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-2020-5230 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.opencastproject:base (Maven): affected all versions; fixed in 7.6\n- org.opencastproject:base (Maven): affected all versions; fixed in 7.6\n- org.opencastproject:base (Maven): affected from 8.0; fixed in 8.1\n- org.opencastproject:base (Maven): affected from 8.0; fixed in 8.1\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-2020-5230/ (Markdown: https://insights.sbomify.com/CVE-2020-5230/index.md)","id":"CVE-2020-5230","markdown":"https://insights.sbomify.com/CVE-2020-5230/index.md","name":"CVE-2020-5230","record":{"aliases":["GHSA-w29m-fjp4-qhmq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Opencast media platform","requires_auth":"low_privilege","summary":"Attackers can use unsafe identifiers to escape working directories and write files to arbitrary locations, potentially leading to code execution.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"opencast","vendor":"apereo"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"},{"id":"CWE-99","name":"Improper Control of Resource Identifiers"}],"description":"Opencast before 8.1 and 7.6 allows almost arbitrary identifiers for media packages and elements to be used. This can be problematic for operation and security since such identifiers are sometimes used for file system operations which may lead to an attacker being able to escape working directories and write files to other locations. In addition, Opencast's Id.toString(…) vs Id.compact(…) behavior, the latter trying to mitigate some of the file system problems, can cause errors due to identifier mismatch since an identifier may unintentionally change.
