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-2021-23052 in the wild and no public exploit code.\n\nAffected product: F5 Big-Ip Access Policy Manager. 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-2021-23052/ (Markdown: https://insights.sbomify.com/CVE-2021-23052/index.md)","id":"CVE-2021-23052","markdown":"https://insights.sbomify.com/CVE-2021-23052/index.md","name":"CVE-2021-23052","record":{"aliases":["GHSA-pjwq-vqfj-r3hh"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"BIG-IP APM","requires_auth":"none","summary":"An unauthenticated attacker can create an open redirect URI on BIG-IP APM virtual servers, potentially bypassing security controls.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[{"product":"big-ip_access_policy_manager","vendor":"f5"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"On version 14.1.x before 14.1.4.4 and all versions of 13.1.x, an open redirect vulnerability exists on virtual servers enabled with a BIG-IP APM access policy.
