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-2021-27768 in the wild and no public exploit code.\n\nAffected product: HCL Software Verse for Android. 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-2021-27768/ (Markdown: https://insights.sbomify.com/CVE-2021-27768/index.md)","id":"CVE-2021-27768","markdown":"https://insights.sbomify.com/CVE-2021-27768/index.md","name":"CVE-2021-27768","record":{"aliases":["GHSA-v5hf-q535-5h32"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"HCL Verse Android app","requires_auth":"low_privilege","summary":"Attackers can intercept sensitive account information via Man-in-the-Middle attacks due to missing SSL hostname verification in the HCL Verse Android application.","user_interaction":"required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HCL","cpe":[{"product":"verse","vendor":"hcltech"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"},{"id":"CWE-300","name":"Channel Accessible by Non-Endpoint"}],"description":"Using the ability to perform a Man-in-the-Middle (MITM) attack, which indicates a lack of hostname verification, sensitive account information was able to be intercepted.
