An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-8254 in the wild and no public exploit code.\n\nAffected product: Pulse Secure Desktop Client. 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-2020-8254/ (Markdown: https://insights.sbomify.com/CVE-2020-8254/index.md)","id":"CVE-2020-8254","markdown":"https://insights.sbomify.com/CVE-2020-8254/index.md","name":"CVE-2020-8254","record":{"aliases":["GHSA-p993-j26m-6v98"],"analysis":{"component_type":"desktop_application","fix_type":"configuration_change","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Pulse Secure Desktop Client","requires_auth":"none","summary":"Attackers can achieve remote code execution on Windows clients by tricking users into connecting to a malicious server, mitigated by disabling dynamic certificate trust.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"pulse_secure_desktop_client","vendor":"pulsesecure"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"},{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"A vulnerability in the Pulse Secure Desktop Client \u003c 9.1R9 has Remote Code Execution (RCE) if users can be convinced to connect to a malicious server.
