It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-31155 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pleaser (crates.io): affected all versions; fixed in 0.4.0\n- pleaser (crates.io): affected all versions; fixed in 0.4.0\n- pleaser (crates.io): affected from 0.0.0-0; fixed in 0.4.0\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-2021-31155/ (Markdown: https://insights.sbomify.com/CVE-2021-31155/index.md)","id":"CVE-2021-31155","markdown":"https://insights.sbomify.com/CVE-2021-31155/index.md","name":"CVE-2021-31155","record":{"aliases":["DEBIAN-CVE-2021-31155","GHSA-vc5p-j8vw-mc6x","RUSTSEC-2021-0101"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Rust privilege tool","requires_auth":"low_privilege","summary":"A local attacker can gain full root privileges by exploiting improper umask handling in the please tool.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"umask","vendor":"umask_project"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"Failure to normalize the umask in please before 0.4 allows a local attacker to gain full root privileges if they are allowed to execute at least one command.","ecosystems":["crates.io"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Permissions bypass in pleaser","id":"CVE-2021-31155","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":3,"n_references":2,"next":{"headline":"Path traversal in n/a","id":"CVE-2021-31156"},"packages":[{"ecosystem":"crates.io","fixed":["0.4.0"],"introduced":["0"],"last_affected":[],"package":"pleaser","purl":null,"source":"GHSA-vc5p-j8vw-mc6x"},{"ecosystem":"crates.io","fixed":["0.4.0"],"introduced":["0"],"last_affected":[],"package":"pleaser","purl":"pkg:cargo/pleaser","source":"GHSA-vc5p-j8vw-mc6x"},{"ecosystem":"crates.io","fixed":["0.4.0"],"introduced":["0.0.0-0"],"last_affected":[],"package":"pleaser","purl":"pkg:cargo/pleaser","source":"RUSTSEC-2021-0101"}],"prev":{"headline":"Permissions bypass in pleaser","id":"CVE-2021-31154"},"products":["n/a"],"published":"2021-05-27","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"A local attacker can gain full root privileges by exploiting improper umask handling in the please tool.","url":"https://insights.sbomify.com/CVE-2021-31155/"}
