Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2022-20781 in the wild and no public exploit code.\n\nAffected product: Cisco Asyncos. 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-2022-20781/ (Markdown: https://insights.sbomify.com/CVE-2022-20781/index.md)","id":"CVE-2022-20781","markdown":"https://insights.sbomify.com/CVE-2022-20781/index.md","name":"CVE-2022-20781","record":{"aliases":["GHSA-crgq-qmwc-cc89"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Web Security Appliance","requires_auth":"low_privilege","summary":"Authenticated attackers can inject malicious scripts into the Cisco WSA management interface, allowing arbitrary code execution in the victim's browser context.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"asyncos","vendor":"cisco"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface of an affected device. The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by inserting malicious data into a specific data field in an affected interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface.","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 Web Security Appliance Stored Cross-Site Scripting Vulnerability","id":"CVE-2022-20781","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:asyncos","products":["cisco:asyncos"],"type":"xss","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Identity Services Engine Sensitive Information Disclosure Vulnerability","id":"CVE-2022-20782"},"packages":[],"prev":{"headline":"Cisco Enterprise NFV Infrastructure Software Vulnerabilities","id":"CVE-2022-20780"},"products":["Cisco Web Security Appliance (WSA)"],"published":"2022-04-06","related":[{"cvss_score":10,"headline":"Cisco Multiple Products Improper Input Validation","id":"CVE-2025-20393","kev_date_added":"2025-12-17","published":"2025-12-17"},{"cvss_score":9.8,"headline":"Cisco Secure Email Gateway Relative Path Traversal","id":"CVE-2026-76519","kev_date_added":"2026-10-14","published":"2026-10-14"},{"cvss_score":9.8,"headline":"Cisco Secure Email Gateway SQL Injection","id":"CVE-2026-76461","kev_date_added":"2026-09-14","published":"2026-09-14"},{"cvss_score":8.8,"headline":"Command injection in Cisco Secure Web Appliance","id":"CVE-2024-20435","kev_date_added":null,"published":"2024-07-17"},{"cvss_score":8.8,"headline":"Cisco Web Security Appliance Unauthorized Device Reset Vulnerability","id":"CVE-2019-15956","kev_date_added":null,"published":"2019-11-26"},{"cvss_score":8.6,"headline":"Cisco Web Security Appliance Proxy Service Denial of Service Vulnerability","id":"CVE-2021-34698","kev_date_added":null,"published":"2021-10-06"},{"cvss_score":8.6,"headline":"Cisco Email Security Appliance Denial of Service Vulnerability","id":"CVE-2019-1947","kev_date_added":null,"published":"2020-09-23"}],"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":"2024-11-06","vendors":["Cisco"]},"summary":"Authenticated attackers can inject malicious scripts into the Cisco WSA management interface, allowing arbitrary code execution in the victim's browser context.","url":"https://insights.sbomify.com/CVE-2022-20781/"}
