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-2025-11233 in the wild and no public exploit code.\n\nAffected product: Rust Project std. 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-2025-11233/ (Markdown: https://insights.sbomify.com/CVE-2025-11233/index.md)","id":"CVE-2025-11233","markdown":"https://insights.sbomify.com/CVE-2025-11233/index.md","name":"CVE-2025-11233","record":{"aliases":["DEBIAN-CVE-2025-11233","UBUNTU-CVE-2025-11233"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Rust standard library","requires_auth":"none","summary":"Rust standard library on Cygwin ignored backslashes, enabling path traversal in applications compiled for this specific target.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"rust","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L/AU:Y/RE:L/U:Green","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Starting from Rust 1.87.0 and before Rust 1.89.0, the tier 3 Cygwin target (`x86_64-pc-cygwin`) didn't correctly handle path separators, causing the standard library's Path API to ignore path components separated by backslashes. Due to this, programs compiled for Cygwin that validate paths could misbehave, potentially allowing path traversal attacks or malicious filesystem operations.\n\nRust 1.89.0 fixes the issue by handling both Win32 and Unix style paths in the standard library for the Cygwin target.\n\nWhile we assess the severity of this vulnerability as \"medium\", please note that the tier 3 Cygwin compilation target is only available when building it from source: no pre-built binaries are distributed by the Rust project, and it cannot be installed through Rustup. Unless you manually compiled the `x86_64-pc-cygwin` target you are not affected by this vulnerability. Users of the tier 1 MinGW target (`x86_64-pc-windows-gnu`) are also explicitly not affected.","ecosystems":[],"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":"Rust standard library didn't detect all path separators on Cygwin","id":"CVE-2025-11233","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Qemu-kvm: vnc websocket handshake use-after-free","id":"CVE-2025-11234"},"packages":[],"prev":{"headline":"Invalid characters cause assert","id":"CVE-2025-11232"},"products":["std"],"published":"2025-10-01","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-01","vendors":["Rust Project"]},"summary":"Rust standard library on Cygwin ignored backslashes, enabling path traversal in applications compiled for this specific target.","url":"https://insights.sbomify.com/CVE-2025-11233/"}
