Cisco Firepower Device Manager On-Box Software Remote Code Execution Vulnerability","id":"CVE-2021-1518","kev_date_added":null,"published":"2021-07-22"}],"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":"2024-11-15","vendors":["Cisco"]},"summary":"Authenticated attackers can cause system instability or reload by uploading or sending malicious XML files to Cisco Firepower Device Manager.","url":"https://insights.sbomify.com/CVE-2020-3310/"}
