An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-2516 exists.\n\nAffected product: Kingsoft WPS Office. 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-2025-2516/ (Markdown: https://insights.sbomify.com/CVE-2025-2516/index.md)","id":"CVE-2025-2516","markdown":"https://insights.sbomify.com/CVE-2025-2516/index.md","name":"CVE-2025-2516","record":{"aliases":["GHSA-cvv7-5999-m892"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WPS Office","requires_auth":"none","summary":"Weak cryptographic keys in WPS Office allow attackers to sign malicious components and hijack updates via man-in-the-middle attacks.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ESET","cpe":[],"cvss":{"score":9.5,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-326","name":"Inadequate Encryption Strength"}],"description":"The use of a weak cryptographic key pair in the signature verification process in WPS Office (Kingsoft) on Windows allows an attacker who successfully recovered the private key to sign components.\n\nAs older versions of WPS Office did not validate the update server's certificate, an Adversary-In-The-Middle attack was possible allowing updates to be hijacked.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Use of a weak cryptographic key in the signature verification process in WPS Office","id":"CVE-2025-2516","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Reference to Expired Domain Vulnerability in OpenText™ ArcSight Enterprise Security Manager","id":"CVE-2025-2517"},"packages":[],"prev":{"headline":"Bluechi: privilege escalation in bluechi via unrestricted cross-node systemd dependencies","id":"CVE-2025-2515"},"products":["WPS Office"],"published":"2025-03-27","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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-03-27","vendors":["Kingsoft"]},"summary":"Weak cryptographic keys in WPS Office allow attackers to sign malicious components and hijack updates via man-in-the-middle attacks.","url":"https://insights.sbomify.com/CVE-2025-2516/"}
