An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-27977 in the wild and no public exploit code.\n\nAffected product: Schneider Electric Custom Reports (RMS16.dll). 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-2023-27977/ (Markdown: https://insights.sbomify.com/CVE-2023-27977/index.md)","id":"CVE-2023-27977","markdown":"https://insights.sbomify.com/CVE-2023-27977/index.md","name":"CVE-2023-27977","record":{"aliases":["GHSA-8c9m-95jr-9f2r"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"IGSS Data Server","requires_auth":"none","summary":"An attacker can delete files in the IGSS project report directory by sending crafted messages to the Data Server TCP port, causing data loss.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"custom_reports","vendor":"schneider-electric"},{"product":"igss_dashboard","vendor":"schneider-electric"},{"product":"igss_data_server","vendor":"schneider-electric"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"A CWE-345: Insufficient Verification of Data Authenticity vulnerability exists in the Data Server that could cause access to delete files in the IGSS project report directory, this could lead to loss of data when an attacker sends specific crafted messages to the Data Server TCP port.
