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-2021-34787 in the wild and no public exploit code.\n\nAffected product: Cisco Adaptive Security Appliance. 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-2021-34787/ (Markdown: https://insights.sbomify.com/CVE-2021-34787/index.md)","id":"CVE-2021-34787","markdown":"https://insights.sbomify.com/CVE-2021-34787/index.md","name":"CVE-2021-34787","record":{"aliases":["GHSA-9jgg-4q8x-859v"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Cisco ASA/FTD firewall","requires_auth":"none","summary":"Remote attackers can bypass ACL rules and security protections on Cisco ASA/FTD devices configured with object group search.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"adaptive_security_appliance","vendor":"cisco"},{"product":"adaptive_security_appliance_software","vendor":"cisco"},{"product":"asa_5505_firmware","vendor":"cisco"},{"product":"asa_5512-x_firmware","vendor":"cisco"},{"product":"asa_5515-x_firmware","vendor":"cisco"},{"product":"asa_5525-x_firmware","vendor":"cisco"},{"product":"asa_5545-x_firmware","vendor":"cisco"},{"product":"asa_5555-x_firmware","vendor":"cisco"},{"product":"asa_5580_firmware","vendor":"cisco"},{"product":"asa_5585-x_firmware","vendor":"cisco"},{"product":"secure_firewall_threat_defense","vendor":"cisco"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-755","name":"Improper Handling of Exceptional Conditions"},{"id":"CWE-183","name":"Permissive List of Allowed Inputs"}],"description":"A vulnerability in the identity-based firewall (IDFW) rule processing feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass security protections.

An attacker could exploit this vulnerability by sending a specially crafted network request to an affected device. A successful exploit could allow the attacker to bypass access control list (ACL) rules on the device, bypass security protections, and send network traffic to unauthorized hosts.","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":"Security feature bypass in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2021-34787","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:adaptive_security_appliance","products":["cisco:adaptive_security_appliance","cisco:adaptive_security_appliance_software","cisco:secure_firewall_threat_defense"],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Race condition in Cisco AnyConnect Secure Mobility Client","id":"CVE-2021-34788"},"packages":[],"prev":{"headline":"Cisco BroadWorks CommPilot Application Software Vulnerabilities","id":"CVE-2021-34786"},"products":["Cisco Adaptive Security Appliance (ASA) Software"],"published":"2021-10-27","related":[{"cvss_score":8.6,"headline":"Denial of service in Cisco Adaptive Security Appliance Software","id":"CVE-2021-1573","kev_date_added":null,"published":"2022-01-11"},{"cvss_score":8.6,"headline":"Denial of service in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2021-34793","kev_date_added":null,"published":"2021-10-27"},{"cvss_score":8.6,"headline":"Denial of service in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2021-40117","kev_date_added":null,"published":"2021-10-27"},{"cvss_score":8.6,"headline":"Denial of service in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2021-40118","kev_date_added":null,"published":"2021-10-27"},{"cvss_score":8.6,"headline":"Denial of service in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2020-3304","kev_date_added":null,"published":"2020-10-21"},{"cvss_score":8.6,"headline":"File upload in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2020-3436","kev_date_added":null,"published":"2020-10-21"},{"cvss_score":8.6,"headline":"Denial of service in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2020-3528","kev_date_added":null,"published":"2020-10-21"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-07","vendors":["Cisco"]},"summary":"Remote attackers can bypass ACL rules and security protections on Cisco ASA/FTD devices configured with object group search.","url":"https://insights.sbomify.com/CVE-2021-34787/"}
