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-2024-13939 in the wild and no public exploit code.\n\nAffected product: FRACTAL String::Compare::ConstantTime. 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-2024-13939/ (Markdown: https://insights.sbomify.com/CVE-2024-13939/index.md)","id":"CVE-2024-13939","markdown":"https://insights.sbomify.com/CVE-2024-13939/index.md","name":"CVE-2024-13939","record":{"aliases":["DEBIAN-CVE-2024-13939","GHSA-x2v7-w9j6-rqmx","UBUNTU-CVE-2024-13939"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl string comparison library","requires_auth":"none","summary":"Attackers can determine the length of secret strings via timing attacks in the Perl String::Compare::ConstantTime library.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[{"product":"string\\","vendor":"fractal"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"},{"id":"CWE-208","name":"Observable Timing Discrepancy"}],"description":"String::Compare::ConstantTime for Perl through 0.321 is vulnerable to timing attacks that allow an attacker to guess the length of a secret string.\n\nAs stated in the documentation: \"If the lengths of the strings are different, because equals returns false right away the size of the secret string may be leaked (but not its contents).\"\n\nThis is similar to CVE-2020-36829","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":"Information disclosure in String::Compare::ConstantTime","id":"CVE-2024-13939","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Ninja Forms Webhooks \u003c= 3.0.7 - Authenticated (Admin+) Server-Side Request Forgery via Form Webhook","id":"CVE-2024-13940"},"packages":[],"prev":{"headline":"FoodBakery | Delivery Restaurant Directory WordPress Theme \u003c= 4.7 - Cross-Site Request Forgery in Multiple Functions","id":"CVE-2024-13933"},"products":["String::Compare::ConstantTime"],"published":"2025-03-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-28","vendors":["FRACTAL"]},"summary":"Attackers can determine the length of secret strings via timing attacks in the Perl String::Compare::ConstantTime library.","url":"https://insights.sbomify.com/CVE-2024-13939/"}
