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-2020-7520 in the wild and no public exploit code.\n\nAffected product: Schneider Electric Software Update (SESU) V2.4.0 and prior.. 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-2020-7520/ (Markdown: https://insights.sbomify.com/CVE-2020-7520/index.md)","id":"CVE-2020-7520","markdown":"https://insights.sbomify.com/CVE-2020-7520/index.md","name":"CVE-2020-7520","record":{"aliases":["GHSA-392j-2p2c-c7m3"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Schneider Electric Software Update","requires_auth":"none","summary":"An attacker with privileged access can modify registry keys to redirect update traffic, enabling a man-in-the-middle attack that leads to malicious code execution.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"software_update_utility","vendor":"schneider-electric"}],"cvss":{"score":4.7,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/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":"A CWE-601: URL Redirection to Untrusted Site ('Open Redirect') vulnerability exists in Schneider Electric Software Update (SESU), V2.4.0 and prior, which could cause execution of malicious code on the victim's machine.
