Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-26031 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.hadoop:hadoop-yarn-project (Maven): affected from 3.3.1; fixed in 3.3.5\n- org.apache.hadoop:hadoop-yarn-project (Maven): affected from 3.3.1; fixed in 3.3.5\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-2023-26031/ (Markdown: https://insights.sbomify.com/CVE-2023-26031/index.md)","id":"CVE-2023-26031","markdown":"https://insights.sbomify.com/CVE-2023-26031/index.md","name":"CVE-2023-26031","record":{"aliases":["GHSA-94jh-j374-9r3j"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Hadoop YARN","requires_auth":"low_privilege","summary":"Local attackers can gain root privileges via malicious library injection in the container-executor binary, potentially affecting remote users if YARN secure containers are enabled.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"hadoop","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-426","name":"Untrusted Search Path"}],"description":"Relative library resolution in linux container-executor binary in Apache Hadoop 3.3.1-3.3.4 on Linux allows local user to gain root privileges. If the YARN cluster is accepting work from remote (authenticated) users, this MAY permit remote users to gain root privileges.\n\nHadoop 3.3.0 updated the \" YARN Secure Containers https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/SecureContainer.html \" to add a feature for executing user-submitted applications in isolated linux containers.\n\nThe native binary HADOOP_HOME/bin/container-executor is used to launch these containers; it must be owned by root and have the suid bit set in order for the YARN processes to run the containers as the specific users submitting the jobs.\n\nThe patch \" YARN-10495 https://issues.apache.org/jira/browse/YARN-10495 . make the rpath of container-executor configurable\" modified the library loading path for loading .so files from \"$ORIGIN/\" to \"\"$ORIGIN/:../lib/native/\". This is the a path through which libcrypto.so is located. Thus it is is possible for a user with reduced privileges to install a malicious libcrypto library into a path to which they have write access, invoke the container-executor command, and have their modified library executed as root.\nIf the YARN cluster is accepting work from remote (authenticated) users, and these users' submitted job are executed in the physical host, rather than a container, then the CVE permits remote users to gain root privileges.\n\nThe fix for the vulnerability is to revert the change, which is done in  YARN-11441 https://issues.apache.org/jira/browse/YARN-11441 , \"Revert YARN-10495\". This patch is in hadoop-3.3.5.\n\nTo determine whether a version of container-executor is vulnerable, use the readelf command.
